Error of quartz watches. FAQ on choosing a watch

Instructions

V10K High-Tech Diamant produced by the Swiss company Rado is the most durable watch in the world according to the Guinness Book of Records. The body contains diamond chips, providing a hardness of 10,000 on the Vickers scale. The laconic black bracelet is made of silicone. The design is minimalist: the stylish square dial displays the time and date, and the control buttons are located behind.

The most popular budget watches for extreme sports enthusiasts are the Japanese Casio G-Shock. The company regularly posts videos of crash tests that models of this line undergo. The case is designed for maximum shock absorption and water resistance. The clock mechanism is securely mounted to withstand any test. The functionality of the sports chronometer includes a timer, stopwatch, calendar, world and local time, as well as backlight.

The Swiss Military Watch 20"000 FEET looks stylish and respectable. Military watches are considered the most reliable because they undergo the most stringent tests. This model has been subjected to water pressure equivalent to 6 km of immersion and a blast wave. Rare watches can withstand a hit from a rifle, but Swiss Military Watch 20"000 FEET is equipped with a unique shock absorption system. The case and bracelet are made of titanium; a replaceable silicone bracelet is provided for diving.

The Chronograph Sport Tantalum Automatic sports watch from Montblanc is resistant to aggressive environments. They were tested with acids and alkalis, heated to 240°, and immersed in water, but the sealed tantalum case passed all tests. The representative design includes functionality typical for this class: time and date indicators, as well as a chronograph.

Swiss watches Certina DS are relatively inexpensive compared to luxury models, but are not inferior in technical characteristics. The case is made of stainless steel, and the dial is reliably protected by a sapphire crystal that can withstand water pressure at a depth of 200 m. The rubber bracelet is ideal for diving. The analog dial will be appreciated by fans of classic design.

The Royal Oak GMT Tourbillon Concept is best characterized by its unrivaled design: an open tourbillon in a carbon case and a double dial are typical of a high-end watch. This model is waterproof to a depth of 100 m, equipped with a chronograph and a power reserve indicator.

The Harry Winston Project Z5 jewelry watch emphasizes belonging to the cream of society. The reliable open tourbillon movement is covered with sapphire crystal and built into a zirconium case. A rubber bracelet allows you to go diving without parting with your favorite accessory. The double dial allows you to find out the exact time in all time zones.

Most luxury luxury watches are equipped with quartz movements. The only exception is the Suunto Ambit2 Sapphire. This digital watch has received the prestigious Red Dot Design Award. They have built-in not only standard functions for measuring time, but also a compass, thermometer, barometer, GPS sensor and heart rate meter. Of course, the watch is water-resistant and suitable for diving.

  • The most reliable watch in the world

Atomic clocks are the most accurate in the world, they have incredibly small errors that can reach up to a second in billions of years. The second place is occupied by quartz watches, which will lag or hurry by fifteen seconds in a month. Mechanical ones need to be started from time to time, so they are only in third place.

The most accurate atomic clocks

Atomic clocks are so accurate that their error is within a fraction of a second in billions of years—an error comparable to measuring the diameter of the Earth to the nearest atom. Of course, ordinary people do not need such watches in everyday life; scientists use them to conduct scientific experiments that require extreme precision. They make it possible to test the passage of time in different places on the planet or conduct experiments to confirm the general theory of relativity and other physical theories.

One American company plans to release a series of quantum watches for everyday use.

Some titanium or stainless steel watches are not coated with anything at all. On gold plated hours pay attention to the quality and thickness of the gilding layer. Never buy a watch with nickel plating - it is harmful to human health and can cause allergies.

Also, always pay attention to the quality of the watch bracelet - it should not wear out or lose its appearance over time, which means it should be metal. The bracelet should fit comfortably on your hand, and it should be securely attached to the watch case.

Some watches are made with protection from shock and moisture - such parameters increase their price, but at the same time increase the life of your watch.

If previously a watch was a necessity, now a mobile phone can handle its functions quite well. However, despite this, the watch still remains a sign of solidity and efficiency. If you decide to choose a wristwatch for yourself, but don’t know where to start, then the instructions below are for you.

Instructions

Decide on the watch mechanism you need. There are three types of watches: mechanical, quartz and electronic.
Mechanical watches operate on a tightly wound spring. The spring slowly unwinds and sets the pendulum in motion, which in turn makes the clock mechanism work. When this spring unwinds to the end, the watch stops and needs to be wound up again, that is, the spring must be tightened. The error of such watches ranges from 40 to -20 seconds per day, and to eliminate this, some watches are equipped with automatic winding.
Quartz watches are powered by a conventional or solar battery, and the pendulum in them is replaced by a quartz crystal. Quartz watches have an error of 20 to -20 seconds per month and do not need to be wound.

Electronic watches are also quartz watches, but with a digital display. If such a watch is in a hurry or behind, you can simply manually set the desired time.

Decide on the case of your future watch, because the durability, appearance and, importantly, the price of the product depend on this material.
The cheapest watches are made of aluminum and are very short-lived.

Plastic watches may also not be of the best quality, but you can also find very good and expensive ones, such as Casio watches.
Nickel-plated watches may cause allergies if worn constantly.

Choose a watch with a non-coated coating, as this coating can wear off and scratch over time, and then the watch will not look its best.

When choosing, pay attention to the dial and protective glass. The dial can have a very different appearance and can be painted in different colors. The hands can be phosphorized so that the time can be seen in the dark. Remember that the dial is the face of your watch.

Be responsible when choosing the material for your protective glass. The most durable material is artificial sapphire, the most popular is crystal, but plastic is the cheapest, but very short-lived, it is easy to scratch and becomes cloudy over time.

A wristwatch is not just a sign of a sense of style. For many, this is a necessary accessory that they cannot do without in everyday life. There are many brands of famous watch manufacturers. However, those watches whose homeland is Switzerland are rightfully considered to be of the highest quality.



The phrase “Swiss watches” sounds like a common noun: it means prestige, status, dignity, and, of course, reliable quality. Everyone dreams of owning such a watch, but not everyone can afford such luxury. And no time can change the popularity of watches from Switzerland. So what is the secret of such unprecedented excitement?

In Switzerland, there is a law that regulates the right of factories to label their watches as “Swiss made”. Only those products are awarded such a title, half of the parts of which are produced in this country. The movement and watch must also be assembled here and subject to quality certification in Switzerland. This is a requirement. If at least one of them is not met, then the watch will not be considered Swiss, but will become just a copy of its famous brothers.

Approximately one hundred Swiss companies can put the Swiss made mark on their products. Only after passing a thorough production and quality control check can a manufacturer receive the honor of imprinting the coveted phrase on its products. There is also a special bureau in Switzerland that monitors the quality of watches produced in this country.



A wristwatch is no longer an essential item, but an image accessory, the final chord of a stylish image for a business person, a metropolitan dandy or an athlete. Of course, a banker or official will not skimp on such a status item and will give preference to luxury and premium brands. But if you choose a watch for a teenager, there is no need for elite brands; inexpensive, high-quality watches are enough.

Mechanical or electronic watches?

The design of mechanical watches has been known for many years and has remained virtually unchanged. Such a device requires daily winding and wearing for at least 8 hours a day. Although they are very durable, repairing accidental breakdowns is time-consuming and expensive. This accessory is damaged by dust and humidity, and its accuracy fails. Despite such restrictions, the most expensive and high-status watches are hand-made mechanical ones.

Quartz watches look similar to mechanical watches, but they are actually powered by a battery. This design improvement increases the accuracy of operation and eliminates the need to rewind the device. Among quartz watches there are both budget models and stylish accessories for the middle class.

Finally, the most modern watches are electronic. Their display is backlit, and additional functions can be built in (alarm clock, stopwatch, tachometer, calendar, date and day of week indicators). Such a device is not affected by weather and atmospheric pressure, and the mechanism is housed in a waterproof case. Among the electronic watches there are examples with both a classic dial and a digital time display.

Materials for a good watch

When choosing a watch, it is important to consider the material from which the case and bracelet are made. Some metals, such as aluminum, nickel and their alloys, can cause allergies and skin irritation. In addition, aluminum is soft, impractical, and when oxidized, it leaves marks on the hand. If you are looking for a metal watch, take a look at surgical steel watches. The titanium case is considered the most prestigious.

Some manufacturers spray-coat the body, so you need to pay attention to its quality and the technology used to apply it. Don't go after cheap glamor: the gilding, both real and fake, will peel off in a couple of weeks. On the other hand, the PVD or IPG mark on the body will indicate that the coating will last as long as possible.

The strap material on good watches is genuine leather. Pay attention to how elastic, durable and pleasant the strap is to the touch, and whether there are any external defects. As for the protective glass, cheaper models are finished with plastic, while more expensive ones are finished with crystal or sapphire.

Choosing a manufacturer

Experience shows that when looking for inexpensive watches, you should not count on fakes from luxury brands: firstly, a fake looks funny and discredits your image, and secondly, it is not of high quality. But it’s worth taking a closer look at reliable quartz watches made in Japan and Switzerland: Casio, Citizen, Orient. These watches are equipped with automatic winding, they are waterproof, have a classic style and high quality.

  • Men's magazine MenPassion, article about choosing watches

Regardless of the price or country of origin of a watch, we expect one thing from them: accurate readings. Otherwise, why are they needed?!

First things first...

Important! The accuracy of any watch is affected by a number of factors.

  1. For mechanical watches:
  • The position of the clock in space,
  • Condition of the mechanism and parts,
  • Mainspring tension level.
  • For quartz:
    • Oscillator frequency (the higher the oscillation frequency, the more accurate the clock),
    • Aging of a quartz crystal.

Regardless of whether the watch is mechanical or quartz, it should be protected from the influence of temperature.

Remember, excessive sunbathing is contraindicated for hours, and it is better not to take it on a trip to the North Pole.

The influence of all these factors can lead to a running error mechanical watches -20/+40 seconds per day, quartz watches - +/-20 seconds per month.

And that's completely normal!

So, we demand maximum precision from watches. What are they, the most accurate watches?

The most accurate clock in the world is atomic, Quantum Logic Clock. They were recently created in the USA. True, they “escape” for a whole second in... 3.7 billion years

Everything would be fine, but this clock takes up the whole room!


Progress does not stand still, and, taking as a basis the principle of operation of the Quantum Logic Clock, Bathys Hawaii presented the first prototype of an ultra-precise wristwatch, Cesium 133. The stated error is no more than a second in 1000 years.


Not as accurate readings, but still as close as possible, are given by chronometers. Error of mechanical chronometers - -4/+6 seconds per day , quartz - +/-5 seconds per year . These watches have passed a number of tests and are certified by C.O.S.C.

Naturally, not all watches have this high rank. For example, some models from the Epos collection have passed all tests and proudly bear the status of “chronometer”.

Another prestigious complication that increases the accuracy of mechanical watches is the tourbillon. Watches with a tourbillon are quite expensive, but you don’t have to worry about accuracy - the maximum error is ±1/2 second per day .

Some watches are expensive, others cannot be worn on your hand due to their bulky size... What should you do if you want to find an accurate watch at an affordable price?

Agree, in ordinary life, knowing the time correct to the millisecond is not so important. Moreover, manufacturers already strive for maximum accuracy.

For example, watches with a radio control module Citizen Promaster Sky or Casio G-Shock in the Radio Controlled collection, having the possibility of radio synchronization, do not give any error at all, because They regularly check the time using a radio signal transmitted from atomic clocks. But this signal is not caught all over the world. So read the instructions carefully before purchasing to know the coverage areas.

In pursuit of absolute precision, another Japanese company, Seiko, competes with the developments of Casio and Citizen. The Astron GPS Solar watch can automatically connect to satellites, receiving data from any of Earth's 39 time zones and adjusting the time to the precision of atomic clocks.


If we talk about watches without the above technical capabilities, then Citizen announces its quartz Chronomaster watch with an annual error of ±5 seconds , as the most accurate in the world. Error +/-10 seconds per year they promise Bulova watches from the men's and women's Precisionist collections (English precision - “precision”).

If the clock begins to “chronically” rush or lag behind (mechanical for -20/+40 seconds per day, quartz for +/-20 seconds per month), this does not always mean a breakdown. The accuracy of the watch can be adjusted in a workshop.

But a more significant deviation from the indicated readings is an indicator of a malfunction and such watches need to be repaired, not adjusted.

Information and useful tips when choosing a watch
This topic DOES NOT CONSIDER CHEAP CHINESE CRAFTS and especially fakes. We kindly ask you not to write about them here.

Watches perform many functions: from a banal indication of time to a fashion accessory. Before you start making your choice, you need to know some technical and practical features of a wristwatch.

When approaching the issue of buying a watch, you need to clearly understand where you will most often wear it: to a business meeting, to a fitness club or to a noisy party. Watches, just like clothes and jewelry, are subject to the principle of matching the events where you plan to spend time.

It is not recommended to leave the watch near speakers or other sources of magnetic fields. Most watches do not have anti-magnetic protection, and when parts of the watch mechanism are magnetized, they may begin to lag or, conversely, move faster (for mechanics). And, of course, you shouldn’t repair expensive Swiss watches in the first workshop you come across - there are official service centers for this.

The main criteria in addition to the above are:

1. Type of mechanism.

All watches can be classified into only two groups: quartz and mechanical.

A quartz clock is a combination of a quartz oscillator, a frequency divider that allows receiving low-frequency signals of precise time, and a pulse counter. In the case of an analogue display, the signal is fed to a synchronous electric motor that moves the second hand, and in the case of a digital display, it is fed to a processor, which processes the signal and transmits control commands to the liquid crystal display. The energy source for running a quartz watch can be a battery, an automatic winding system (Kinetic in Seiko watches or Autoquartz in Swiss watches) and a solar cell (Eco-Drive in Citizen watches).

Mechanical watches operate from the energy of a wound spring, which is transmitted to the hands through a gear transmission and escapement mechanism. They are divided into mechanical watches with manual winding and mechanical watches with automatic winding.
-In hand-wound watches, winding is accomplished by twisting a spring located in the mechanism. The average power reserve of these watches is 36 hours.
-A self-winding watch has a weight that rotates the winding mechanism when the watch is worn. When wearing a self-winding watch for eight hours a day, as a rule, there are no problems with stopping it, but the self-winding system significantly increases the thickness of the mechanism. There are 2 types of automatic watches - those that can additionally be wound manually and, accordingly, with which this cannot be done. Here everything depends solely on the manufacturer and type of mechanism

Accuracy of the mechanisms.
Mechanical watches are much inferior to quartz watches in terms of accuracy (1st class accuracy of mechanical watches - from +40 to -20 seconds per day; the error of quartz watches is within 3-20 seconds per month depending on the watch manufacturer, Seiko, for example, stated 3 seconds). This is due to the fact that mechanical watches are influenced by various factors: temperature, wear of parts, adjustment, etc., the frequency of the quartz oscillator is practically independent of external conditions.

2. Housing material.

A very important characteristic of a watch is the material from which it is made. The watch may have a case and bracelet made of the following materials:

Plastic is an inexpensive and durable material. Used in watches from the cheapest to the most prestigious (heavy-duty polymer plastic Corian in Cream models from Dolce & Gabbana). Physiologically almost harmless. The ability of plastics to absorb shock is used in Casio's G-Shock watches. As practice shows, watches made of plastic sometimes look very beautiful and are immune to shock.

Zinc-aluminum alloy is a fairly light and soft material. Watches made from it wear out quickly and are easily scratched. Inexpensive technology for producing watch cases is the only advantage of this material. A protective coating is required for these enclosures.

Brass is an alloy of copper and zinc. This is a high-quality watch material with high strength and hardness. Brass is less durable than steel, which means it is susceptible to scratches. This material also oxidizes in air and quickly corrodes when interacting with the wrist, leaving black marks. Brass watches are covered with a protective coating. The popularity of brass is explained by its relative cheapness.

Stainless steel is an alloy of iron and carbon with the addition of chromium and nickel. The high strength and corrosion resistance of stainless steel make this material one of the best for use in watches. The steel used to make watches is hypoallergenic; such watches do not cause skin irritation. There is also a minus: steel cases and bracelets become scratched after some time, but this is not a problem - just polish the case. It is the steel case that has the optimal price-quality ratio.

Titanium. Titanium itself is quite fragile, but ductile titanium alloys are used to make watches. This lightweight and durable material does not require coatings, because... it is hypoallergenic. The low thermal conductivity of titanium gives a “warmth” effect when in contact with the watch. Most titanium watches have a specific matte gray color. Polished titanium is almost indistinguishable from steel, but it is much lighter. The disadvantage of watches made from this alloy is small surface scratches that easily appear on the case and bracelet.

Ceramics is a hard alloy based on tungsten and titanium carbides, used for the manufacture of drill bits. The first to use this material in the manufacture of cases and bracelets was Rado in 1962, releasing the DiaStar model. Tungsten carbide is very resistant to scratches and wear. Among its negative qualities is its heavy weight. In addition to the mentioned Rado, other companies also produce tungsten carbide watches.

Precious materials are not discussed in this text.

3. Glass

A watch glass is a transparent cover that protects the dial and watch mechanism (in the case of a transparent back cover) from external factors: moisture, dust, etc. Watch glasses can be of three types:

Plastic glass (light and transparent plastic)
-mineral glass (similar to window glass)
-sapphire glass (artificial sapphire obtained by high-temperature processing of crystallized aluminum oxide)

There are also combined glasses consisting of mineral and sapphire glasses. The Japanese company Seiko produces Sapphlex watches, in which the mineral glass is coated with synthetic sapphire. In quality they are not inferior to sapphire crystals, but in price they are noticeably superior.

Obviously, plastic glass is the cheapest. You can't break such glass, but you can easily scratch it, however, it can be polished just as easily. As a rule, it is used in sports watches with a plastic case, as well as in inexpensive watches.

Even after tempering, mineral glass will still crack more quickly than plastic glass. It can be scratched by metal objects. There are so-called high-strength mineral glasses. They are coated with a hard coating, which makes them more resistant to mechanical damage. This type of glass is available in inexpensive and mid-price watches.

Sapphire glass is the most expensive and most scratch-resistant. It has a hardness of 9 on the relative Mohs scale, second only to diamond with a hardness of 10. The use of expensive tools in processing these glasses is one of the reasons for their relatively high cost. However, the hardness of such glass makes it brittle and breaks more easily than plastic or mineral glass. It is impossible to distinguish mineral and sapphire glass by eye: they look almost the same. All high-end watches must have sapphire crystal.

4. Coating
The coating on various watch elements performs two functions: decorative and protective. It gives watches made from materials such as brass and aluminum alloy a more attractive appearance, and also protects them from environmental influences (air, sweat) and other factors. Let's look at the main watch covers:

Nickel. Being relatively cheap, it adheres well to other metals. Typically used as a midlayer due to its allergenic properties. Only nickel plating is used in cheap watches.

Chromium. It is similar in color to nickel and also has strong adhesion to other metals. Chrome plating is used in the production of inexpensive watches.

Titanium nitride. Very durable coating. Can be used as an undercoat before gold plating. This coating not only does not wear off for a long time, but also, due to its hardness, protects the case from scratches.

Titanium carbide. In terms of strength and durability, it is very close to titanium nitride, but has a black color, slightly reminiscent of the color of weapon steel.

There are other coating materials, for example, ceramic - which is as durable and scratch-resistant as titanium coatings.

Unfortunately, any coating wears out sooner or later.

Two factors have a very strong influence on the durability of the coating:
1. Leather clothing - reduces the service life of the coating by 2 times
2. Acidity of the watch owner's sweat.

5. Waterproof

The term sealed or waterproof watch means that all connections in this watch are protected by special seals that prevent the penetration of moisture. The fully threaded screw-down caseback with O-ring seal and the screw-down crown greatly enhance the watch's water resistance.

Water resistance depends on many factors, such as the design and quality of the case, the thickness of the glass, the material of the seals, the load on the watch, fluctuations in ambient temperature, etc. The tightness of a watch is not a permanent property and is lost over time due to the natural wear and tear of the seals.

Be careful, in reality there is nothing in common between real meters and those indicated on the dial or case back. These figures correspond to the ideal (laboratory) conditions under which the water resistance test took place. When swimming on the surface of the water, hitting the water with your hand creates pressure that the watch may not be designed to withstand. And even a shower jet can create pressure much higher than 3 atmospheres.

The water resistance chart for most watch manufacturers is as follows:

Sealed watch (3atm):

If “Water Resistant” or “Water Resistant 30m” is engraved on the base of the case, the watch is designed and manufactured to withstand pressure up to 3 ATM (minimum degree of water resistance). Occasional contact with liquid will not harm the watch (rain, drops of water when washing hands), but it is not intended for swimming, immersion in liquid or showering.

Sealed watch (5 atm):

This position is the most controversial. Although manufacturers claim that you can swim in watches with such markings, most sellers and service workers still DO NOT RECOMMEND this!
So, if the inscription “Water Resistant 50m” is engraved on the base of the case, then this means that the watch is designed and manufactured to withstand pressure up to 5 atm. Such a watch must withstand the penetration of sweat, rain, drops of water when washing hands, and also withstand short-term (accidental) immersion in water.

Sealed watch (10 atm.):

If “Water Resistant 100m” is engraved on the base of the case, the watch is designed and manufactured to withstand pressure of 10 atm. This watch is suitable for water sports, but it is not intended for scuba diving. After being in sea water, the watch should be washed in fresh water and dried. Do not operate the winding mechanism in water.

Sealed watch (20 atm.):

Watches marked “Water Resistant 200m” or higher on the case can be used for scuba diving, but for no more than 2 (two) hours.

Pressure expressed in atmospheres (1 atm - 20 atm) should not be considered as equivalent to the depth of immersion in water. When diving, movements made at a constant depth increase the pressure on the watch.

6. Backlight
The backlight in the watch is designed to make it easier to read the time in the dark. In modern watches, the backlight is based on the phenomenon of luminescence and semiconductor technologies.

Luminescence is the “cold” glow of a substance. There are several types of luminescence used in watches: photoluminescence, radioluminescence and electroluminescence.

Super-LumiNova and LumiBrite are photoluminescent paints applied to watch indexes and hands that are completely harmless to humans and the environment and do not contain harmful materials such as radioactive substances. They have a relatively long afterglow after a short charge in the light, however, over time the intensity of the glow decreases. The duration of the glow period depends on factors such as: the brightness of the place where the watch is exposed to light, the distance between the light source and the watch. If the wristwatch, as is usually the case, is covered with a sleeve of clothing, then the luminescent layer will not receive the necessary recharge.

Coatings based on radioactive isotopes of tritium and promethium are now used as often as photoluminescent paints. They fully comply with the international standards ISO 3157 and NIHS 97-10, which define the minimum amount of luminescent substance required to see the dial in the dark. True, more dangerous phosphors were used before - for example, radium in Radomir watches from Panerai, but they were abandoned long ago. The radiation emitted by this coating is completely absorbed by the watch case and glass. Swiss manufacturers put the inscriptions T-Swiss-T and Swiss-T on the dial of such watches
Many sports watches, such as Casio, have electroluminescent backlight, LED backlight and micro backlight, which are based on semiconductor technology. This is an ideal backlight for dials, but it is only used in quartz watches.

7. Strap (this factor is also important, although, unlike others, it can be replaced).
It all depends on what is more convenient for you.
-The bracelet is much more durable, reliable and durable. And heavy...
-The belt is more aesthetic, although this is a controversial statement - each person has his own opinion on this matter. The belt is lighter, softer and more pleasant to the touch. But not as durable as the bracelet.

Some models come only on a belt or only on a bracelet. Depending on the whim of the designer who created this model. And when replacing a bracelet with a belt (or vice versa), much of the appeal of a particular watch model is often lost. In addition, such a replacement is not always possible from a purely technical point of view.

Higuchi sells Japanese watches from his domestic collection (for the Japanese market). As a rule, the Japanese produce watches for domestic consumption in Japan (but there are exceptions).
And Higuchi is a guy who has been tested by dozens of buyers from Russia. Even if the model is not on his website, you can just look at http://www.seiko-watch.co.jp/lineup/ watch, write what you want, he will answer and name the price.

American stores:

All US states provide for criminal liability for the sale of non-original products through retail chains.
Thus, there are quite strict control mechanisms over the products sold.
However, of course, it is still better to buy from trusted watch stores that make several thousand sales a day. And it’s better to buy from their representatives on ebay if you don’t want to buy directly from the store.
