Shock watches: the characteristics of the device

More recently, wristwatches were considered a luxury, which could afford only wealthy people.

With accessories, please check very carefully, because the fragile and expensive construction was easily damaged. Fortunately, it is now in the past. Modern technology made significant progress in improving the movement, increase strength and durability.

Chips and scratches housing for everyday wear does not cause inconvenience: shock watches have been established for regular stay in an extreme situation. They will be the best one for athletes, hikers, hunters and fishermen - those who want to make sure that even in the harshest conditions technique fails.

impact standards

Shock watches is considered the model, the mechanism of which is capable of undergoing physical impact without damage to the precision work and appearance.

Unfamiliar with the specifics of the product, the user can assume that the marking "shock", indicated in the passport, mechanism ensures resistance to different stress intensity, such as a strong pressure shock or the fall.

Practice has shown the fallacy of such reasoning as shockproof called instances that meet international standards. He makes the product the minimum requirements, compliance with which is verified experimentally.

The device is considered to have passed the test with the following requirements:

• The clock does not stop working in the event of an impact from above or from the side.
• Accuracy daily for accuracy of the quartz due to impact is less than two seconds. For other types of error is considered normal in 60 seconds a day.
• When external examination after the fall is not detected serious damage to a cosmetic nature, shifting elements.

Apparatus shockproof wristwatch

Shock protection is provided hours frangible elements during impact. Characteristically, for mechanical and quartz devices to protect technology from damage is not the same because of differences in the structure and operating principles.

Mechanical models are equipped with "parachute" spring that absorbs shock as open the parachute man throws up and then allows you to control the landing.

Thus, a floating arrangement which protects against impacts. In addition, eliminating the need to further trim parts cushioning coatings, which saves space and reduces the weight of the product.

Mechanical products are complex from a technical point of view, the mechanism, the details of which are subject to constant contact pressure. Provide him with the strength of quartz is not possible because of design features.

Housing shockproof watches

Housing is an element of design, which should be given maximum attention when choosing a product. Significant are the external structure and the material. The geometry of the body varies depending on the strength requirements for the module.

Thus, a concave structure with protruding rim and prevents contact with the display surface of the flat keys. In other words, provided complete protection against free fall irrespective of the angle orientation.

housing material

When choosing a sports watch sailing enthusiasts prefer models made of titanium. Devices of this material is not susceptible to magnetization, hypoallergenic.

Furthermore, they have low thermal conductivity and hence less susceptible to heating and cooling, which provides comfort when the article is worn. The housing heats up to body temperature and does not feel on the hand. The negative side of a titanium body is considered to ease the appearance of surface scratches.

No less popular for body shock-resistant watches material is plastic, capable of absorbing an impact against a hard surface. It performs a damper function, protecting the quartz oscillator in the module.

Common practice, when large firms are developing an original composition of the plastic, after registering a patent.

On bezel devices also possible to apply a coating of protective material such as urethane rubber. Thanks to her, carried out the protection of vulnerable parts of the product from mechanical damage. If the clock drops a heavy object, the bezel will assume the force of impact, preventing damage to the dial.

Glass shockproof wristwatch: material, shape and coating

Glass provides protection, but also becomes an element of decor, decorating the dial. Manufacturers pay attention to him, because that's the first thing you notice about a person by looking at the device.

Lenses different raw materials of which are made, and configuration. On the market there are three main varieties of materials used in production: Plastic, organic (mineral) and sapphire crystal. It is advisable to consider each type separately.

Glass, plastic not installed on machines with shockproof design because of its fragility. This is the cheapest material, suitable for low-end models of watches. Strictly speaking, this is not glass, and plastic surfaces.

mineral glass, Otherwise known as Crystal glass, it is characterized by an optimal price-performance ratio. Impact resistance of this material is higher than that of sapphire, although it is less solid. In other words, it is not easy to break, but you can leave a scratch.

Provision has also hardened mineral glass, which is more complicated incised.

Sapphire crystal, made of synthetic sapphire, characterized by the same features as natural stone: hardness and transparency. Scratch it is only possible high density cutter, for example, made of diamond.

Sapphire lens is installed on the flagship model or design as well as shockproof waterproof watch. Although visually it does not differ from the mineral, it is much easier to break, and when striking it shatters into small fragments.

The geometry of the glass unit due to the specialization. Convex glass installed on the sport model with a large dial. They are characterized by increased thickness, which results in impact resistance. Another advantage of the spherical surface can be considered as a slight increase in the size indicators on the dial.

Flat glass is more widespread, they are easy to replace and manufacturing. Completed most of the mineral or sapphire material, they have high strength and protect the mechanism from damage.

The coating applied to the surface of the lens shockproof hours chosen depending on the problems arising during operation.

It fills the irregularities of the lens, preventing it from sticking to the particles of dust and dirt.

Verify the presence of water-repellent coatings may be looking at the dial after it hits the water droplets. If the surface is left streaks and spots, the coating is present.

Anti-reflection coating prevents the increase in the number of light reflections at the lens surface. When this mirror effect is completely eliminated. The coating is applied to one side surface or on both.

An improved version is represented by a lens consisting of the antiglare structure. Unlike deposited on the surface, built-in cover is not erased with time, maintaining their properties.

Water-resistant shockproof watches

Prevent water from entering the mechanism of the device is necessary to engage in mobile water sports without fear of permanently withdraw watches fail. To indicate this function is used abbreviation WR, which is applied to the dial or back cover.

If engraving, indicating waterproofing product is not available, then the device should avoid contact with moisture.

The principal values ​​of water resistance:

• WR - so marked articles capable of withstanding a short contact with the liquid that occurs during hand washing or contact with device raindrops. Models for everyday wear have this marking.
• WR50 - this mark labeled model with a relatively high degree of water resistance. It allows the owner, without removing the device from the wrist, take a shower, wash their hands, and even swim but not dive.
• WR100 - this inscription says on the admissibility of complete immersion in water, but do not wear products in the pool or sea. Under these conditions restrain ingress of liquid into the housing becomes complicated due to the extra load in the form of moving waves.
• WR200 - this marking placed on the product for divers. The configuration of the housing parts to ensure the integrity and stability of running even when diving. This design implies the presence of a special valve which regulates the internal pressure of the device.

Water-resistant enclosure decreases over time due to wear pads. It should be every 2-3 years to check the device in the cabin for leaks.

Backlight on shockproof wristwatch

All sports watches in one way or another provide clarity dial indicators in conditions of poor visibility. To perform this function, the following types of luminescence:

Photoluminescent bright lights manifests itself immediately after the charge in the light, then gradually losing its brightness without light exposure in one form or another.

Tritium luminescence dial illuminates in daylight conditions and in darkness. It requires no additional charge from the light source unit or the battery and less bright, in comparison with fluorescent.

EL backlight is activated by pressing a button or automatically when tilted at an angle brush. It evenly illuminates the surface of the dial.

conclusion

When choosing a product it is important to determine the order of the functions which will be required to use, but from what can be discarded.

Shockproof watch different variety of options that are useful in harsh conditions: high altitude, under water, under extreme temperature conditions. Athletes should pay attention to the availability of a chronograph that counts short intervals.

Heart rate sensor will track your heart rate and observe the dynamics with regular sports training. The thermometer will help monitor temperature changes during diving.

If you need to expand the options is not available, and priority purchase qualities are strength and reliability when selecting the best to give the value of impact resistance performance, waterproof and brightness of the backlight dial.

It will create extra cushioning product at impact, and still be the best of a tough and nice-fitting hand. The nylon strap is heated in the heat, the skin does not breathe underneath that is uncomfortable to wear.

Shockproof watch perfectly serve as a gift, as for everyone, regardless of age and occupation. Selected in accordance with the owner's needs, they become the source of his pride and pleasure.
