Device electronic wristwatch
Electronic wristwatch device called a quartz oscillator and a digital display for displaying information. Generator, whose work touched quartz sends pulses at regular intervals. These pulses are used for counting seconds and synchronizing the display of numbers on the screen.
In hybrid devices to display the information is combined with the usual dial micrometer.
Electronics is less subject to the influence of the environment and undemanding in operation.
Apart from price, accuracy and reliability, electronic watch draws additional features:
- Displays the current date;
- built-in calculator;
- cameras and camcorders;
- temperature, humidity, pressure;
- pedometer;
- the ability to connect to a personal computer;
- Shows the user medical records.
The latest models of «smart watch» resembles a small laptop computer. They are able to connect to the Internet via WIFI and download applications.
There are lineups focused on specialized user - it's athletes, tourists, hunters.
For fishermen and lovers of mountain recreation fit models with built-in barometer, and for athletes in them embed meters and pulse pressure, pedometers.
How to choose the electronic wrist watch
Choosing electronic wrist watch, prefer expensive models of well-known manufacturers. They last longer and safer than a cheap knockoff. In addition, conscientious manufacturers offer a guarantee on products.
Business men prefer the classic model shapes and sizes. It is a round, square or rectangular body. Low-key color, often in dark colors. Such products fit in style to a business suit and looking at the hand naturally.
Oval or irregular shape preferred by teenagers. They like bright colors, unusual shapes and additional features, such as games or internet connection.
By the choice of women's watches have a thorough approach. Every woman should have a few models in different shapes and colors. Appearance and color of women's products should be combined with a variety of dresses from the wardrobe.
When purchasing female models focuses on weight and how they look on the hand.
Large and massive clock will look ridiculous on thin and graceful woman's hand. Small watch on broad wrists will hand more visually. Therefore, large ladies better to buy mid-size model.
Athletes are oriented not on form, color and appearance, and functionality. The most important parameter of a wristwatch for the athlete - is the weight of the product. Weighted affects the internal structure and the material of the housing. Plastic housings easier, but less durable. Products in the metal case may be severe.
Better to buy a lighter model, because the product weighing over a hundred grams can cause discomfort during extended wear. And with active exercise can cause problems with the wrist.
When choosing a watch, should make sure that the back cover has a slightly curved surface in all directions. This form of conveniently fits on the wrist and does not cause discomfort.
Pay attention to quality, reliability, and body strap, the average life of the batteries. In some models, the battery hidden in a non-separable housings, replacement batteries are not available - they are one-off models.
housing
Pay attention to the quality and material of the body. Impact-resistant and high-quality models are executed in titanium alloy housings.
The metal is not subject to change under the influence of the environment and contact with human skin. These models have a rigid structure and good mechanical impact.
If you expect a long service life, do not buy products Wrist with gold or silver-plated body. With long-term use of spraying necessarily oblezet and spoil the appearance.
This rule holds true for inlaid inserts, stones and other decorative elements. They are attached to the body with glue and may eventually break.
Features glasses. Plastic glasses are easily scratched, but also easy to be polished.
Mineral glass, are used more frequently, scratches appear less often. To scratch a glass, you need contact with a very hard object. Mineral glass break is difficult - more damage the body.
After several years of sloppy socks glass can get scratched. Polished mineral glass on the clock is expensive, and not every shop provides such services.
The best way to protect the dial and LCD display from damage - sapphire crystal. Scratch it under normal circumstances is not possible - only when exposed to a material that is harder than sapphire.
Strap
The straps are made of genuine and artificial leather almost indistinguishable to the eye. Both materials give hours classic look. They are flexible and soft, good to keep on hand. They can make extra holes to adjust the strap to the hand of the owner.
However, we should remember that skin and leather wear out quickly with an active lifestyle and acquires the form, not suitable for carrying.
The strap of a plastic nylon or silicone - soft and flexible, waterproof material, mainly used for sports watches.
plastic straps compared with the skin, nylon and silicone, have a rigid structure and may be worn or scratched. For the price - this is the cheapest option, but also the most fragile.
metal straps It consists of units connected by special fasteners. They are easily fitted to the arm by removing unnecessary links. metal belt can be different: stainless steel, silver, gold, platinum. The more expensive metal, so it looks elegant on his arm.
Metal straps are heavy, so not suitable for athletes and children.
prevention
For reliable and long-term operation, electronic and mechanical watches are given for routine prophylaxis master every two to three years. They are cleaned in ultrasonic cuvettes, being replaced water protection pads.
Battery replacement is carried out every 3-5 years, depending on the battery condition. Not recommended for models with solar panels and kinetic eyeliner, if you want the device to last a long time.
Such mechanisms are much more difficult and expensive to replace in case of failure. The service life of the battery up to 7 years in ideal conditions.
Exploitation
To watch served reliably for decades, adhere to the rules of operation, the following:
- Before use, carefully read the instruction manual. Ignoring the rules of operation fraught with constant breakdowns and unforeseen problems;
- Do not expose to strong overheating or overcooling. Do not leave in direct sunlight or open sources of heat, this also applies to hypothermia. Changes in temperature adversely affect the operation of mechanical and electronic clock;
- Do not expose the strong electromagnetic radiation (magnetization mechanical pendulum clock lead to complete failure);
- For an active lifestyle and sport select special models designed for additional loads;
- Periodically change your battery. contact oxidation can damage the circuit board and damage the unit;
- As a yardstick for the prevention of not less than once every 4-6 years;
Problems
Common problems are caused by discharging the battery - decides to replace the batteries.
A common problem - the problem with the chip, the receiving frequency pulse generator. In this case repair is not always possible. It is necessary to test the state of the chip, and breakage detection complexity. The problem lies in the fact that the need to repair the original chip, which is hard to get.
generator itself can be broken only when a strong impact. The quartz crystal is almost impossible to break. But even if that happens, find and replace this part is much easier than chip. And it's worth much cheaper.
Output
Electronic watches are reliable, easy to use, even for children who find it difficult to understand the testimony of the shooter. Once set the date and time, you can enjoy them for a long time.
Additional features are useful for people who lead an active lifestyle. Increasingly, such devices chosen by men, who value precision and reliability. Every year there are new hours and new features that can make life easier.
