Quartz Wrist Watch: how they work, how to choose

Today, quartz watch - this trend of our time, a bastion of reliability and practicality of the guarantor.

Basis quartz mechanism oscillatory system - quartz crystal, and the power source - battery which generates continuous vibration of the crystal, when the voltage fluctuation electronics captures and measures a second (1 second = 32768 Hz).

Engine, taking electrical impulses that gets wheeled mechanism which controls the movement of the clock hands. Due to the precise supply of electrical impulses, quartz clock shows the correct time.

Amendments are made to the time displayed by them only once every six months. Over time, the quartz crystal starts "were aged" and is strongly reflected in the arrangements - they will either hasten or lag.

How do Quartz Wrist Watch

internal structure

At the heart of electronic quartz watches - quartz crystal. This microscopic stone:

• right Stepping electronic motor, which moves the arrow;
• It lets you know the electronic unit that was another mikroperiod.

As for the mechanical part, it will last a long time, since the small-numbered gears not feel the DC resistance of twisted springs, and the load on them short-term.

Due to the reduced load on the moving parts, accessories manufacturers produce modern weightless plastics. This makes it possible to reduce the weight of the device and increase battery life. Thus, the problem of electronic stepper motor simplifies many times.

Quartz watches are hypersensitive to the ingress of water into the hull. To prevent the fault or malfunction, you need to carefully monitor the work of the seals (gaskets) and time to be replaced by new ones.

Even unpretentious model considered shockproof.

Battery

The energy source - a battery, feeding electronic unit and an electronic stepper motor. battery charge lasts for 5 years, after which there is a replacement.

Price

Mechanical Wrist Watch - an object of prestige, therefore, they are much more expensive than quartz. This is due to the fact that the mechanical demand painstaking manual assembly, when quartz is automated.

Advantages and disadvantages

• Availability - mechanisms such accessories are collected largely without human intervention.
• Practicality - at the expense of a tiny mechanism, the product is almost weightless. They are no parts that are sensitive to external influences.
• Accuracy - uncertainty in time of +/- 20 seconds per month.
• Working properly - Use a small number of mechanisms, which guarantee smooth operation.
• Resistance to deformation - hitting on a hard surface, the work will not stop mechanisms, and by coating the dial, the appearance will not change.
• They do not require that the plant - mechanisms will not stop until until the batteries have expired. Battery life - 5 years. Today, most models cost battery, has worked for 10 years.

Quartz watches on par with the classic method is the use of a digital representation of the screen:

• there is a display of the current date and time;
• the owner receives the results of their calculations and statistical data;
• the device measures the parameters determining the weather conditions and weather forecasts based on them;
• the owner is working with organizer and service that supports the same time on the network servers;
• thanks to built-in memory, the owner doing anything with the information provided.

The only drawback - low maintainability. Due to the automated assembly is difficult to manually replace the faulty part. Easier to buy a new product because of its cost, quality and reliability ensures long use in appropriate care for them.

How to Choose a Quartz Wrist Watch

The choice of a wrist accessory recommended for the following parameters.

Style - appearance chosen based on an image and a person's style. Universal version - classic.

Color - adjusted for your colors and images.

housing material - is considered durable casing made of titanium alloy or stainless steel, and if plastic, then it is better to choose the brand-name manufacturers.

We do not recommend to buy:

• Aluminum - robust enough;
• Nickel - dangerous to health;
• gold-plated - with gilding coming years and that leads to modestly mind.

material of the dial - organic glass (PMMA), crystal and sapphire crystal.

The shape and size - circle, square, rectangle or oval. When buying a wrist size is taken into account.

Glass:

• plastic - will stand before the appearance of small scratches;
• mineral - is able to resist deep scratches;
• Sapphire - the most reliable.

backlight:

• Fluorescent - svetonakopitelnye composition is applied to the elements of the dial and provides backlighting after momentary Spent light;
• EL - a bright and intense lights activated when the button is pressed;
• LED - light in the form of energy-intensive flashlight small in size;
• tritium - an advanced and technically sophisticated lighting of choice for those who value battery life.

Additional functions - alarm clock, stopwatch, calendar, impact resistance, water resistance and precision.

Exploitation

Before proceeding with the installation time / date, turn the crown a few times counterclockwise, and loosen the thread, which is used for fixing this crown. If you need to return the crown to its original state, you must first push the crown to the stop, then defeating the resistance of the spring thread tighten clockwise.

On the dial, days of the week are displayed as: MON, TUE, WED, THU, FRI, SAT, and SUN.

Quartz watches have a stopwatch function (chronograph), which measures the time intervals.

Start the stopwatch - press the "A" button.

Disable timer - press again the "A".

Reset the results - the button "B". If in the process of resetting the chronograph hand is not returned to the position of number "12", it indicates that the value of the shot down.

How to adjust the chronograph:

• put the crown to position III;
• press "A";
• wait when the arrow will make turn and lock around the number "12".

After spending adjustments, chronograph hand after resetting will automatically return to "12".

Precautions waterproof models

If a wristwatch worth marking WR, the meaning that they do not absorb and do not pass through the water itself. Water-resistance is guaranteed by spacers, which are screwed crown.

Therefore, they banned from visiting the sauna, swim in the shower, swim and dive into the water.

Manufacturers produce special watches for divers. In these models the water resistance of 300m WR and more. This means that you can swim in them, above all under the water, do not unscrew the crown. If it is unscrewed, the water gets into the body and cause damage to the mechanism.

If you have a stopwatch, then use it under water is prohibited because the water enters through the side button chronograph.

Manufacturers recommend to rinse after swimming hours in clean running water.

Care

Clock cleaned regularly with a soft material, except for the leather strap. Before you begin to rub, cloth moistened with warm soapy water, and then wipe dry wipe product.

Keep the product is desirable in the box in which they were sold.

Broken or cracked glass necessarily replace, or dust particles hitting the device did not give chronometers show the correct time.

It is not recommended to sleep with the clock, because in a dream, we do not control traffic, and can inadvertently damage them.

We should not leave the device in places that are subject to strong temperature fluctuations, in the sun and near the sources of the magnetic field - it's definitely lead to malfunctions.

malfunctions

Since each model has its own design feature and have different properties, it is sometimes necessary to hold them or prevention or repair.

Master identify several major types of faults which lead to an incorrect display of time, failure of the mechanism, the stop hour, minute and second hands:

• contact oxidation;
• low battery power;
• radial touch the arrow on the glass enclosure;
• damage or breach mechanism which is caused by mechanical means.

This is not the whole list of problems that may arise. Each holder of such a product necessarily faces problems that he can not understand. In this case, it has several options to solve them:

• disassemble itself and result in inadequate internal mechanism due to ignorance;
• to pay for the repair of the first that fell "master" at minimal cost and without guarantees;
• to find a really good master and to pay him;
• throw it away and buy a new product.

If someone watches - this is the famous phrase of gloves, you do not worry at all. But for some people, they mean a lot, because the price of accessories can reach the value of the car. Here is just come to the aid of a professional service center, who repairs watches and works with all models.

Watchmaker when you conduct a comprehensive diagnosis and identify the cause of machinery malfunctions, then tell you on the work that must be undertaken to eliminate and report the time required to do the job.

The master has a special tool and a great amount of detail. Master repair everything from the bursting of the glass and ending with the working mechanism. However, there are situations that require the details of which can not be by private watchmakers, then the best solution would be to include the quartz watch in the professional center.

Useful tips when buying

We understand that represent a quartz wrist accessories. Found out the pros and cons. And now dwell on the points relating to the purchase itself:

• Purchase only from reputable manufacturers, as they watch the reputation of its brand.
• Pay attention to the warranty - it should be not less than one year
• Take the check, because if you have something does not suit or a warranty case occurs, it always need.
