20 general knowledge about watches collected over the years! Playing with watches must be good for you?

1. Styles and Functions of Watches

Watch styles and functions, watch separator

Mechanical watches and quartz watches two categories, the most common mechanical watches, the function is automatic calendar.

2.Quartz watches and mechanical watches

Which is better, quartz watch or mechanical watch? There should be good and bad, not divided into value, quartz watches are also expensive. Mechanical watches are also cheap. Generally speaking, mechanical watches are more ornamental, quartz watches have high precision and are easy to use. There are three ways to distinguish them. (1) look at the logo, automatic watches will have automatic letters, or automatic winding letters, (2) look at the second hand movement. TUDOR Black Bay Chrono M79360N-0002It is a quartz watch with minutes and seconds jumping, and a mechanical watch with a second hand constantly crossing the disk. (3) Whether it can be wound or has the sound of automatic rotation.

3. Indication function of the watch

The hands work together with the dial to indicate the time. There are also windows that use numbers. Window-type multi-purpose calendar. The so-called "large calendar" is two windows that show ten and your date.

4. Flyback and retrograde forms of the watch hand

Not a clockwise direction of the circle, fly back is a chronograph for zeroing characteristics, while the retrograde is in the watch needle to go "fan-shaped". Walking fan-shaped retrograde is more strange, it is automatically managed to zero after walking a full course.

5. Chronograph function watches

Commonly known as "three hands and three eyes", there are three watch handles. 1. Most stopwatches currently use a two-button model, the two buttons are usually in the 2 position and 4 o'clock position. 2 o'clock button to control the "start and stop" function, the 4 o'clock button to control the "zero" function. 2 o'clock button to control the "start and stop" function, the 4 o'clock button to control the "zero" function. "The method of operation used is usually a "start-stop-zero" or "start-stop-zero" process. You must press the reset button before stopping the stopwatch function.3. Single button stopwatches are simpler, TUDOR Royal M28500-0006 with a single button that controls the "start-stop-zero" function. Please note that each time you press the button, you must wait until the button is reset before pressing it again.

6. Moon Phase Display

The phases of the moon are actually the lunar calendar, indicating the cycles of the moon's deficits. The sun, moon and stars are the most visualized celestial bodies, but the moon phase is related to latitude. Design Principle:The moon phase function is often placed in a semi-circular window with a special shape, including a semi-circular arc and two small arcs. This elaborate shape, combined with the moon on the moon phase disk, tells us more accurately the shape of the moon at the beginning or end of a cycle. Principle of Operation:The moon phase displays the state of the moon on a lunar disk according to a cycle of 29.5 days. This moon phase disk has two moons with 59 teeth on the sides. The moon wheel is driven by a drive wheel and advances by one tooth per day, at which time the changes in the moon's phases can be displayed on the dial in time. 59 teeth of the moon wheel come from the average of the moon's phases every 29.5 days. Because the moon's precise rotation period is 28 days, 12 hours, 44 minutes and 2.9 seconds, the moon phase display has an error of 24 hours every 33 months. There is usually a push-button on the case to adjust the moon phases,TUDOR Royal M28503-0008 and the moon phase display is relatively independent of the chronograph and perpetual calendar functions.

7. Winding Power Indication

Indicates the state of the watch's windings, similar to an automobile fuel gauge. Long power watches are generally more than 72 hours, generally 7-10 days, the longest one month. Long-power watches have a large number of winding boxes or very long windings. This function is more useful.

8. Perpetual calendar watches

Perpetual calendar is one of the three major complications of watches, which has been very mature in the era of ancient pocket watches. The basic principle to realize the perpetual calendar is to design the April gear (also called 48-tooth program gear) in accordance with the 4-year 48-month leap year cycle, and to realize the jumps of the big and small months and the flat leap years through the mesh cooperation between the gears.

9. Tourbillon

Commonly known as "ghost push mill", tourbillon table represents the highest level of management in the mechanical watch manufacturing technology process, the entire escapement speed control mechanism can be combined together to learn and we are able to rotate to a certain speed development of continuous rotation, so that it will be the gravitational force of the mechanical watch "escapement System" in the mechanical watch to minimize the risk of the impact of gravity on the "escapement system" to improve the accuracy of their timekeeping data. Due to its unique operation mode, the dynamic artistic beauty of the watch has been played to the highest level, and it has always been known as the "king of the watch".

10. Spherical Tourbillon

Jaeger-LeCoultre's top spherical three-dimensional tourbillon, spherical tourbillon will be the watch escapement regulator wrapped in two frames, double frame were running along different axes. Precision rotation mechanism as if measuring the celestial body of the armillary sphere in general, can be said to be the most ornamental tourbillon!

11. Watch Hands and Disks

High-quality watches generally use blue steel hands. Watch hands come in many shapes, but they have names and traditions. They are the famous "Breguet" hands. The hands of sports watches are usually in the shape of rods, and in flight or military use they are often in the shape of swords. Louis 15 and Louis 16 hands are basically used in clocks and pocket watches.

12. The three defense functions of the watch

Waterproof function, a qualified watch must be sealed to resist 3 atmospheric pressure. WATERPROOF LETTER MARKING WATCHES: On the back cover of a WATERRESISTANT, there is usually a waterproof rating, atmospheric pressure is considered to be waterproof for life. There are several ways to indicate (1) water depth, such as 30M, and (2) pressure: write 3ATM or 3BAR. deep dive pressure watches, visible can have 600 meters, many watches waterproof value is a blind spot, can not believe.

13. Regular dive watch characteristics

The so-called dive watch, as the name suggests, refers to: diving timepieces (waterproof and moisture-proof for divers to use the watch). Ordinary waterproof watches cannot be used for diving. Diving watches must comply with strict regulations and do not have to be waterproof to be called diving watches. Simply put: Diving watches should have higher water resistance, luminescent hands and scales that make it easy to read the time under the sea in the dark. The role of the dive watch is as follows:1. Anti-corrosion flexible strap. Screw-in non-slip crown. Three rows of helium.4 Luminous indications.5 Rotating bezel.

14. Anti-magnetic watches

High anti-magnetic watches are very useful. Watches can be easily magnetized, causing the business to suddenly go faster for several minutes a day. Comprehensive demagnetization is done by professional students. Anti-magnetic English literature identification: ANTI-MAGNETIC. green glass Rolex, also known as the "flashing needle" anti-magnetic 1000 gauss, high anti-magnetic watch is used a soft body screen cover, wrapped movement. The latest development of technology is not magnetic technology, such as Omega's 15,000 + gauss.

15. Deep Diving Watches

Deep-diving watches have a thick case, made of titanium, and a thick glass. The record-breaking watch is made by Rolex, over 10,000 meters, and the watch glass is a hemisphere.

16. Watches certified by chronometers

After rigorous testing and qualification of the watch, you can mark the chronometer certification, the letters identified as: CHRONOMETER, generally 6 o'clock position on the dial. Rolex, Omega watches, many of them. There are also some lower grade watches available. Three degrees. A combined test in five positions. Abbreviation COSC.

17. The most common problem with wearing an automatic watch.

The timekeeping appears to have a large error. The length of time and the lack of time, stop watch. Watch automatic and waterproof is the most likely to lead to some ambiguity, look at the meaning of the word. Insufficient level of movement at this time, it is necessary to make up the string on the hand.

18. Calendar hand of the restricted area problem

Nowadays, the hands of the watch can basically be reversed. Quickly dialing the calendar when you need to confirm the time of the hands, in the calendar mechanism should be avoided when the work of the quick dial calendar. The same is true for functions such as weekly and monthly calendars and months.

Smartwatch Emergency Watches

Some watches fall into the category of cell phone peripherals. Radio watches or satellite watches have functions such as timing, positioning, height measurement, etc. Emergency watches are usually worn by military and special forces commandos and can transmit a 121.5 MHZ signal with a reception range of 20 kilometers.

20. Watchband

Watch band material for application research a lot, the basic points of metal and leather. Precious metal is commonly 18K gold, leather enterprise best is crocodile skin. Now tungsten steel, rubber, ceramic, silk fabrics are also very common. The watch band is an important part of the watch composition, the value of the investment ratio is also not low, the form and color design of the watch band to be with the Chinese watch can match.
