If anyone wants to learn all of a sudden knowledge, that is unlikely, after all, eat a big fat, more watch knowledge we need to slowly learn and explore. Today we have selected seven common watch terms, learn together.
1
Moon phase
Moon phase table, is a personality with a moon phase display watch, through the moon phase plate on the table can grasp the lunar changes in the ebb and flow. Case usually adjust the moon phase button, moon phase display and calendar and other functions are relatively independent.

Most of the moon phase tables have a curved (semicircular) small window on the dial, mostly at twelve o'clock or six o'clock, through which small crescent, winding, full moon and lower moon are displayed Phase change.
Normal moon phase watches are often calculated on the 29th of a month , and simple mechanical devices are sufficient. However, the shortcoming is that seven days a year are less than a full month in a four-year period and manual adjustment of errors is required. However, the moon phase device of the complicated function watch counts one month as 12 hours and 45 minutes on the 29th, which is only 57 seconds compared with the average time of lunar revolution, which is less than 12 minutes a year.

The best way to adjust the moon phase table is to adjust the instructions according to the instruction manual , but if there is no manual at hand, the adjustment will be based on the lunar calendar of the month of May, aligning the moon phase of the moon phase to the middle and then The lunar calendar was adjusted to do.

Fly back / retrograde
In the watch function, fly back and retrograde are often put together, the industry often use this function directly with "fly back / retrograde" to represent. However, in fact, flyback and retrograde, though functionally similar, have a completely different internal mechanical structure and working principle .
"Rebound" type pointer is to go arc, "retrograde" type of return is done automatically; and "fly back" type chronograph pointer is circling round, and its return to zero requires manual button operation, Can also be done in both directions.
Fly back to time
Flyback function dedicated to the description of a certain type of chronograph. Fly back to time, it means that press the button, all the time pointer immediately zero and immediately turn on the next time. The pointer that reaches the end is not moving forward and bounces back to the starting point immediately, turning it into a reciprocating motion.

Ordinary chronograph need to start, stop and zero these three actions to complete, equipped with a fly-back chronograph, the wearer just press the button once, that is completed at the same time to stop, reset, and restart the timer action. Not only reduces the loss due to multiple operations, but also can be quickly and accurately timed, for the wearer, convenient and "energy saving."
Reversed
Reversal as the name suggests is the pointer can jump back, is the pointer in the normal operation of the case, when the end can immediately jump back to the origin, and continue to operate normally.

Retrograde refers to the operation of the watch pointer is a way, and traditional circular pointer rotation is not the same, the retrograde needle is to take a one-way , when the indicator full scale, the pointer will instantly return to the starting point, and then repeat the new process.
The retrograde graduations are fan-shaped, and the axis of the pointer is generally on the edge of the dial. The curvature of the graduated sector is below 180 degrees, typically between 120 and 150 degrees.

Calendar
Watch with calendar function without manual adjustment, can automatically identify size month and leap year in February, always maintain the accuracy of the date.
Patek Philippe Perpetual Calendar Ref.5320G
The Gregorian calendar is 365 days a year and is divided into 12 months, of which 7 are on the 31st (January, March, May, July, August, December) and 4 are Satsuk (April, June, September and November ) Is 30 days and 1 month (February) is 28 days or 29 days (leap year). Gregorian calendar leap year to determine the rules follow: a leap for four years, a hundred years non-intercalary, re-intercalary four hundred years . Every leap year, February is 29 days.
Perpetual calendar watch is such a complicated almanac algorithm, through a number of different sizes of gear operation, calculation, and integrated into a watch case. The general perpetual calendar movement can only calculate a four-year leap, can not calculate the more complex calendar, so the general accuracy of only 2100 .

Perpetual calendar movement can be divided into two parts, one part in charge of hours, minutes and seconds of the general timing work, the other part is like a set of astronomical self-propelled mode, which operates with a miniature satellite gear system, the entire system rotation for a week It takes four years.

Tourbillon
Tourbillon Swiss watch master Louis · Baoji invented in 1795 a clock speed control device. French Tourbillon (also known as Trinidad and Tobago), a "whirlpool" meaning, is equipped with "rotary escapement speed governing mechanism" mechanical watch, tourbillon is to correct the gravity caused by the error of the watch parts.
Breguet 5439 double tourbillon watch
Tourbillon watch represents the highest level in the mechanical watch manufacturing process, the entire escapement speed control agencies together and can rotate, with a constant speed of rotation, so that its gravity on the mechanical watch "escapement" Minimize the impact and improve travel time accuracy.
How it works : The gossamer, fork lever and escapement system designed to operate in the same axis, the tourbillon will continue to rotate in operation to reduce the impact of gravity.
However, tourbillon device is extremely complex, but also because of the high cost of production and process requirements, so tourbillon has become synonymous with high-level watches.
Jaeger-LeCoultre Earth Observatory Tourbillon watch
Spherical tourbillon shape similar to the ball, spherical tourbillon is not only more visually three-dimensional, to ensure the accuracy of travel time to go a long way. Ball Tourbillon first by the Jaeger-LeCoultre in Geneva in 2004 to launch.
In the 1920s, Germany's Albert Helwing invented the "flying tourbillon" (flying tourbillon ), an unsupported tourbillon, to keep the tourbillon as flat as possible.

Tachometer
Watch speed is the watch outer ring engraved with 500/400/350, followed by the reduction of the number of chronograph, these representatives of the physical speed, in kilometers / hour, the bezel called the tachometer.
Rolex Daytona
How to use : Take the vehicle driving on the expressway as an example, because the expressway usually has a distance indicator rod on the highway; the stopwatch is started when passing the starting point, the stopwatch needle starts counting at 12 o'clock, the time is stopped when moving 1km, The number at this moment is the average speed of the previous kilometer.
For example, at 12 o'clock there are 60, because a minute walk 1 km, then the speed is 60 km / h.
Tudor Monte Carlo Ref.7032 / 0 Chronograph
Bezel on the number corresponding to the location is how to figure out it? it's actually really easy. To know that 500 this number should be engraved in that position? Then you need to do a simple division; that is, how much time it takes to travel 1 km at 500 km / h, in seconds.
1 hour = 3600 seconds, then 500 kilometers need 3600 seconds to complete, according to the principle of equality, the time required for 1 km is 3600/500 = 7.2 seconds, so 500 must be engraved in the dial at 7.2 seconds. Similarly, 400 should be engraved in 3600/400 = 9 seconds, while 100 is engraved in 36 seconds.
At speeds of less than 60 km / h, the tachometer can not be used directly, unless a lower speed scale value is added.

Power reserve display
On the dial you will usually have a power reserve display window representation. Mechanical watch will show how long you can run before winding, quartz watch shows the battery level.

The German letters "AUF" and "AB" represent full strings and depletion status respectively
Earliest power reserve appeared on the Nautical Clock centuries ago when ships sailing on the sea relied on time-honored sailing beacons to measure longitude and ensure sailing safety. Due to the timepiece is powered by mechanical devices, if there is not timely winding, it will happen when walking is not allowed to stop or even go. As a result, watchmakers began looking for a device that can visually display energy.
How it works : By measuring mechanical clockwork spare power (winding volume of the degree), on the table of the energy for intuitive instructions. This indicating device, however, usually also has a fan-shaped window on the surface of the timepiece and indicates the margin with a pointer.

There are two main criteria for evaluating the pros and cons of a power reserve: one is long power, that is, the longer the motive power reserve time is, the better the time it takes to keep the watch running. The second is the more uniform the energy reduction rate the better.
If a watch decay faster and faster of its energy, it will not go away. Therefore, the longer the energy reserve watch, the more uniform attenuation, the higher the requirements of tabulation technology, the table more difficult to do.

Steal phenomenon
General automatic winding mechanical watch is the use of the human arm to complete the movement of the chain, but if the watch is parked for too long, or because people wear a watch daily activity is very small, resulting in insufficient chain on the table, motivation is not enough to form a go.
Omega coaxial device with coaxial escapement 2500 movement is one of the important inventions of the 20th century mechanical watch industry, but also troubled by stolen
In particular, some of the table, the self-winding design itself has shortcomings, the problem is even more prominent. Run into such problems, can only be appropriate to lengthen the wear time, or by manual chain to solve.
If there is no problem with the power, it may be the problem of the watch's movement itself. Some people wear a watch for a long time do not wash the oil care, the movement has a lot of dust, grease, rust, resulting in small debris, and sometimes gear will be small debris stuck and stole. Then there is the table has been dropped, subject to large vibration, which caused the stop-go walk, then you have to watch the clock master repair and maintenance.
Omega subsequent 2500D and the new 8500 movement enabled three coaxial escapement wheels, and thus solved the problem of theft on the coaxial movement
Stealing at night is not necessarily lack of motivation, the watch on the day or date window is the beginning of the night beating, if there is stopped here may be damaged jump parts or stuck.
Read this period, presumably we have a more profound understanding of the watch, we next want to know which watch terminology? Please feel free to leave a message
