subject: The professional terms of watch [print this page] Primary three-pin Primary three-pin
Located on the surface together with a small disk used to indicate a second watch, called the "mini three-pin." The second hand, directly installed in the four-wheel axle. It is usually located on the surface 6 of word. Also have individual clocks in 10 words, 9 words, 8 words, 3 words, etc. are, but very rare. As for the second hand and hour hand, minute hand is located in the same center axis, known as the "sweep."
Calendar
In open a small window on the dial to digital instructions month on the 31st, with this feature is the calendar, as known as the date. Date of most direct use of digital, but also the direction pointer, instruction pointer from the date of distribution on the surface of the figure. In addition, there are weeks of instruction because those who called the day. In addition to the date and week, there are those who instructed the name of the month, are called "full calendar" (Full Calendar). Due to a big or small, so in the general calendar, the need for additional calendar adjustment device.
Phase of the moon
Somewatches have instructions on the surface of the small moon window, this feature is called "moon phase" instructions. As we all know, also known as the lunar calendar, it is also expressed as a method of time-varying nature, of great significance in history, especially in China, many people use the lunar calendar, Yici this table is still in the modern production values.
Dynamic instructions
Spare capacity of mechanical watches winding instructions (the extent of tight winding volume) of the feature called dynamic instructions. Usually open in the face of a fan-shaped window, or a pointer directed to the margin.
Alarm watches
Can set the alarm time, alarm clock called the table. After the set time to time there will be a high-speed vibration hammer struck the rear cover and protruding case reminded it is time. There are other music or a voice timekeeping of watches, such as "playing spring table" (Repeater), and "music sheet" (Musical watch).
World Clock
World Clock (Worletimer) after the war to meet the travel demands of the times when the stage and put in the meter. It is able to Greenwich Mean Time (Greenwich Mean Time) as the base, can make the world a time at a glance. Most of the world's Clock engraved with the name of metropolitan and local time, two regions can direct the time, many tricks, such as "Double Time", "Second Time Zone," and so on, but the same basic principles.
Waterproof watch
Glass and the back cover of the joints are coupled with washer and tighten the screw type of table used to, they can prevent the infiltration of liquid and dust. This form generally known as "water table" or "rescue dust table." Early 20's, Rolex has started on the water will use the landmark program. Discharge performance usually in depth over the level of pressure. Daily performance of the table kind of water will generally only 30 meters (3 atm), the expression of 100 meters swimming.
Hours of dancing characters
This is a little window to the surface for 12 hours in each direction of the mechanical part-time, minute hand every 60 minutes through the little window to pop up the next number. Table with this function collectively referred to as "jump the word table" or "hopping table."
Diving
As the name suggests, Scuba diving is the total time used. General water table can not dive, dive table must meet stringent requirements. In short, the water will dive table must have a higher performance, there is time to measure the rotary outer ring diving (there to prevent reverse rotation design), there are easy to read in the dark moments of luminous seabed pointer and scale. Diving is a dangerous activity, not to wear "dive profile," the sports watch diving; these tables only design replica dive watch, can not stand the test of deep-sea pressure.
Antimagnetic watch
Some mechanical watches (rolex watch)are easy to magnetic metal parts, which are often caused by failure reason. IWC development thirties when air table to solve this problem, set the timepiece in the history of great achievements. Shielded by the original method of manufacture of soft iron inner case to reduce the possibility of parts being magnetized, the meat on the table of course, both a double protection. Later, more thorough, simply switch to non-magnetic materials to produce parts.
Watch
Chronograph (Chronograph) is a professional name, which the chrono in Old English and Latin is "time" means, but graph in English means "record tool." General form, continuously directed the passage of time. Time-table is different, it can freely record the length of any period of time. Standard time-table for 30 minutes or 12 hours of time-keeping. The surface of the central seconds hand, usually stopped at the zero position. To show meter running on the road when most of the addition of a constant dynamic small second hand. Time-table at the two, the first object is only one measure of common time-table, the other is the measurement of objects with two sub-two-seconds chronograph.
Chronometer
Chronometer is a precision high-precision timepieces, so it could just called the precision timepieces. Watch a "Chronometer" the word that it after the official Switzerland (COSC: Controle officiel suisse des chronometres) passing inspection, no small matter.
Double chronograph second hand section
This time table has two hours by seconds, the stop state, which is the overlap of two seconds. Click the Clock button, two needles simultaneously started. Click, a needle stop, the other is to continue timing. This is two seconds can be "split" open to use meaning. In addition, click, another branch stop the second hand. This means that people can through mechanical means and accurately "remember" the first seconds to the second branch after the cessation of second hand stops when time elapsed.
Calendar
"Calendar"watch is commonly known as the Chinese people an exaggeration, but the British even more exaggerated, called "permanent calendar" table Perpetual calendar). The so-called "permanent" but that no manual adjustment, if the chain every day, no adjustment can indicate the correct date, their calendar is not on the chain or a thousand years can not always bad. That once a leap year every four years in February only 28 calendar table can only be accurately directed most of the year 2100, IWC launched in 1985, "Da Vinci" can be automatically directed to 2500. Calendar table is a complex mechanical watches, can indicate the date, month, week, or even direct and automatic adjustment of leap year.
