Accuracy (Accuracy)
The clock and watch is the most banal, is also the most need to pay attention to the accuracy of mechanical device.Rolex Milguass SS White Swiss Eta 2836 One day (86,400 seconds) deviation (fast or slow) correct time 30 seconds, the machine (in mathematics context, error is 0.035%. In other words, the accuracy is 99.965%. The official authentication of the observatory table (chronometers) error must 0.005%, the 18th century low bosom
Watch, even after fine tuning, a day of error is still in half an hour.
Adjustment (Adjustment)
Alarm Watch (Alarm table)
In default time then automatically attacks emerged and wrist watch sound.
Alarm watch what humans when designing mechanical design of the earliest one of double miscellaneous table 16 century already appeared. Sell today to find a NaoBiao device only ancient pocket watch is not easy. As for the modern wrist watch or theory is quartz, electronic, hand bent or automatic bend it is very common. The following label has alarm watch: MONTBLANC), spindle MONTBLANC (THOMMEN), Raman (REVUE IKEPOD (seaslug alarm), deposition of home and VULCAIN etc.
Analogue, Analog to produce stats indications (pointer type time display)
The term used to reflect: "table face plate to Pointers (branch) rather than digital (digital) to display time".
"Pointer moves around the face plate is traditional display time method. The modern wrist watch also have Windows digital displays month, week and date with points, but keep pointer type, electronic digital (mostly is digital) instructions.
Annealing (toughening change)
Will slow cool again after metal heating, so can reduce metal internal stress (" stress "can be, enhanced toughness, less likely to brittle fracture.
Discuss calandar (lists or in the sun, moon, stars three calendar table)
Every time a XiaoYue (30 days) and intercalary month must date watch. Hands-on set-up For example 100 da feili Ref. The 5035.
Antimagnetic (fight magnetic)
In daily life, appliances and refrigerators, and urban inoculation produce a magnetic field when running, millions of harassment and affected the accuracy. If will balance wheel grab the longitudinal round with clockwork tiffany-twisted all not accept nickel alloy produced by magnetic metal, there is resistance to magnetic effect.
A watch in 4800A/m (every male feet of the magnetic field, 48 amps) if you still can continue to move, one day the maximum error does not exceed 30 seconds, then the watch will be resistance to magnetic table.
There have been no resistance to magnetic table low status. For example, rolex in 1955 the Ref. 6236 stainless steel production, calendar timed magnetic resistance meter.
Aperture (Aperture, Windows)
In table face plate have open hole called window. Ulysse Nardin), for example Athens (the production of Ludwig type calendar wrist, is a year, month, week and date small window.
Arbor (shaft, mandrels)
Machine operation structure axle), is axle (arbor (shaft, mandrels), but to will distinguish, in balance wheel (staff) of the called value, and lever) (axial in it (called the arbor (messenger) heart axis).
Arcaded dial (vaulted face plate)
Looks points not to align into digital scale, but in a circle arc (or vaulted arches). For example JiangShiDan meal in 1998 by the production of automatic jump (saltarello) wrist appearance disk.
Art Deco (adornment Art
Art Deco is Art Decoration, are often mistakenly the abbreviations translated "devices" (device) Art. In fact it is a popular in 20 ~ 30 of the European and American character, stresses line of decorated geometric designs. Modern wrist watch kadeya (Cartier) to have this kind of character design.
Assay (analysis)
Analyze the metal contains gold or silver identity.
Astronomical watch (Astronomical calendar table)
Can display the sun, the moon and the stars, including the project location when time equation, average into the sun, sunrise, sunset time, the zodiac chart, the star test time and star chart.
Ancient pocket watch will have similar design, the most famous is the most modern miscellaneous namely is double the 100 da feili Calibre 89. As for wrist watch have local astronomical calendar utility of including 100 da feili 5002, when the project in Athens, like the trilogy (Galileo doppler with Copernicus), other caleb treasure ji, Abby and Franck Muller and have time equation. The works of the wrist watch
Atmos Clock (air Clock)
Neither need bent, also do not need batteries, but using atmospheric temperature difference as energy provide clock running energy. This is air clock. The most famous product home products. Other, accumulate home still for millennium made a special design, can record the millennium operation.
