Invented by the Büren Watch company in the 1950s, it reduces the size of the rotor which requires a certain amount of space to function correctly and often increases the size of the watch. (See "Rotor" or "Oscillating weight".) TAG Heuer used this principle in the Calibre 12 in 1969.
Industry:Timepieces
A watch with hands showing the hours, minutes and seconds, but which also features a mechanism for measuring continuous or interrupted units of time, from a fraction of a second to twelve hours. This supplementary mechanism is operated manually by push-pieces that set in motion, stop and return the hands to zero. The chronograph hand or seconds-hand indicates seconds, fifths of seconds or tenths of seconds. Counter hands total minutes and hours. Thanks to digital display and quartz movements seconds can even be divided into hundredths and thousandths.

A watch with a movement that has demonstrated outstanding accuracy by passing the tests of the COSC (the official Swiss Chronometer Control Office). Each movement is individually checked in five positions: crown left, crown right, crown up and dial up. Its accuracy must remain between -4 and +6 seconds over 24 hours, and the deviation may not vary by more than 5 seconds during the 15-day test period. Testing is done at 8°C, 23°C and 38°C. Only watches with movements that have passed this testing process are officially certified as chronometers. In general, the word "Chronometer" appears on the dial.
