Heuer CARRERA MIKROGRAPH 1/100th Second Chronograph
Essential technical elements that make this timepiece different:
1 – First chronograph with a central 100th-of-a-second hand turning one revolution per second and 100 jumps per second (3 times faster than on the historical Heuer model). There is no visible tremor during rotation.
2 – Dual control system: one for chronograph functions and one for setting watch time. It’s the first 100th of a second wrist-worn stopwatch.
3 – Extremely easy-to-read chronograph scale on the outside edge of the dial indicating tenths and hundreds of a second.
4 - Chronograph control with column wheel.
5 – Unlike a conventional chronograph, the time base is not dependent on the watch (hence the name “stopwatch”). Chronograph functions can be start or stopped independently of watch functions.
6 - The chronograph’s power reserve is independent of the watch’s (two separated cylinders).
7 - Automatic winding of the watch by means of a circular oscillating weight. Chronograph winding is done manually (once is 90-minute power reserve is depleted). Winding the chronograph also winds the watch — both barrels are wound at the same time.
8 - Chronograph power reserve display by full scale of 120° (the 90-minute-power reserve on a scale from 0 to 100%).
9 – Chronograph second counter at 6 o'clock.
10 – Chronograph minute counter at 3 o'clock.
11 – Small seconds counter at 9 o'clock.
12 – The wide spacing of the counters with respect to the centre makes for excellent readability.
13 – Semi-perpetual date window at 6 o’clock with rapid date correction with crown in middle position.
14 – 42-hour power reserve for the watch and 90-minute power reserve for the chronograph.
15 – The two balance wheels (4Hz clock and 50Hz chronograph) are visible through the open case back.
16 – The stop second enables watch time to be set to the nearest second.
