Special characteristic

ETA 7750 Movement

After the takeover by ETA, the Valjoux 7750 was re-named the calibre ETA 7750. This is quite possibly the most successful automatic chronograph movement of all time. The calibre stands out due to its high degree of accuracy and robustness. It has 25 stones, a ball bearing mounted rotor and a uni-directional winding mechanism. The 7750 has a 1/8-second counter, a 30-minute counter, a 12-hour counter, 28,800 half oscillations per minute and has a power reserve of ca. 44 hours. The loss of accuracy is 1-6 seconds per day. Movement revisions are recommended every 3 to 8 years

Special characteristic

Golden screw-down pushers

Screw-down pushers confer an additional mechanical aspect to watches. In order to operate the stopwatch function, one has to first unscrew the collar and, then, close it again after stopping it.
