About the 7750

An automatic chronograph designed at Valjoux and now produced by ETA. Its three-register layout, with 30-minute and 12-hour counters and small seconds, and its day-date at 3 o’clock are familiar across a wide range of mechanical chronographs. The cam-and-lever mechanism gives the pushers a firm, deliberate action, and watchmakers who service it know its construction well.

30-minute and 12-hour counters, small seconds
