Ref. 92.103 | Calibre Valjoux 7736 handwinding | Diameter 40mm

This Flygraf is yet another iconic model from the 70's Yema chronographs. Introduced in 1970 and re-released in 1978 and a couple of times after that. This watch aimed at pilots and other aviation fans has a cockpit like drawing on the dial and an outer uni-directional calculator bezel to measure speed in relation to time. The inner caramel colored dial ring is just stunning. On the back you'll find the well-known Yema logo.

The handwinding Valjoux 7736 movement  is part of the 7730-series Valjoux (dual-register with small-seconds sub dial at 09.00, a jumping 30-minute counter at 03.00, and a central seconds counter) has produced in  late 60's until the late 70's. A high-quality chronograph movement used by several known watch brands in those days. 

The 7730 was the renamed Venus 188, after a slight modification this became the 7733 with variants with date (7734), 12 hour counter @6 o'clock (7736) and 10-minute regatta countdown (7737).
