Croton Chronomaster Aviator Sea Diver ref. 106 Yachting Valjoux Cal. 7733 circa 1970s This timepiece comes from an interesting era of Chronographs and vintage tool watches. Not only were these pieces fitted with fine movements and keenly designed dials, but there is also design language and production overlap— specifically ranging from Nivada Grenchen, Croton, and Bulova. Covering both Air and Sea, this one is a fun daily driver and strap monster. While service history is unknown, the manual winding is smooth, the chrono function is starting, stopping and resetting properly and the timekeeping is approximately +27 seconds a day face up and -1 face down (your experience may vary).
