A watch that smells of the sea and regattas: this Memosail regatta timer is a fascinating piece from the 1970s, created to accompany skippers during the hectic 10 minutes before the start of a regatta. Its main function is precisely the 10-minute countdown, with the white/green inner ring and the word "start," legible and immediate, designed to mark the seconds that decide the race. The orange hand stands out in the center, giving a sporty and technical touch to the deep blue dial. The steel cushion case measures approximately 38 mm and houses a Lemania 1345 manual-winding mechanical movement (17 jewels), developed specifically for regatta watches. It is a robust and precise caliber, synonymous with the excellent Swiss school of those years. A rare timepiece with a typically 1970s design, combining vintage charm and sporting functionality. Perfect for collectors of nautical watches and enthusiasts of unusual instruments that are different from the usual chronographs.
