"Memosail" Regatta Sport chronograph watch for men with a 10-minute countdown timer. Functional chronograph watch with reset function. Valjoux 7737 from 1972. The name "Memosail" was registered in 1971 (and in the United States in 1973). This original watch had a round, chrome-plated brass "UFO" case, which was later replaced by an almost square case. Both were later replaced by stainless steel cases during their production run. In the mid-1970s, this watch’s barrel-shaped case was introduced, and the word “vip” was added to the dial. The plexiglass has signs of wear on both sides of the dial. Leather rally strap, almost new
