Zenith Automatic Diver ‘Sub Sea’ Ref. A3637 Gay Frères steel bracelet

Zenith Automatic Diver ‘Sub Sea’ Ref. A3637

A striking classic tool watch from the late 1960s with real character. This Zenith Diver from the legendary ‘Sub Sea’ family captivates with its solid stainless steel cushion-shaped case and deep black dial with the iconic bright orange minute hand – a functional detail originally designed for better readability underwater. The dial displays a charming, even patina on the tritium indices and bears the classic Zenith logo with the four-pointed star.

A special highlight for collectors is the original ‘ladder’ steel bracelet from the renowned manufacturer Gay Frères (GF), stamped with ‘2 68’ (second quarter of 1968). Not only does it give the watch an unmistakable vintage look, but it also offers extremely high wearing comfort. Inside, a precise Zenith automatic movement (typically calibre 2542PC/2552PC) keeps time. The watch is in honest original condition with clear, authentic signs of wear on the case, bezel and strap, testifying to an eventful life. The glass and black diving bezel show age-related scratches and cracks, which perfectly underline the raw, utilitarian character of this diving watch.
