FL104 — Bi-Colour — 37.5 mm Favre-Leuba traces its history back to 1737, placing it among the oldest names in Swiss watchmaking. The 1960s and 1970s were an important chapter for the brand, when Favre-Leuba produced some of its most recognisable vintage sports watches. This Waterdeep belongs to that golden era. This is a vintage Favre-Leuba Waterdeep automatic diver, dating to around the late 1960s or early 1970s and fitted with the in-house Favre-Leuba FL104 automatic calibre. The watch’s defining feature is its attractive bi-colour design.
