1930s Longines Cal.12.68z Staybrite 32mm Calatrava rare Two-tone sector dial

A rare two-tone sector dial from the late 1930s Longines, equipped with the famous Cal. 12.68z movement, in a 32mm Staybrite case with a Calatrava design. The flat bezel beautifully complements the Calatrava case, which, although not waterproof, has the characteristic solid construction of Longines. The two-tone sector dial showcases the style of the era, making this a valuable piece. The renowned Cal. 12.68z movement, which comes in various versions such as small seconds, center seconds, and stop seconds, is housed within. One of the charms of this model is its unique construction, including matching serial numbers engraved on both the case and movement, distinguishing it from later models.
