Brand: GruenTypology: Vintage diver watch
Year: 1960
Design often bears the imprint of fashion, which generally evolves, for utilitarian objects, according to the introduction of functional and technical innovations or the appearance of standards.
As far as diving watches are concerned, the arrival of the graduated rotating bezel is, in this sense, an important landmark, if not simply a starting point.
Invented by French combat swimmers Claude Riffaud and Bob Maloubier , it was first implemented in 1952 by Blancpain with its Fifty Fathoms and quickly copied by Rolex, which released the first Ref. 6202 Turn-O-Graph in 1953.
Without knowing the exact time, it is assumed that Gruen will unveil its Autowind Waterproof model around the same time. Its designers then naturally aligned themselves with the standard set by Blancain and adapted it in the same way as Breitling, with a wide concave bezel.
