1950s OMEGA Cal.320 Rare 37mm Oversize Chronograph with Pulsation Dial (Unpolished Case)

This is a very rare 37mm oversized chronograph with a silver two-tone dial, manufactured in 1959-60 and equipped with the famous Omega Cal.320.

It is equipped with Cal.320, a two-resistor version of Cal.321, which is also used in Speedmaster. This watch is equipped with the two-resistor version of Cal.321 Cal.320, which is also equipped on the Speedmaster. In this era, the screw back version is also available in 34mm size, and the 37mm size is very rare except for sports models, whether water resistant or not. The dial is a three-dimensional two-tone specification, and the wedge indexes and the alpha hand common to Speedmasters of the same age are a precious gem that fascinates the aspect of the age and the taste with the texture by aging.
