This is a highly rare 1930s Omega watch featuring the renowned Caliber 33.3CHRO, housed in a stainless steel, 37mm Calatrava chronograph case with a unique two-tone sector dial. It is equipped with the valuable early version of the Caliber 33.3 with a single pusher. The Calatrava case, with its wide and flat bezel, exudes a sense of weightiness despite its non-waterproof design.
The outer sector dial layout features a large snail tachymeter scale, encapsulating the charm of the 1930s. The ivory-colored patina adds to the individual beauty of the watch, making it a truly outstanding piece.
