OMEGA Rare Stainless Steel 'Jumbo' Chronograph 'Pre-Speedmaster' Wristwatch Cal 33.3 CHRO - c. 1939B The OMEGA Rare Stainless Steel Chronograph Cal 33.3 is a vintage mechanical wristwatch produced by Omega, highly valued by historians and collectors. Its primary distinguishing feature is the inclusion of the manual-winding Calibre 33.3 CHRO movement, which was a robust and reliable chronograph mechanism developed in the 1930s. This specific movement is historically significant because it served as the foundational design for the Omega Calibre 321, which later powered the famous Speedmaster Moonwatch.Stainless SteelSize: 40mm x 43mm;Private London CollectorThis item has been cleared against the Art Loss Register database and comes with a confirmation letter.
