Manufactured in the mid-1940s, this is a rare early-type bumper automatic model equipped with the Omega Cal.28.10RAPC movement. It features a scarce gray gilt luminous dial. In 1943, Omega introduced its first automatic movement, the Cal.28.10RASCPC, which is integrated into this timepiece. This watch is a valuable half-rotor bumper automatic model from before the era of full-rotor automatic models. It showcases a unique structure, including a snap-type case back with a metal O-ring for waterproofing, and a Gothic-style luminous Arabic numeral gray gilt dial that reflects the essence of the time. The vintage charm is enhanced by the appealing patina and significant character of aging, making it an exceptional piece with a wonderful vintage taste.
