Omega Seamaster 300

About this reference

The Omega Seamaster 300 reference CK2913 was produced between 1957 and approximately 1961 as part of the professional "Master" trilogy. Collectors prioritize this reference for its historical status as Omega’s first dedicated divers' watch, featuring a 39mm straight-lug case, a "Broad Arrow" hour hand, and the caliber 501 automatic movement. Early iterations are distinguished by their countdown bezels and thin "thin-arrow" seconds hands. Due to the fragile nature of the original acrylic bezel inserts, examples with intact, original components are rare. On the secondary market, prices typically range from $15,000 to over $50,000 depending on the specific sub-reference and condition. A notable variant is the "Military" version issued to the British Royal Navy, which features fixed lug bars and specific caseback engravings; these rare military-spec examples have achieved auction results exceeding $100,000.
