Omega Seamaster 300

About this reference

The Omega Seamaster 300 reference 165.024 was produced between approximately 1964 and 1970. Collectors prioritize this reference for its asymmetrical twisted-lug case design, which measures 42mm and features integrated crown guards. It typically houses the caliber 550 or 552 automatic movement, known for its reliability and copper-colored finish. Key evaluation points include the presence of the original "big triangle" dial at the 12 o'clock position and the condition of the fragile acrylic bezel insert. This reference was notably issued to the British Royal Navy, and examples with verifiable military engravings command significant premiums. On the current secondary market, standard civilian models generally trade between $8,000 and $15,000 depending on originality and patina. Rare military-issued "MilSpec" versions have reached prices exceeding $30,000 at specialized auctions. Authenticity is critical, as many examples contain service replacement parts or aftermarket components.
