Vintage 1950 Omega Seamaster Calendar Serviced Bumper Watch Ref 2827-1 An elegant and increasingly collectible early Seamaster, this 1950 Omega Seamaster Calendar Ref. 2827-1 represents the golden era of post-war Swiss watchmaking. Powered by Omega’s charming bumper automatic movement, this piece offers the distinctive feel of the early self-winding system, where the rotor “bumps” gently against its springs rather than rotating freely. It is a wonderful reminder of mid century mechanical innovation and craftsmanship. This watch has just undergone a service by us to ensure reliability and longevity, and has been fitted with a new quality leather strap, ready for comfortable everyday wear. The dial is particularly attractive, displaying a beautiful, even patina that only decades can create. Applied hour markers and the applied Omega logo give the dial depth and refinement, while the date window positioned at 6 o’clock adds symmetry and practicality, a desirable feature in early Seamaster Calendar models. The Ref. 2827-1 is a classic 1950s dress-sport crossover: refined enough for formal wear, yet robust enough for daily use, exactly as the Seamaster name intended. A timeless and mechanically engaging vintage Omega, serviced and ready for its next custodian.
