Omega Seamaster DeVille Ref.136.020 Cal.610 Manual-Wind 1964

A refined and minimalist Omega Seamaster DeVille from 1964, this Ref.136.020 features a slim 34.5mm monocoque case and a reliable Caliber 610 manual movement. Released during Omega’s transition to the more elegant “De Ville” line, it’s a perfect mix of vintage charm and everyday wearability.

The original sunburst silver dial remains pristine, paired with stick hands, applied indices, and a crisp date window magnified at 3 o’clock. Not to mention the perfectly aligned crosshair on the dial, a strong symbol of originality. Fully serviced in April 2025, the watch comes on a black Ostrich leg leather strap with its original Omega stainless steel buckle.
