Vintage Omega Seamaster Lady Manual Wind 535.012 - 23mm - 1969

A Vintage Omega Seamaster produced in 1969. This watch has the exact design and aesthetics of the Omega Seamaster Cosmic, yet this model does not display Cosmic on the dial. It features a 23mm gold plated case, making it perfectly suitable for a lady’s wrist. The dial is golden colored with dark blue edging, creating a beautiful contrast and elegant vintage appearance. The overall condition of the dial and case is exceptional and shows very little wear. Inside runs the Omega caliber 630 manual wind movement, which was recently overhauled in March 2026 and now runs according to factory specifications. The watch is paired with a brown leather strap and presents itself in exceptional overall condition. It comes with its original Omega Box.
