Vintage Omega Seamaster Cosmic Manual Wind Date 136.022 - 35mm - 1969

This vintage Omega Seamaster Cosmic from 1969 features a vertically brushed silver dial with a dark edge, complete with both seconds and milliseconds tracks. The 35mm stainless steel case retains most of its original sunburst polish and remains in good shape. Inside is a manual-wind caliber 613 movement, serviced in January 2026 and currently running and functioning well. It’s paired with a brown top-grain leather strap with a crocodile motif. Overall, this watch makes a great daily wearer. (There is a tiny scratch between the 10 and 11 hour markers, however only visible from certain angles in bright light.)
