Vintage Omega Seamaster 30 Manual Wind 135.007-66 - 35mm - 1966

A vintage Omega Seamaster 30 produced in 1966, presented in impeccable condition. The dial is in a practically perfect state, featuring a vertically brushed finish in a clean white color, complemented by silver accents in the hour markers, Omega logo, and hands.

The stainless steel case measures 35mm in width and remains in excellent condition, perfectly matching the overall quality of the watch. Inside is a caliber 286 manual wind movement, which was entirely serviced in March 2026 and now runs and functions excellently.

The watch is paired with a brown leather strap, the only non-original component. Overall, pieces like this are becoming increasingly uncommon in such well-preserved condition.
