Description
This vintage Omega Seamaster De Ville was produced in 1966. The watch features a stainless steel case with a 34.5mm diameter. The dial has a white sunburst effect with light patina speckles visible, The condition overall remains very pleasing and characteristic for its age.
Inside is a caliber 562 automatic movement, which was serviced in March 2026 and now runs and functions excellently. The crown is an original Omega crown, although not original to this specific reference, yet it operates perfectly and could always be replaced with the correct version in the future if desired.
We have paired the watch with a top grain leather strap in brown with a crocodile motif and a light glossy finish, which suits the watch very well. Overall, this piece presents beautifully and would make for a refined vintage dress watch.
