A Seamester De Ville, all steel and white gold on the linen dial makes quite a vintage gem! It has a 34,5 mm case diameter and a slim 9,7 mm height. The manual caliber 610 movement numbered 21534222 is fully overhauled and guaranteed for 12 months. The Omega serial number 21534222 dates the production to 1964. This fits nicely with the decorative engraving on the back with the initials B. H. and the date 3rd July 1965. The perfect linen dial with the slim baton hour markers and hands makes this a very desirable vintage Seamaster.
