The Seamaster De Ville, showcasing both refinement and high function, was the most important Omega line from a sales perspective from the latter part of the 1960's into the 1970's. It has a monocoque - or one piece - case which insured water resistance and slim, elegant profile. The case when new achieved high water resistance ratings by not having a separate case back.

Today's offering showcases this rare, classic and pleasing all original Seamaster De Ville with caliber 560 movement of which only 3,000 examples were made.

These movements were split across nine models, making each in effect a "limited edition." The 560 was a movement made only for the U.S. market to cut down on import tariffs.

It is all original down to the dial, hands, original crown, and original Omega beads of rice bracelet.

Its case is in near mint plus condition. Its untouched silver dial has warmed to a beautiful sepia tone. Its bracelet has received a light polish, and the finish presents as just short of mint, and it has moderate stretch.

'60's and early 70's Seamasters are great long-term buys as parts are readily available for their well-made movements, and they're not hard to service.

One of our watchmakers has disassembled it down to its last screw and cleaned and oiled it making it ready for immediate enjoyment.

Included with the purchase is a one-year international warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.
