Today's offering showcases this rare, classic and pleasing Seamaster De Ville with rare 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.

Ours has a beautiful untouched linen dial.

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.

This pleasing example is original down to the dial, hands, and winding crown. Its very honest, appearing to have had little or no polishing and never having any parts replaced except for the crystal.

Its case is very good condition with only fairly light wear and one wear area on the side of a lug. Its silver linen dial is original and in excellent condition with only light aging.

One of our Master Watchmakers has disassembled the movement down to the last screw and fully serviced it. It is running very strong and true, keeping time on par with a new Omega in our testing recording position.

For the finishing touch, we have equipped it with a vintage styled Connoisseur of Time leather strap and aftermarket Omega style buckle making it ready for immediate enjoyment.

We also stock lizard and a variety of other straps in various prints, skins, and colors. Please ask us if you're interested.

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