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 3,000 movements were split across nine models, making each model in effect a "limited edition." The 560 was a movement made only for the U.S. market to cut down on import tariffs.

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.

It is a one owner watch and has just finished an expertly done sympathetic restoration, which took just under a full year. It is fully Omega and presents in beautiful condition. Our photos couldn't do it justice.

Its case presents in excellent condition. Its dial has been well-restored by one of the leading dial experts in North America. It retains its original Spiedel bracelet, which very closely resembles an Omega Beads of Rice bracelet. The clasp has one ding. Otherwise it is in excellent condition. Please inquire if you would like a leather band. We are an authorized dealer for the largest band manufacturer in the United States.

One of our watchmakers has disassembled the movement down to the last screw and cleaned and oiled it and installed a new correct style Omega crown. It winds smoothly and is keeping very accurate time. It has been carefully detailed 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 attesting to its performance.

Note: Published examples of similar watches can be found in Marco Richon's work Omega: A Journey Through Time, 2007, pg. 403.
