Omega Seamaster De Ville Automatic Ref. 166.020 – A Rosé Gold French-Made Classic from 1964

A timeless expression of post-war refinement and horological ingenuity, the Omega Seamaster De Ville Ref. 166.020 in 18K Rosé Gold is a remarkable representation of 1960s-era craftsmanship. French-case Seamasters such as this one stand out not just for their technical elegance, but for the unique historical footnote they carry—evading Swiss gold export taxes through local casing. The result? A heavier, rosier, and utterly distinctive Omega.

Distinctive French Craftsmanship in Solid Rosé Gold

This 34mm Seamaster De Ville is cased in a solid 18K Rosé gold monobloc (monobloque) French-made case—a hallmark of a fascinating tax workaround from the 1960s. French hallmarks and craftsmanship imbue this piece with a rare richness and heft, enhanced by sharp, untouched lines and its original Omega factory finish.

Its clean and balanced silver sunburst dial, signed by Omega, remains in pristine, untouched condition—free of any restoration—with applied hour markers and classic dauphine hands, all under a domed plexiglass crystal that exudes vintage charm.

Calibre 562 – A Reliable Beating Heart

Inside the case, the revered Omega Calibre 562 automatic movement beats with precision and confidence. Fully serviced by our professional watchmaker and covered by a one-year mechanical warranty, the movement reflects Omega's dedication to reliability and smooth performance in the 1960s.

Paired with a handmade Belgian leather strap, this Seamaster De Ville offers a tactile sense of period-correct luxury. The Omega-signed crown ensures that all components remain authentic and aligned with factory specifications.

Period-Correct Detailing and Pristine Preservation

Flip the case, and the iconic Omega Seahorse emblem graces the caseback—deep, sharp, and impressively preserved. Every aspect of this watch has been maintained with care, offering collectors a rare opportunity to own a French-cased Omega in superb condition.
