1966 Omega Seamaster 166.003

The 1966 Omega Seamaster ref. 166.003 is a superb example of vintage Omega craftsmanship, combining timeless design with the warm character that only a well-preserved gold-plated Seamaster can offer.

Its elegant gold-plated case is paired with a beautiful pearl dial, creating a refined and sophisticated aesthetic, while applied gold hour markers add depth, warmth, and excellent legibility. The result is a watch that feels effortlessly stylish more than half a century after it left the Omega workshops.

Powering this classic Seamaster is the highly regarded automatic Calibre 565 movement, celebrated for its reliability, precision, and smooth performance. Turn the watch over and you'll find the iconic Seahorse caseback, a signature feature of the Seamaster collection and a tribute to Omega's rich heritage.

Finished on a premium black leather strap with a signed Omega buckle, this vintage Seamaster is equally at home as an everyday companion or a standout piece within a collection. A timeless watch that perfectly balances elegance, history, and enduring Swiss craftsmanship.
