Omega Seamaster Chronometer Ref. 2577 – Rare 1950s Precision in Gold & Steel

A Seamaster Like No Other – The SeaConstellation

At first glance, it may appear to be a classic early Seamaster. But look closer: this is no ordinary reference. The Omega Seamaster Chronometer Ref. 2577, dating to 1950, is a highly uncommon version equipped with a chronometer-grade movement—something seen in very few Seamasters of the era.

Often referred to among collectors as a “SeaConstellation” for its shared DNA with Omega’s earliest Constellation models, this watch features the revered Calibre 354—an automatic chronometer movement with fine regulation on the balance. A small detail on the dial reveals its elevated status, but the real upgrade lies within: smooth winding, precise timekeeping, and the technical quality only found in Omega’s top-tier movements of the time.

A Golden Case, A Collector’s Dial

This 34mm gold-capped stainless steel case offers a balanced presence, with gentle curves and vintage charm. The dial retains its original layout, and while it shows subtle signs of age, it maintains superb legibility and character—adding to its authenticity and vintage allure.
