1958 Omega Constellation Calendar Automatic Watch 2943 Cal. 504 Chronometer Wristwatch

Watch Overview

This 1958 Omega Constellation Ref. 2943 represents the golden age of Swiss chronometer design — housed in a 35mm stainless steel case with elegant sculpted lugs, smooth bezel, and acrylic crystal. The silver-tone dial features applied gold-tone baton markers, matching hands, and a black minute track, all configured in a clean, symmetrical layout. Signed crown and snap-on caseback marked with the observatory emblem . The watch is fitted with a brown leather two-piece strap, offering a balanced, timeless wrist presence.

At its core is the chronometer-certificated Omega caliber 504 — an automatic movement with 24 jewels, sweep seconds, and a date function. Beating at 19,800vph with a power reserve of approximately 46 hours, it delivers certified precision in classic form. Fully inspected and authenticated by our in-house watchmaker, the watch remains in solid vintage condition with minor age-appropriate wear. A fine example of Omega’s mid-century technical and aesthetic mastery — ready to wear or collect.
