It features applied faceted steel hour markers with distinct black inserts, complemented by an applied Omega logo, Constellation script, and the signature applied star at the six o'clock position. The date aperture at three o'clock is framed in stepped steel. A careful visual inspection reveals honest, age-consistent characteristics, including light spotting and minor surface debris scattered across the dial, particularly visible under macro magnification. The outer minute track is crisp and fully intact. The original steel baton hands feature matching black inserts and show moderate surface oxidation and aging consistent with the era. Small luminescent plots reside at the outer edge of the hour markers, displaying a creamy aged tone with some natural degradation present. Case and Crystal The 35 mm stainless steel C-shape case is a masterclass in late-century design, characterized by its integrated lug profile and robust tonneau silhouette. The case exhibits excellent structural integrity, maintaining the crucial visual contrast between the vertically brushed upper surfaces and the smoothly polished case flanks. Honest signs of wear, including superficial scratches and handling marks, are present but do not detract from the strong lines of the watch. The fluted crown provides excellent grip for setting the time. Turning the watch over reveals a screw-down caseback adorned with the legendary Geneva Observatory medallion, featuring eight crisp stars representing Omega's precision records. The medallion remains sharply defined, indicating careful wear over the decades. The inner caseback correctly bears the Omega hallmarks and the reference number ST 168 0056. A clear crystal protects the dial and sits cleanly above the polished bezel.

Dimensions Case Size: 35 mm (excluding the crown) Remarks The C-shape Constellation remains one of the most celebrated and wearable vintage Omega designs available to collectors today. Its combination of an integrated case aesthetic, a high-frequency chronometer movement, and an incredibly legible dial makes it a versatile companion for both formal and casual settings. This example, with its crisp observatory medallion and superb mechanical health, represents a tremendous opportunity to acquire a legendary reference. History Introduced in 1952, the Constellation was born out of Omega's desire to create a series-production watch that met the most rigorous chronometer standards in the world. The famous observatory medallion on the caseback pays homage to the brand's sweeping victories at the Kew-Teddington and Geneva observatory chronometry trials in the mid-20th century. By the late 1960s, the Constellation line evolved to include the C-shape case, bringing a modern, architectural feel to the collection while maintaining the uncompromising mechanical excellence that defined the Constellation nameplate.
