Omega Constellation Co-Axial Master Chronometer — Ref. 131.12.41.21.06.001Video footage available upon request. Open to offers. Bracelet sizing service available.About This ReferenceThe modern Constellation carries forward one of the most recognisable case designs in watchmaking — the signature half-moon facets at the lugs and the four "claws" gripping the sapphire crystal are hallmarks that have defined the collection since 1982. The 131.12.41.21.06.001 presents the 41mm stainless steel case on a black rubber strap, pairing the Constellation's dressy identity with everyday wearability. The silk-embossed rhodium-grey dial catches light with a textured finish, while the blackened hands, facetted indexes, Omega logo, and Constellation star create a coherent, understated colour palette. A bezel engraved with Roman numerals frames the dial, and behind it all the calibre 8900 — METAS-certified and resistant to magnetic fields above 15,000 gauss — delivers 60 hours of power reserve with Co-Axial precision visible through the transparent caseback.SpecificationsModel: Omega Constellation Co-Axial Master Chronometer Reference: 131.12.41.21.06.001 Caliber: 8900 (Master Chronometer, METAS certified, 39 jewels, 25,200 vph, Si14 silicon balance spring) Case: Stainless steel, 41mm × 13.45mm, with signature half-moon facets and "claws" Bezel: Fixed stainless steel with engraved Roman numerals Crown: Pull-push Crystal: Domed scratch-resistant sapphire Caseback: Transparent sapphire Dial: Silk-embossed rhodium-grey, blackened hands and facetted indexes with luminous fill, blackened Omega logo and Constellation star, date at 6 o'clock Strap: Black rubber Clasp: Brushed stainless steel folding clasp Movement: Automatic Power Reserve: 60 hours Water Resistance: 50m / 165ft Functions: Hours, minutes, seconds, dateCondition ReportOverall condition is excellent.
