For this 41.00 mm model, the stainless steel case features a hard metal (tungsten carbide) bezel. The caseback includes a Central Observatory medallion set in scratch-resistant sapphire crystal.

The sun-brushed grey “Pie Pan” dial is reminiscent of the first 1952 Constellation model. Each of its facets includes a month of the year in keeping with the Annual Calendar function. There is a blued Constellation star and OMEGA logo, and blued facetted hands and indexes which have been filled with Super-LumiNova.

This watch has a blue leather strap and is driven by OMEGA’s Co-Axial Master Chronometer Annual Calendar Calibre 8922, featuring revolutionary anti-magnetic technology.
