Constellation Co-Axial Master Chronometer Small Seconds 34mm

From the retailer listing

The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moon facets, as well as the “claws” on the side of the case. This 34mm model in stainless steel features a bezel with engraved Roman Numerals, a crystal white silvery dial, and a round date window at the 6 o'clock position. The polished hour markers, hands, OMEGA logo and Constellation star are all in 18K white gold, while the Small Seconds subdial and Central Minute Track are circled by rings. Presented on a grey leather strap, the timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8802, visible through the domed scratch-resistant sapphire crystal.
