Steel ‑ Sedna™ Gold on leather strap
131.23.39.20.13.001
The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moons, as well as the “claws” on the side of the case.
This 39 mm stainless steel and 18K Sedna™ gold model features a bezel engraved with Roman numerals, a sun-brushed brown dial and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and indexes are all in 18K Sedna™ gold.
Presented on a brown leather strap, this timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8800, visible through the domed scratch-resistant sapphire crystal.
