Omega Constellation 131.20.39.20.52.001 39 mm Steel & Sedna™ Gold Silver Dial Diamond Watch for Men

Diamond indexes distinguish this steel and 18K Sedna™ gold Constellation, reference 131.20.39.20.52.001. Each stone sits in a Sedna™ gold holder on the opaline white silvery dial, matched by Sedna™ gold hands, logo and star, with the date at 6 o'clock. The 39 mm case shows the collection's claws and a bezel engraved with Roman numerals.

The self-winding calibre 8800 is a Co-Axial Master Chronometer tested by METAS, with a silicon balance spring, 15,000-gauss magnetic resistance and a 55-hour power reserve, finished with Geneva waves in arabesque on rhodium-plated surfaces. A two-tone mono-rang bracelet with butterfly clasp and comfort setting completes the watch, water resistant to 50 metres.
