Omega Constellation 131.20.39.20.02.002 39 mm Steel & Yellow Gold Silver Dial Watch for Men

Yellow gold sets the tone for reference 131.20.39.20.02.002. This 39 mm Constellation mixes stainless steel with 18K yellow gold in the case and bracelet, while the opaline white silvery dial carries 18K yellow gold hands, indexes, OMEGA logo and Constellation star. A date window sits at 6 o'clock, framed by a bezel engraved with Roman numerals.

Beating inside is calibre 8800, OMEGA's self-winding Co-Axial Master Chronometer, approved by METAS and resistant to 15,000 gauss, with a silicon balance spring and 55 hours of autonomy. The bicolour mono-rang bracelet fastens with a comfort-setting butterfly clasp, and the watch is water resistant to 50 metres.
