Omega Constellation 131.23.29.20.99.001 29 mm Steel & Sedna™ Gold Green Dial Green Alligator Strap Watch for Women

Natural green aventurine stone forms the dial of this 29 mm Constellation, reference 131.23.29.20.99.001, paired with a shimmering green alligator leather strap in the same shade. The case combines stainless steel and 18K Sedna™ gold, with claws on the sides, Roman numerals engraved around the bezel and the date shown at 6 o'clock.

The OMEGA logo, Constellation star, hands and hour markers are all crafted in 18K Sedna™ gold. The self-winding calibre 8700 inside is a Co-Axial Master Chronometer approved by METAS, resistant to 15,000 gauss, with a silicon balance spring and 50 hours of power reserve. A stainless steel pin buckle fastens the strap, and the watch resists water to 50 metres.
