Omega Constellation 131.28.29.20.99.003 29 mm Steel & Sedna™ Gold Blue Dial Blue Alligator Strap Diamond Watch for Women

Blue aventurine and diamonds meet on the Constellation 131.28.29.20.99.003. Its natural stone dial is encircled by a diamond-paved bezel, and the 29 mm case, stainless steel with 18K Sedna™ gold, keeps the signature claws on its flanks. A shimmering blue alligator leather strap matches the dial, and a date window sits at 6 o'clock.

The hands and hour markers are 18K Sedna™ gold, as are the OMEGA logo and Constellation star. Inside, the self-winding Co-Axial calibre 8700 is certified as a Master Chronometer by METAS, withstands 15,000 gauss and offers a 50-hour power reserve. A stainless steel pin buckle closes the strap, and water resistance is 50 metres.
