OMEGA Constellation

The Omega Constellation 131.58.29.20.55.003 is a women's model in yellow gold measuring 29 mm across. The case has a thickness of 12 mm and a lug-to-lug span of 31.2 mm, a compact fit suited to a smaller wrist. A self-winding movement, calibre 8701, drives the watch and carries Master Chronometer certification from METAS, with resistance to magnetic fields up to 15,000 gauss. The domed sapphire crystal has antireflective treatment on both sides. This Constellation is set with diamonds and includes a date display, with a transparent caseback showing the movement's Sedna gold rotor and balance bridge. Green alligator leather forms the strap, closed with a pin buckle in matching yellow gold. Water resistance is rated to 50 metres.
