OMEGA Constellation Observatory

The Omega Constellation Observatory 140.53.39.21.99.002 measures 39.4 mm in rose gold. The case stands 12.23 mm thick with a lug-to-lug of 47.2 mm, and the pink dial sits beneath a domed, bevelled sapphire crystal with anti-reflective treatment on both sides. Inside is the self-winding calibre 8915, a Master Chronometer movement with a Co-Axial escapement and a silicon balance spring, certified to resist magnetic fields up to 15,000 gauss. It also has a time zone function, and the rotor and balance bridge carry a Sedna gold finish with an applied Constellation Observatory medallion. Power reserve runs to 60 hours, and a display back reveals the movement. The watch is fitted on a burgundy alligator leather strap with a rose gold pin buckle. Water resistance is rated to 30 metres.
