OMEGA Constellation Observatory

Omega's Constellation Observatory ref. 140.93.39.21.99.001 is a rose gold watch measuring 39.4 mm across, with a thickness of 12.32 mm and a lug-to-lug of 47.2 mm. Inside is the self-winding calibre 8915, a Master Chronometer movement with a Co-Axial escapement, certified by METAS and resistant to magnetic fields of 15,000 gauss. Two barrels in series and a free sprung-balance with silicon spring give a power reserve of 60 hours. The rotor carries an applied Constellation Observatory motif in an enamelled 18K white gold medallion. A domed, bevelled sapphire crystal with anti-reflective treatment covers the yellow dial, and the transparent caseback shows the movement. Fitted to a black alligator strap with a pin buckle, the case carries a 30 metre water resistance rating.
