OMEGA Constellation Observatory

Omega's Constellation Observatory, reference 140.13.39.21.10.001, has a steel case measuring 39.4 mm across. Thickness comes to 12.23 mm with a lug-to-lug span of 47.2 mm. The green dial pairs with a self-winding calibre 8914, fitted with a Co-Axial escapement and a time zone function. A domed, bevelled sapphire crystal with anti-reflective treatment on both sides covers the dial, and a sapphire display back on the reverse shows the movement, finished with an engraved Constellation Observatory motif on the rotor.

It comes on a green alligator leather strap with grained calf underside and a steel pin buckle. Water resistance is a modest 30 metres.
