OMEGA Constellation

The Omega Constellation 131.28.29.20.58.001 measures 29 mm across in a case of steel and Moonshine gold. The case stands 12 mm thick with a lug-to-lug span of 31.2 mm. A domed sapphire crystal with antireflective treatment on both sides covers the yellow dial, which is set with diamonds. Inside is the self-winding calibre 8700, a Co-Axial Master Chronometer movement certified by METAS and resistant to magnetic fields up to 15,000 gauss, with a power reserve of 50 hours. The date sits on the dial, and the caseback is transparent so the movement can be viewed. A brown alligator leather strap closes with a steel pin buckle. The case holds a 50 metre water resistance rating.
