OMEGA Constellation

The Omega Constellation 131.23.41.21.06.001 pairs a 41 mm steel case with Sedna gold. It stands 13.45 mm thick, with a lug-to-lug span of 44 mm. A domed sapphire crystal with anti-reflective coating on both sides covers the grey dial. The self-winding calibre 8900 drives the watch, a Master Chronometer movement certified by METAS and resistant to magnetic fields up to 15,000 gauss, fitted with a free sprung-balance and silicon balance spring. Alongside the date, it offers a time zone function, and the transparent caseback shows off the rhodium-plated rotor and Geneva-waved bridges. A grey leather strap with rubber and alligator surface finishes the piece, closed with a stainless steel foldover clasp. Omega rates the case to 50 metres.
