Swiss-made masterpieces with dials designed by nature: The Omega Constellation Aventurine.

These extraordinary 29 mm models have dials made from natural Aventurine stone, which means no two dials are ever alike. There are twelve new editions, in stainless steel and 18K Sedna™ Gold or full Sedna™ Gold for purists – all with natural Aventurine stone dials in either green, red or blue.

Fans can choose bezels paved with diamonds or engraved with Roman numerals. Replacing the famous mono-rang bracelet are leather straps in colours to match the dial. The driving force behind the natural dials is OMEGA’s Co-Axial Master Chronometer Calibre 8700 – or 8701 for the all-gold models.

The trio featured have diamond-set bezels, skeletonised hour and minute hands and dial matching leather straps in shimmering blue, red with glittered scale lines or green. Providing the power is OMEGA’s Co-Axial Master Chronometer calibre 8701, visible through the domed scratch-resistant sapphire crystal.
