OMEGA’s new 29 mm Constellation 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 Sedna™ Gold – or Sedna™ Gold – all with natural Aventurine stone dials in green, red or blue.

The brand is also offering 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 three models featured in this post have diamond set bezels, skeletonised hour and minute hands and dial-matching leather straps in shimmering blue, red with glittered scale lines or green.

These models are equipped with the OMEGA’s Co-Axial Master Chronometer calibre 8701, which is visible through the scratch-resistant sapphire crystal case-back.
