Omega has been mixing jewelley with watches for decades and the new ladies Constellation models feature avenrutine semi-precious dials. Quite trick, not easy to slice stone ultra thin and polish it 100% flush to make a watch dial.
Here’s the word;
Aventurine is the name given to an authentic quartz mineral created by natural forces under the Earth. The shimmering appearance of the gemstone is due to light reflections coming from the multiple shaped inclusions known as mica and hematite, which create a glittering effect that has been loved and revered since ancient times.
You can choose diamond or no gemstone bezels by the way.
Case width is 29mm, full18K gold case models available and some 8700 pieces in all. Prices start at £9190 for the non-diamond models.
