Australian Opal

Diamond-set bezel and lugs


Australian Opal

The dial of this Treasures of the World unique piece features eye-catching Australian opal, carefully selected and expertly worked by Daniel Haas, a world specialist in the realm of semi-precious stone craftsmanship.

The natural beauty of the crystal opal is perfectly complemented by the mechanical majesty of a tourbillon escapement.

Central silvered hour and minute hands as well as silvered hour markers are thrown into sharp relief by the resplendent gemstone that surrounds the tourbillon at 6 o’clock and open-worked mainspring at 12 o’clock.

Opal is one of the most spectacular precious stones in gemology and a layer of lacquer has been applied to this one to bring out its spectacular, sparkling blue and turquoise reflections.

The dial is perfectly complemented by the bezel and lugs set with 56 scintillating Top Wesselton VVS baguette cut diamonds that total 3.46 carats, with the case crafted in 18k white gold.

Turning over this Treasures of the World reveals the ‘octopus spring’ of the winding and setting mechanism through the display-back, effectively three springs in one – pull-out piece spring, lever spring and click spring – while the impressive Côtes du Jura engraved movement plate is equally on show.
