Lapis Lazuli

The Louis Moinet crown guard


Lapis Lazuli

The dial of this Treasures of the World unique piece features intensely blue lapis lazuli, carefully selected and expertly worked by Daniel Haas, a world specialist in the realm of semi-precious stone-dial craftsmanship.

The natural beauty of the lapis lazuli is perfectly complemented by the mechanical majesty of a tourbillon escapement.

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

Lapis lazuli is a rare, semi-precious stone that has been cherished since antiquity for its intense blue colour, derived from the presence of the S3- radical anion in the crystals it contains. Lapis jewellery has been found at Predynastic Egyptian and ancient Sumerian sites.

Lapis is Latin for “stone” and lazuli is Medieval Latin meaning “heaven” or “sky” in reference to the sky’s blue colour. Lapis lazuli therefore means the “stone of heaven” or “sky stone”.

The dial is completed by the highly-polished, hand-bevelled three-armed bridge supporting the tourbillon which extends vertically to the open mainspring.

Turning over this Treasures of the World timepiece reveals the intricate ‘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 – as well as the Côtes du Jura engraved movement plate.
