GRANDEUR Tilt — Amethyst, three-quarter view

01 24° Angled Tourbillon

GRANDEURTilt

The watch that hides nothing.

The Grandeur 25° Angled Tourbillon is built around an in-house skeleton calibre, revealed through a fully transparent Grandeur UltraClear 8 glass case. Its architecture is defined by a 25-degree inclined tourbillon, a purple sapphire tourbillon bridge, a sapphire dial, and a visible 50-hour power-reserve display.

Designed to bring depth, light, and mechanical motion to the foreground, this timepiece turns the movement itself into the main design language.

04 The Signature

It doesn’t sit flat — it Tilts into the spotlight

Grandeur’s signature is the 24° angled tourbillon, set at an inclined position to create depth, motion and a stronger presence on the dial. It becomes the beating mechanical centrepiece of the watch.
