Design & Craftsmanship
The Art of Open-Heart Transparency
The True Square Open Heart transforms mechanical watchmaking into visual art. The open dial architecture provides an unobstructed view into the beating heart of the calibre, allowing wearers to observe the rapid oscillation of the balance wheel and the fine perlage decorations beneath rose gold or rhodium-toned accents.
Patented Plasma Ceramic Science
Subjected to activated gases at extreme temperatures, white high-tech ceramic transforms into a glowing metallic grey material without the addition of any metal. The result is a scratch-resistant, non-magnetic surface that adapts instantly to skin temperature for unmatched all-day comfort.
Swiss Calibre R734 with Nivachron™
Inside beats the Swiss-made automatic Calibre R734. Equipped with a titanium-based Nivachron™ balance spring, the movement resists magnetic fields from smartphones, laptops, and travel electronics, ensuring reliable precision across an 80-hour autonomous power reserve.
