Lumillion

The world’s first lume tourbillon is the result of over 24 months of dedicated development. Integrating luminescent material into the tourbillon required precise adjustments to restore balance, and several other components of the movement were substantially customized in the process.

The Lumillion elegantly displays the hours with quarter-hour markers illuminated by Swiss BGW9 luminescence, positioned along the side of the dial. Time is read at the red luminescent marker.

The uniquely contoured case gently slopes to emphasize the time-reading area. Crafted from ultra-light Grade 5 titanium, it features a distinctive Damascus aluminum dial encircling the central lume tourbillon. A sapphire crystal with anti-reflective coating crowns a sleek 42mm case, just 5.6mm thick. Paired with a 5.7mm sapphire glass, the total profile is a precisely measured 11.3mm.

At its core is a modified and regulated Hangzhou 37Z0E movement, meticulously enhanced by the Grandeur team to deliver a daily accuracy of +3 to +6 seconds at 28,800 bph. The movement offers a 42-hour power reserve and features 29 jewels for outstanding precision.

Interchangeable FKM rubber straps attach beneath the case for a seamless, integrated appearance. A Grade 5 titanium clasp provides both durability and comfort for daily wear, along with 5ATM water resistance. The Lumillion unites precision, innovation, and design in one remarkable form.
