Object description

Case and Dial Design

The watch is housed in a three-body stainless steel case featuring concave lugs and a transparent case back secured by eight screws. The case measures 40 mm in diameter and 11 mm in thickness, protected by sapphire crystals. Water resistance is rated to 30 meters.

The dial is transparent, providing a view into the movement. It features a white reserve containing Roman numerals for 12, 4, and 8 o'clock, alongside triangular indexes. An outer minute track includes luminous markers at 5-minute intervals. The hours and minutes are indicated by luminous blued steel dauphine hands. A large central aperture allows for viewing the movement mechanics, while a dedicated aperture at the 6 o'clock position houses the one-minute tourbillon regulator with a subsidiary seconds hand.

Movement and Regulation

The timepiece is powered by the Caliber LUC 1.02, a manual-winding movement containing 224 components and 33 jewels. It utilizes four barrels to achieve a 9-day power reserve. The mechanism is a COSC-certified chronometer, featuring a one-minute tourbillon regulator with a lateral lever escapement positioned under a steel wing tourbillon bridge.

The movement is decorated with fausses cotes. The monometallic balance is adjusted to heat, cold, isochronism, and five positions. A self-compensating Breguet balance spring is utilized to ensure chronometric performance.
