The 41.5 mm Honeygold case is vertically brushed on the sides and polished on the lugs and bezel. The chronograph pushers sit on the right, while a quick-adjust pusher for the perpetual calendar is positioned at 10 o’clock, ensuring easy and intuitive operation.

The grey-tinted transparent sapphire dial allows a direct view of the intricate inner workings of the movement. The large date display occupies the 12 o’clock position, while the month and leap-year indications are integrated within the 3 o’clock chronograph sub-dial. The moon-phase display appears at 6 o’clock, and the 9 o’clock sub-dial combines the small-seconds, day-of-week, and day/night indications. All hands, hour markers, and sub-dials are coated with Lumen luminescent material, glowing a vivid green in the dark.
Inside beats the hand-wound calibre L952.4, composed of 684 parts, oscillating at 18,000 vph with a 50-hour power reserve. The tourbillon mechanism is elegantly concealed on the movement’s reverse side, visible through the sapphire caseback.
Paired with a brown alligator leather strap, the watch is limited to 50 pieces.
