A 45mm leviathan, it incorporates the in-house ML 106-7 calibre (developed from the ML 106 base chronograph movement) bearing the patented lever which guarantees precision by locking the zeroing function when the chronograph hands are in operation. The 60-minute chronograph counter, along with the small seconds counter is shaped like skeletal discs, resembling tyre rims.

Further into the labyrinthine structure, the hand-decorated bridges plated with black gold come into view. And against this chic mechanical web is the snailed architecture and black screws of the bottom plate, golden gears, and black balance wheel that blends inconspicuously into its surroundings.

As an indication of refinement, Maurice Lacroix combines a variety of finishes on the steel case: Polished sunray, circular- and vertical-brushed. The dials are coated with anti-reflective coating on both sides for a clearer view of the movement, and treated with a slate-grey metal coat to enhance the effect of the double counters. A black hand stitched crocodile strap rounds off the watch. Limited to 250 pieces.
