Combining two admired complications, the minute repeater tourbillon belongs to the very exclusive world of Grandes Complications. Wound-up by two micro-rotors, the watch features a 72h power reserve. Achievement of the highly-skilled Roger Dubuis watchmakers, the watch also houses some useful functions such as an 'all or nothing' indicator to avoid a partial striking of the time, a tone playback indicator to control visually the progression of the repeater and a function indicator to check the crown position (winding or setting) to avoid using the minute repeater while setting the time which could alter the well-being of the caliber. Housed in a SMC carbon case, this watch is a blend of contemporary and expressive Haute Horlogerie.Case C-SMC Carbon case C-SMC Carbon bezel with lacquered markings and sapphire crystal with anti-reflective coating Black DLC titanium open case back with sapphire crystal Black DLC titanium crown overmolded with blue rubber Black DLC titanium pusher Size: 47mm Water Resistance: 3 bar (30 m) Dial Carbon lower flange with transferred texts and minute track, black upper flange with polished and Rhodium plated screw-like hour markers with SLN in the centre Main material: Titanium Strap Black rubber strap with black Rubber Tech inlay.
