The C1 tourbillon gravity is presented in a 48.5 mm white gold case, standing 18.50 mm tall. A rubber-coated white gold protective ring, fixed laterally by 7 self-blocking screws is enhanced by seven decorative elements straddling the bezel. These bastions protect a spectacular 3.30 mm thick sapphire crystal, which literally emerges from the case. The skeletized dial displays a dark DLC-coated perforated grid, various subdials and time measurement indications, superimposed to create a sense of perfectly mastered space. This timepiece holds a mechanical, hand-wound movement, Concord Caliber C100, with an 84-hour power reserve, seconds on the side of the tourbillon carriage, trust index (indication of the balance amplitude) and flyback chronograph (hours-minutes). The tourbillon cage is fitted outside the movement and case, but connected to the rest of the mechanism by a perpendicular pinion.
This spectacular time keeper is presented on a black rubber strap with a white gold folding clasp and is water-resistant to a pressure of 3 ATM.
