The floating flange stands out because of its bronze colour reminiscent of the magnesium alloy wheel rims on a racing car. The second interpretation has a case in pink gold, a noble material that makes a striking contrast with the forged carbon and seiko SPA843P1 Ladie's watches black ceramic bezel, as well as with the left side of the case middle and its forged carbon element designed like a ventilation duct. It also contrasts with the carbon pushpiece guards, which further exemplify the meticulous detailing on this model.
A slender black aluminum strip engraved with the seconds numerals is fixed to the lower bridge of the tourbillon, and thus fully interdependent with the carriage which spins on its axis once a minute. The luminescent seconds appear through an open window on the side of the tourbillon carriage, and since the latter is seiko SPA843P1 watches vertical, are perfectly visible on the face of the watch. This completely innovative mechanism is entirely in line with the already surprising small seconds display on the C1 Chronograph. Mastering time and space: power reserve, trust index, flyback chronographThe third challenge lay in optimized technical sophistication and an irreverent design.
The majestic C1 Tourbillon Gravity makes an authoritative statement in a case measuring 48. 5 mm in diameter and 18. 5 mm thick. Its construction, now a Concord brand signature, features excellent shock absorbing properties and exceptional sturdiness. A rubber-coated white gold protective ring placed on the case middle and secured on the seikoSPA843P1 side by seven self-locking screws, is enhanced by seven decorative elements straddling the bezel. These "ramparts" protect a monumental sapphire crystal a full 3. 3 mm thick, glareproofed on both sides, which literally seems to rise out of the case.
