The COSC-certified Concord C1 Chronograph
The COSC-certified Concord C1 Chronograph marks the launch of a truly new construction born of an unusually sophisticated concept drawn from advanced technological research and innovation. This powerful timepiece asserts its exceptional personality through an ambitious watch case 44 mm in diameter and 16.7 mm from front to back – a study in sturdiness at its best.
  
Assembled to absorb and dampen blows and jarring, 53 components make up a case water-resistant to a pressure of 20 ATM. A rubber-coated protective metal ring featuring eight decorative tabs that extend over the bezel, is fitted over the middle case and secured by seven self-blocking side screws. The system protects an impressive, 3.3. mm-thick anti-reflective sapphire crystal that seems to emerge from the case. The setting crown is composed of steel, rubber and composite materials, enduringly interlocked for greater compactness and resistance. A raised C1 logo on the rubber end-piece adds a final touch to the design.
The case’s open case back reveals the watch’s self-winding movement, which runs at 28,800 vibrations per hour and offers 48 hours of power reserve. Finished in black rhodium for dramatic contrast, the oscillating weight achieves an assertive elegance with its cut-out of the C1 logo silhouetted through a ribbed Côtes de Genève decorative pattern executed in the finest horological tradition.
Made of carbon fiber and finely milled metal, the dial is a complex multilevel creation designed to accentuate visual depth and perspective. Enhanced with black trim and luminescent material, the hour and minute hands sweep over a dial rimmed with hollowed-out markers filled with a luminescent compound. As the hands’ asymmetrical cut-outs create a play of forces on the center axis, fitting and poising them requires exceptionally deft hands. At 9 o’clock, the ingeniously engineered running seconds subdial features a rotating disk barely 0.1 mm thick. At 3 o’clock, the date seems to fade in and out of the dial aperture. The 30-minute and 12-hour counters are positioned at 12 and at 6 o’clock respectively. Finally, the first quarter of the minute circle is color-matched to the sweep seconds hand’s vibrant Concord blue color.
