Zenith launched a limited edition boutique watch for the Marcus boutique in London-Christophe Colomb Skeleton skeleton watch. Like the original Christopher Columbus watch released in 2010, the design is inspired by the legendary precision marine timer. The most breakthrough design of the watch is to set the adjuster and escapement system in the frame of the automatic adjustment gyro module to ensure that the speed regulation mechanism can reduce the rate change in the flat position. Zenith said that the tourbillon fixed rate change will occur on average 4 to 6 positions, while the tilt and gyro tourbillon will change in more positions, but this is still inaccurate data. However, Zenith’s new patented system allows the escapement to be kept at a constant level, further reducing the rate of change. Different from the original, its dial and movement are hollow, and the wearer can clearly see the mysterious bottom plate, bridge and gears inside. The sapphire disk and blue steel hands at 12 o’clock indicate the hour and minute functions, the small seconds at 9 o’clock, and the power reserve indicator at 3 o’clock. With black alligator leather strap, waterproof to 30.
