Audemars Piguet x Michael Schumacher Royal Oak Laptimer Watch
It's not just a chronograph. It's not a split-second chronograph. The Audemars Piguet x Michael Schumacher Royal Oak Laptimer Watch is the world's first mechanical chronograph with the ability to compare two consecutive laps at once while preserving flyback functionality. It can measure lap times down to an eighth of a second, thanks to the new, 413-part Caliber 2923 movement that took years of development, uses no fewer than three column wheels, and has a power reserve of 80 hours. It's all encased in a 44mm forged carbon case, with a titanium bezel and back, pushpieces crafted from ceramic and pink gold, and an open black dial with black inner bezel. Limited to 221 pieces.
