Inspired by Swiss chronographs, the 120 teeth we designed at the bottom of the chronograph ring are engaged in a miniature 12-tooth drive shaft that ultimately drives the miniature encoder to provide input to the motherboard. In addition to the chronograph function, this system can also easily switch the dial and realize functions such as turning pages up and down, which we call Gear-Link. The chronograph on the chronograph ring uses long-lasting luminescent material, and the osicle 1.0GT AI common core platform is built-in, which supports two weeks of long battery life.
