28,800 vibrations per hour (8 vibrations per second), a long power reserve of approximately 80 hours, and the brand's first in-house developed movement certified by the Swiss Official Chronometer Testing Institute (COSC). The main plate, barrel, gear train bridge, etc. were all designed in-house, and by increasing the length of the mainspring, it was possible to drive for a long time. In addition, in order to stabilize the accuracy, a large rotor that matches the 14-inch movement is installed to improve the winding efficiency of the mainspring.
