About this caliber

Self-winding movement with one tourbillon escapement for the time keeping(36,000 VpH - 5 Hz), and another tourbillon escapement for the stopwatch (chronograph) function (360,000 VpH - 50Hz). It appears to be based on the 2012 TAG Heuer Carrera Mikrotourbillons, though that was hand-wound and had the timekeeping tourbillon beating at 4 Hz.
