The engineer series constant-power tourbillon watch was first launched in 2013, and now also welcomes the 18K red gold case. The patented constant power mechanism is integrated inside the tourbillon, which decouples the escapement from the direct power transmission of the gear train, ensuring stable balance amplitude and travel time. The design of the dual barrel can not only provide the larger torque required by the constant-power tourbillon, but also the moon phase display device to provide power support.
