Within this perfect compact cube, we discover the most sophisticated technology. Equipped with a sixth-generation ultra-silent motor, it emits virtually no magnetic charge. Autonomous, for a minimum of three years, its power stems from two standard 1.5-volt alkaline batteries or a mains power supply. On leaving the workshops, the Masterbox is programmed to perform a bi-directional rotation of 1,600 revolutions per day. Thanks to its USB or Bluetooth system, the programming of the number of revolutions and the direction of rotation of the watch winder can be completely personalized. As soon as the watch winder is paused or in standby mode, the watch is repositioned vertically in the 12 o’clock position.
