Digital-Age Watchwinding Technology. One of the most notable features of the TOURBILLON watchwinder is its ability to make any mechanical watch, in effect, a Tourbillon watch. Each cycle, or turn of the winder, rotates the watch 390° — resulting in 30° steps. After 12 cycles the watch has circumscribed a full 360°. This action cancels out the effect of gravity on a watch's balance wheel mechanism.
