Intermittent Rotation:Instead of constant rotation, watch winders use a cycle of rotation and rest. This is crucial because it avoids over-winding the watch and allows the mainspring to function as it would when worn on the wrist.
TPD Settings:The duration of the rotation and rest periods are determined by the "turns per day" (TPD) setting on the winder, which is specific to the watch model.
Delayed Start:Some high-end winders even feature a delayed start function. This allows the mainspring to unwind slightly before the winder begins its rotation cycle, further mimicking natural wear.
Overwinding Prevention:The stopping and starting mechanism is vital to prevent overwinding, which can put stress on the watch's mainspring and potentially shorten its lifespan.
