Seated on ballbearing rollers is a rotating plastic lined stainless steel hollow cylinder into which the watch is mounted on elastomeric self-conforming cushions. There is no metal-to-metal contact as the drive rollers are equipped with nitrile rubber drive rings at both ends.
Controls are provided on the circuit board for 4 different turns per day (TPD) settings (650, 800, 950 and 1300).
Lighted LED digital displays are provided for extremely accurate quartz-based 12-hour time (AM and PM) and the turns per day indicator is the other 4 digit LED display.
Each cycle, or turn of the winder, ends up with the watch positioned in a new incremental position. The succeeding cycles each repeat the 390º rotation resulting in 30º steps. After 12 cycles the watch has circumscribed a full 360º.
