This double watch winder has 3 stationary pillows and runs on 2 "D" batteries or supplied AC adapter. The turning mechanism does about 5 turns per minute and has 3 different programs available. Program (A) - Turn clockwise only for 33 minutes and then rest for 15 minutes. This cycle is repeated 12 times per day achieving 1,860 turns. Program (B) Alternating- Alternating clockwise and counterclockwise rotation every 10 seconds for 3 minutes and then every 5 minutes for the next 30 minutes. The same cycle is repeated 14 times per day achieving 2,170 turns per day. Program (C) - Turn counterclockwise only for 33 minutes and then rest for 15 minutes. This cycle is repeated 12 times per day achieving 1,860 turns. Note: There is a rest period every hour (which is very different than most other brands of watch winders that rotate continuously all day). The watch will use up some stored energy during this rest period and reduce any chance of over winding the watch. It measures 6 3/4" x 9" x 9 1/4" and is made of a piano styled glossy wood finish.
