Having just purchased a 3rd Automatic Watch, i was in need of a winder to keep them all running and up to date. After recieving this winder i was really surprised at how well it worked. It was big enough to handle all my dive watches,  the largest  having a 25mm wide bracelet and a 17 mm deep case, and the others 22mm wide and 14mm deep with the extra wide adapter. With the choices of clockwise and counter clockwise rotation and numerous timimg choices,this should be able to handle most watches. Mounting the watches was easy and being spring loaded kept the watches secure while running. Although this winder is mainly comprised of plastic, the motors are unnoticeably quiet. PEOPLE..This is a great buy you won't regret.
