I was hesitant to order such a low price winder, after seeing much more expensive items around...This winder is cool looking, it fits two large case size watches (42- 46mm with thick rubber bands). It is quiet, and in 4 weeks of use, so far, my two automatics are still keeping time correctly, with the programmable winding set for 30 minutes every 3 hours. I can see buying another as soon as I find another 2 automatics I want.
