I have 3 of these. And plan on getting a dual watch version next month. That should keep my 5 "automatic" watches wound, eh?

I do not have large or heavy watches, 3 old Seiko 5's, a Richo 9, all 35 mm cases, and a Yema Sea Spider that's about 39 mm. These single watch winders have been chugging away quietly and so far very reliably.

Was going to get another one or two, but saw the dual watch version and so that will be my next  purchase.
