I own six diplomat winders including this little gem. It spins a 270 gram watch with no difficulty. I have had mine for four months and keep it near my bed. The movement is soundless and runs like a champ.  I have had good success with the diplomat brand of winders as oppossed to the problems some have had with the more expensive brands. A great piece of furniture this is not. It just does the job of keeping your watches wound. Watches with a max band width of 26mm and 50mm case width should fit.
