I suspect there is benefit in running a watch every so often - same as with an old car or a woman it pays to turn it on occasionally and get the lubricants flowing more freely. I am just doubtful whether a winder really saves any effort to be worth the money or pretence. Unless you have dozens of high end watches in which case Butler is for sure the more appropriate option, otherwise you need to keep detailed spreadsheets liek

on which watch was wound and when, for how long etc... and who could be fucked?
