re: OT Watch Enthusiasts: Do you use a watch winder?

No, I don't bother with automatic winders very much. I rotate through most of my mechanical watches enough that they get wound periodically and the ones I don't wear often I'll hand wind a little. The oil will oxidize regardless so keeping the movement running vs letting it idle will have virtually no impact on when they should be serviced. If you have the work done by a skilled watchmaker they'll use a variety of greases that will often far outlast the factory lubricants. Rolex specs a rather mid-grade lubricant and a good watchmaker will substitute a better, specifically blended lube.
