You prevent winding stem repair by not ever winding your watch using the stem! Granted watches are designed to be wound with the stem, however, Rolex and other Watch makers assume you will be wearing the watch and not need to use the stem to wind it very much if at all. The problem is they never counted on collectors! They also never counted on the practical need to not wear your valuable watch sometimes. Therefore modern men tend to over use the winding stem. On top of this is a curious psychological twist about the psyche of a man. We like to "do things well!". Ever notice a man stapling something? Putting up a poster? Nailing something? Just one more staple, just one more pin, just one more nail for good measure! Just one more twist of the winding stem, POP! $600 stem repair bill, plus the loss of your watch for weeks and weeks! Why risk it? Get a winder and never need to fix it!
Repeated manual winding of a watch can damage the watch stem. Repairing the stem of an expensive watch can cost hundreds of dollars. In addition, if there is no local jeweler available to perform the work, you may have to ship your watch and risk further damage.
The best way to prevent Stem Repair is to store your watch on a Watch Winder when you aren't using it. Best of all, your watch is ready to wear next time you want it. You won't have to set the time.
A winder will save you money in the long-run by protecting your watch.
