You see, if you don't wear it, the watch will need servicing because it is an automatic anyway. Part of the servicing a a total disassembly of the watch and re-polishing of the case and bracelet, This returns the watch to like new.
So you might as well wear it because even though it will pick up scuffs and scratches, it can be fixed during the service intervals. Before you ask, Rolex doesn't give you any discount on servicing if your watch doesn't need re-polishing and they will still disassemble the watch because the gasket at the back needs to be changed to maintain the water depth rating and it needs to be re-tested. Also the lubricants in the automatic assembly needs to be removed and re-applied and the watch needs to be retested for accuracy.
If you're that paranoid about the watch, do what I do and buy more, then you will stop worrying. I wear my watches to work and I work outside on utility poles. When it is service time, I get a fully refinished watch.
Here is an example of a watch that is so old they don't make parts for it anymore and was most likely pretty beat up that came back from a service and restoration.
