Manual winding or self winding/automatic watches need special handling. The manufacturers have their own way of taking care of their products, but this article applies to every mechanical watch.
Watches are made to wear on your wrists and as such will be subjected to some wear and tear. However, protect your watch from any impact even if it is shock-proof. Contact with detergents, perfumes, solvents, etc should also be avoided as they could corrode the watch. And most importantly, if you are not using your watch, store it in a dry place on a soft surface, away from any extreme temperatures.
