Watches should be wound regularly a set number of turns to prevent over winding and a watch that is not being used should also be wound occasionally to keep the movement running free. The hands should only be set by turning them clockwise, never try to turn them backwards.
Only an expert should repair, clean or oil the movement of a watch which is very delicate and can be damaged easily. Do not attempt to clean a watch dial as this too is easily damaged. Do not polish the case too often as this will wear off any decoration or metal coating. Never wet the watch or case. If the case is silver, lightly polish it with a long term silver cloth, not silver polish, powder or water as they may get into the movement. Polish a gold case very lightly with a very soft cloth as gold is soft and the decoration can wear off. Silver gilt in particular should only be polished when absolutely necessary and then only lightly with a silver cloth. If possible,wear cotton gloves when handling watches to prevent finger marks, which can cause tarnishing, being left on the case.
