The watch requires good daily care
The watch body and band touch the skin directly just as
underwear.
Keep the watch body and band clean in order to avoid stain on the
sleeve edge or rash or itch.
After removing the watch from your wrist, wipe
perspiration or moisture with a soft cloth as soon as possible.
Do not use any chemical agent such as cleaner to clean the watch.
Turn the crown from time to time. (Only several turns in slow movement will be enough.)
This prevents corrosion of the crown and helps to extend the life of the gasket in use.
The same practice should be applied to a screw down crown. (No need to pull out the screw down crown.)
Stainless steel is a highly rust-resistant metal. However, rust will form if contaminants are left on it for a long time.
