Wearing (and not wearing)
Strenuous activity – Watches were made to be worn. But not always. If you’re getting ready to exercise, work in the garden, or go rock climbing, it would be best to leave your watch at home. A good rule of thumb: when in doubt, don’t wear it. If you think an activity might damage your watch, you’re probably right.
Too much sun and exposure to heat – Sunlight can fade the color of a leather belt or turn a black dial to dark brown over time. Too much heat can also reduce the life of your battery.
Soap, perfumes, and creams – Keep lotions and perfumes away from your watch and watch band, especially if the band is made of leather.
Bumps and Splashes – While most luxury watches are safe from a sudden rainfall or a splash from the pool, it’s best to keep water away from them. Moisture can weaken leather bands and they may crack and break. Be sure to keep the crystal away from objects that may scratch or break it.
