An Oris watch is a high-quality Swiss Made object. But even so, you should avoid direct contact with solvents, detergents, perfumes and cosmetic products as these may damage the gaskets and affect your watch’s water resistance. Generally, we do not recommend exposing leather straps to water or any other liquid as this can cause damage to the fine leather we use. If you’re likely to wear your watch while swimming, you might want to choose an Oris with a metal bracelet or a rubber strap, or invest in one as a temporary replacement. The Oris Strap Shop has lots of options.
