• Avoid activities that may expose your watch movement to shocks. 

• Never use chemicals to clean your YEMA watch. Use a microfiber cloth and wash the metal, 

rubber, fabric bracelets and waterproof cases from time to time with a soft brush and soapy 
water. We recommend that you do not use abrasive or corrosive products  (solvents, detergents, 
perfume, etc.).

back the caseback cover.
