Common questions about manuals, registration, and support for this brand.
Ensure that the crown is perfectly screwed down or pushed in after winding the movement or setting the time. Once the crown is fully secured against the case, the watch is guaranteed waterproof according to its depth rating.
If equipped with a self-winding mechanical movement, the watch is wound by wrist movement. If unworn for a long period, you will need to wind it manually by turning the crown clockwise to ensure optimum operation.
For watches, use a microfiber cloth and wash metal, rubber, or waterproof cases with a soft brush and soapy water. Always rinse with fresh water after exposure to salt water. Avoid abrasive chemicals.
Support for YEMA helmets is distinct from the watchmaking division; for helmet inquiries, please refer to the specific retailer or marketplace manual included with your safety gear.
