To use this watch, simply wear it on your wrist. The watch comes with a pre-set time, but you can adjust it according to your local time. For water resistance, it can handle splashes and short - term immersion, but don't wear it while swimming or in the shower. To maintain it, clean the case and band regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures or chemicals. When the battery runs out after about 3 years, take it to a professional watch repairer to replace the battery.
