Using this Shinola watch is a breeze. Just wind up the automatic movement by gently moving your wrist around. To set the time, pull out the screw - down crown and turn it to the correct time, then push it back in and screw it down tightly. Since it's water - resistant up to 100 meters, you can wear it while swimming or snorkeling, but avoid high - pressure water activities like scuba diving. For maintenance, clean the watch regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures or harsh chemicals. If you notice any issues with the movement or water resistance, it's best to take it to a professional watch repair service.
