Using this Seiko watch is easy. Just wind it up if it stops or when you first get it, and it'll keep ticking for about 72 hours. When you're out in the water, it can handle up to 100 meters deep, but don't open the case underwater. For maintenance, keep it away from strong magnetic fields. Clean the watch regularly with a soft, dry cloth to keep the super - hard coating and super - clear crystal looking good. If you notice any issues, take it to a professional watch repairer.
