Using your Seiko Prospex watch is easy. Just wind it up if it stops or when you first get it, and it will keep running for about 72 hours. To set the time, pull out the crown and turn it gently. When you're out in the water, it can handle depths up to 100 meters, but don't press the buttons underwater. For maintenance, clean the watch regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures or strong magnetic fields. If you notice any problems, take it to a professional watch repairer.
