Using your Seiko Prospex Samurai Sea Automatic Diver Watch is easy. Simply wind it manually if the power reserve is low, or let the automatic movement do its job as you move around. When you're going for a swim or a dive, don't worry as it can handle water up to 200m deep. Just make sure the clasp is securely locked. As for maintenance, keep it clean with a soft, dry cloth. Avoid exposing it to extreme temperatures and strong magnetic fields. If you notice any issues with the movement or water resistance, it's best to take it to a professional Seiko watch repairer.
