Using this Seiko watch is easy. Just put it on your wrist and fasten the clasp. If the watch stops, you can wind it manually to start it up. When it comes to maintenance, keep it away from water as it's not suitable for long - term submersion. Wipe it with a soft cloth regularly to keep it clean. Avoid hitting it against hard objects to prevent damage to the case and dial. In case you have any issues, it's best to take it to an authorized Seiko service center.
