Using this Seiko watch is easy. Just wear it on your wrist and fasten the clasp securely. The watch has an automatic movement, but you can also wind it manually if needed. To read the time, look at the luminous hands and markers, which are visible even in low - light conditions. The day/date calendar is a handy feature that shows you the day and date. When using the rotating bezel, turn it gently in the correct direction. For maintenance, keep the watch clean by wiping it with a soft cloth regularly. Avoid exposing it to extreme temperatures or strong magnetic fields. If you plan to swim or do water - related activities, it's water - resistant up to 100 meters, but make sure the caseback is tightly screwed. If you notice any issues with the watch, it's best to take it to a professional watch repair service.
