Using this Seiko Presage watch is easy. Just put it on your wrist and use the push - button on the deployment clasp. To set the time, you can use the manual winding feature. Remember, it has a power reserve of about 72 hours, so if you don't wear it for a few days, it might stop. You can wind it manually to get it going again. When it comes to maintenance, keep it away from strong magnetic fields as they can affect the movement. Also, avoid exposing it to extreme temperatures. Clean it gently with a soft cloth regularly to keep it looking its best. It's water - resistant up to 10 bar, but don't wear it for deep - sea diving or long - term submersion in water.
