Using your Seiko 5 Sport SRPK18 is easy. Just wear it on your wrist and let your daily movements power the automatic mechanism. If you want to give it an extra boost, you can use the manual winding feature. To read the time easily, look at the luminous hands and markers on the black dial. You can also check the date and day on the calendar. For timing an event, use the uni - directional rotating bezel. When it comes to maintenance, keep it clean with a soft, dry cloth. Avoid exposing it to extreme temperatures or chemicals. Since it's water - resistant up to 100M, you can wear it while swimming, but don't use it for scuba diving. If you have any issues, it's best to take it to a professional watch repair service.
