Using your Seiko Presage Sharp - Edged Series Limited Edition watch is easy. Just wind the crown gently to set the time and date. If your watch has stopped, wind it about 20 - 30 times to get it started. Remember to keep it away from strong magnetic fields as they can affect the movement. When it comes to water resistance, it can handle splashes and short swims but avoid hot tubs and deep - sea diving. To keep your watch looking great, wipe it with a soft, dry cloth regularly. And once a year or two, take it to a professional watchmaker for a full service to ensure it keeps ticking accurately.
