Using your Seiko Presage Cocktail Time Automatic Watch is a breeze. You can either let it wind automatically as you move your wrist, or if you're not wearing it for a while, you can manually wind it. To set the time, just pull out the crown and turn it gently. When it comes to maintenance, keep it away from extreme temperatures and magnetic fields. Wipe the watch with a soft cloth regularly to keep it clean. If you're going swimming or in the water, remember it's water - resistant up to 50 meters, but avoid high - pressure water like from a jet. Also, if you're not using it for an extended period, give it a little wind every now and then to keep the mechanism in good shape.
