Using this Seiko watch is easy. To use the chronograph, just press the buttons on the side of the watch to start, stop, and reset the timer. The date calendar will show the current date automatically. When it comes to maintenance, keep it away from strong magnetic fields as they can affect the watch's accuracy. Clean the watch regularly with a soft, dry cloth to keep it looking great. Since it's water - resistant to 100 meters, you can wear it while swimming, but avoid wearing it in hot tubs or saunas as the extreme temperature changes can damage the watch. If you have any problems with the watch, it's best to take it to an authorized Seiko service center.
