Using this TAG Heuer Aquaracer is simple. Just wear it on your wrist like any other watch. The folding clasp push - buttons make it easy to put on and take off. As it's an automatic watch, it winds itself when you move your arm, but if you don't wear it for a while, you can manually wind it to keep it running. When it comes to maintenance, keep it away from extreme temperatures and magnetic fields. Clean the steel case and band regularly with a soft, dry cloth. If you take it swimming or diving, rinse it with fresh water afterward to remove any salt or chlorine. Also, have it serviced by a professional every few years to ensure its long - term performance.
