Using your TAG Heuer Aquaracer is a breeze. Just look at the dial to tell the time and check the date. To set the time and date, unscrew the crown gently and turn it as needed. Then screw it back down tightly to keep the water resistance. When you're wearing it, avoid hitting it against hard objects as it can damage the case or the diamonds. For maintenance, clean the watch regularly with a soft, dry cloth. If you wear it in water often, rinse it with fresh water after to remove any salt or chemicals. Every few years, it's a good idea to take it to a professional for a thorough check-up and servicing to keep it running smoothly.
