Using your Tag Heuer Aquaracer is a breeze. Just set the time by pulling out the screw-down crown and turning it. The turning bezel can be used to measure elapsed time. When you're out swimming or in water, remember it's water-resistant up to 200m, but don't operate the crown underwater. For maintenance, keep it away from magnetic fields and extreme temperatures. Wipe it with a soft cloth regularly to keep it looking great. And every few years, it's a good idea to take it to a professional for a check-up.
