Using your TAG Heuer Carrera watch is a breeze. Just wear it on your wrist and adjust the folding clasp with push - buttons to fit comfortably. Since it's an automatic watch, it winds itself as you move your arm. But if you don't wear it for a while, you can give it a gentle shake to get it going. When it comes to maintenance, keep it away from extreme temperatures and magnetic fields. Clean the watch regularly with a soft, dry cloth. If you want to clean the band, use a mild soap and water solution, then dry it thoroughly. Remember to have it serviced by a professional every few years to keep it in top shape.
