Using your TAG Heuer 41mm Automatic Carrera watch is simple. Just buckle the fold - over clasp with pusher release on your wrist. The watch will keep accurate time thanks to its automatic movement, which winds as you move your arm. For the best performance, try to keep it on your wrist as much as possible during the day. When it comes to maintenance, keep the watch away from extreme temperatures and magnetic fields. You can clean the stainless - steel case and bracelet with a soft, dry cloth. If you notice any issues with the timekeeping or the clasp, it's best to take it to a professional TAG Heuer service center.
