Using your TAG Heuer Formula 1 Automatic Chronograph is a breeze. The watch's hands will show you the basic hours and minutes, and you can use the chronograph function to time events. Just press the appropriate buttons to start, stop, and reset the chronograph. When it comes to the date, it will automatically update. As for water resistance, while it can handle up to 200 m, it's best not to expose it to extreme water pressure. For maintenance, keep the watch clean by wiping it with a soft, dry cloth regularly. Avoid hitting the watch against hard objects as it might damage the case or internal movement. If you're not going to wear the watch for a while, store it in a dry and cool place. This will help keep your watch in great condition for a long time.
