Using this TAG Heuer watch is easy. Just adjust the time by pulling out the screw-down crown gently and turning it. When you're done, push it back in and screw it down tightly to keep the water resistance. This watch is great for daily wear and can handle water up to 300 meters deep, but avoid hitting it against hard objects. To keep it looking its best, clean the bracelet with a soft cloth regularly. If you notice any problems or need a battery replacement, it's best to take it to an authorized TAG Heuer service center.
