Using this Daniel Wellington Iconic Link Chronograph watch is a breeze. To tell time, simply glance at the main dial. For the stopwatch function, use the buttons on the side of the watch. Press the top button to start and stop the stopwatch, and the bottom one to reset it. When it comes to maintenance, keep the watch away from extreme temperatures and strong magnetic fields. Clean the stainless - steel case and bracelet regularly with a soft, dry cloth. Although it's water - resistant up to 50 meters, avoid wearing it in hot tubs or while diving as the pressure and chemicals can damage it. If you need to change the battery, it's best to take it to a professional watchmaker to ensure proper installation.
