Using your Fossil Vale BQ3659 Quartz Chronograph Watch is a breeze. To set the time and date, simply pull out the crown and turn it to adjust. The chronograph function allows you to time events. Press the top button to start and stop the timer, and the bottom button to reset it. When it comes to water resistance, it can handle splashes and short swims up to 50 meters, but avoid long - term submersion or high - pressure water activities like diving. For maintenance, keep your watch clean by wiping it with a soft, dry cloth regularly. If the watch gets wet, dry it thoroughly. When not in use, store it in a cool, dry place away from direct sunlight and strong magnetic fields. Replace the battery as needed to keep it running smoothly.
