Using this Diesel watch is a breeze. Just look at the analogue display to tell the time easily, and check the date display for the current date. When you're out and about, don't worry about a little splash as it has 50m water resistance. But avoid wearing it for long - term underwater activities like deep - sea diving. To keep your watch in top shape, wipe it with a soft, dry cloth regularly. Store it in a cool, dry place when you're not using it. If the watch stops working, it might be time to change the battery. You can take it to a professional watch repair shop for battery replacement.
