Using your G-Shock GA-100 watch is a breeze. Just press the buttons on the side to set the time, date, and other functions. You can also use it to check the stopwatch or alarm. When it comes to water resistance, it can handle up to 200 meters, so you can wear it while swimming or snorkeling. But don't take it for deep - sea diving. For maintenance, keep it away from strong magnets as it's magnetic resistant but strong magnets can still affect it. Wipe it with a soft, dry cloth regularly to keep it clean. If the battery runs out after about 2 years, take it to a professional to replace the CR21220 battery. And remember, this watch is built to withstand shocks, but try not to drop it intentionally.
