Using your G-Shock GMAS120RB-1A watch is easy. To set the time, you can follow the on - screen prompts. For world time, just select the city you want from the 29 time zones. The stopwatch and countdown timer are handy for timing events; simply press the relevant buttons to start, stop, or reset. The alarms can be set according to your daily schedule, and you can use the snooze feature if you need a little extra sleep. When it comes to the mute function, you can turn off the button operation tone as you like. As for the calendar, it updates automatically until 2099. For the hand shift feature, when you want a clear view of the digital display, the hands will move aside. Maintenance is straightforward. Since it's water - resistant up to 200 meters, you can wear it while swimming, but avoid exposing it to hot water or steam. Keep it away from strong magnetic fields to maintain its performance. When the battery runs out after about 3 years, take it to a professional to replace the CR1220 battery.
