The G-Shock GA2100RL-1A is a modern and stylish timepiece. It flaunts a minimalist design with a black case, dial, and strap, giving it an understated yet contemporary look. The octagonal bezel not only adds to its trendy appearance but also ensures shock resistance, maintaining G-SHOCK's famous durability. It comes with double LED lighting - one for the face and another for the digital display. Both have Super Illuminator and selectable illumination durations (1.5 or 3 seconds), making it easy to read in low - light conditions. The hand shift feature moves the analog hands aside for an unobstructed view of the digital display. This watch offers world time across 31 time zones, covering 48 cities and coordinated universal time, with daylight saving on/off option. It also has a 1/100 - second stopwatch, countdown timer, 5 daily alarms, hourly time signal, and a full auto - calendar up to 2099. Time is shown through analog hands (hour and minute, with the minute hand moving every 20 seconds) and a digital readout for hour, minute, second, pm, month, and date. With an accuracy of ±15 seconds per month and a 3 - year battery life on two SR726W batteries, it's a reliable choice.
Using your G-Shock GA2100RL-1A is a breeze. To set the time, find the relevant buttons on the side of the watch. For world time, you can easily switch between 31 different time zones by following the simple instructions in the manual. The stopwatch and countdown timer are great for sports or other timed activities. Just press the appropriate buttons to start, stop, or reset them. When it comes to the alarms, you can set up to 5 daily alarms to remind you of important events. To turn on the LED lights, press the designated button. You can choose between 1.5 or 3 - second illumination durations. As for the hand shift feature, when you want to see the digital display clearly, the hands will move out of the way automatically. For maintenance, keep your watch clean by wiping it with a soft cloth. Avoid exposing it to extreme temperatures or strong impacts. Also, if the battery runs out after about 3 years, take it to a professional to replace the two SR726W batteries.
