The G-Shock GM2100RW-1A Men's Watch is a real eye - catcher. It features a vivid rainbow color scheme on the dial or watch glass, with the iconic original brick wall pattern from the very first G - SHOCK. The rainbow vapor deposition technique creates an ever - changing brick wall effect, as the colors shift gracefully with the light. This colorful design not only pays tribute to the G - SHOCK heritage but also represents the toughness and perseverance required to overcome challenges. With a case size of 49.3 x 44.4 x 11.8mm and a weight of 72g, it's both substantial and comfortable. It comes with shock resistance, a Carbon Core Guard Structure, a resin and stainless - steel case and bezel, and a bio - based resin band. The mineral glass ensures durability. It offers world time for 31 time zones (48 cities + coordinated universal time), with daylight saving options. It has a timer, a full auto - calendar until 2099, a stopwatch, alarm/hourly time, and a mute feature. The watch has an accuracy of ±15 seconds per month, and the battery, SR726W X 2, lasts approximately 3 years. It supports 12/24 - hour format and has a hand shift feature for an unobstructed digital display view. It's also 200 meters water - resistant. The regular timekeeping includes analogue (2 hands for hour and minute, hand moves every 20 seconds, 1 dial for day) and digital (hour, minute, second, pm, month, date) functions.
Using your G - Shock GM2100RW - 1A watch is a breeze. To set the time, you can use the buttons on the side of the watch. First, find the mode button to switch between different functions like setting the world time, alarm, or timer. For the world time, you can easily select from 31 time zones. When setting the alarm, decide if you want hourly time alerts or specific alarms. The mute feature can be handy in quiet places, just press the relevant button to turn it on or off. As for the hand shift feature, if you want a clear view of the digital display, the hands will move out of the way automatically. Now, for the maintenance. Avoid hitting the watch against hard objects as it, although shock - resistant, can still get damaged. Keep it away from extreme temperatures and chemicals. When it gets dirty, you can use a soft, damp cloth to clean the case, bezel, and band. Since it's 200 meters water - resistant, you can wear it while swimming, but don't press the buttons underwater. And remember, the battery lasts about 3 years, so when it starts to run out, take it to a professional to replace it.
