Product Description
The G-SHOCK GMAS2100RB-1A is a sleek and compact timepiece, a midsize take on the iconic GMA-S2100 with an octagon bezel. Its black and deep red color combination, along with a shiny metallic finish, adds a touch of elegance. This watch comes with a 46.2×42.9×11.2mm case, made of carbon and resin for the case and bezel, and a resin band. It features a Carbon Core Guard Structure for shock resistance and mineral glass for durability. With 200 meters of water resistance, it's great for various water activities. The white double LED light ensures clear visibility in the dark. It offers world time across 31 time zones (48 cities + coordinated universal time, daylight saving on/off), a stopwatch, timer, 5 daily alarms, and a full auto-calendar up to 2099. The mute feature allows you to turn off button operation tones, and it supports both 12/24-hour formats. The hand shift feature moves the hands aside for an unobstructed digital display view. It keeps regular time with analog 2 hands (hour, minute with 20-second hand movement) and 1 dial (day), as well as digital hour, minute, second, pm, month, date, and day. It has an accuracy of ±15 seconds per month and an approximate battery life of 3 years on two SR726W batteries.
Using your G-Shock GMAS2100RB-1A watch is easy. To set the time, look for the buttons on the side of the watch. You can switch between different functions like the stopwatch, timer, and alarms using these buttons too. When traveling, use the world time feature to quickly adjust to different time zones. The watch is water-resistant up to 200 meters, so you can wear it while swimming or snorkeling, but avoid high-pressure water activities like scuba diving. To keep it in good condition, clean it regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures or strong chemicals. If the watch stops working, it might be time to replace the batteries, which should last about 3 years.
