Product description

Casio G-Shock GA-B2100BEG-1AER

The Casio G-Shock GA-B2100BEG-1AER is a solar-powered analogue-digital watch built around an octagonal resin case with a multi-layered dark grey dial and integrated negative-display digital window.

The 45 mm matte black resin case sits lugless, with a textured rubber strap growing directly from the case structure in parallel ridged bands. Stepped baton hour markers line a raised chapter ring above the main dial surface, while two central hands carry luminous fill and a small sub-dial with a green pointer sits at nine o'clock. Mineral glass covers the dial. The digital window, positioned between three and six o'clock, shows green-tinted text on a negative display, and four labelled push buttons protrude from the case sides to operate the chronograph, day, date, 24-hour display, stopwatch, and digital time display functions.

G-Shock's Octagonal Heritage

Casio was founded in April 1946 in Mitaka, Tokyo, originally as Kashio Seisakujo, before becoming Casio Computer Co., Ltd. and building the G-SHOCK line into a central part of its watch catalogue. The GA-2100 series draws its octagonal bezel directly from the DW-5000 and inherits the minimalist character of the AW-500, presenting both shapes as a modern continuation in the analogue-digital lineup. The GA-B2100BEG-1AER is identified by Casio and reputable retailers alike as a limited-edition entry within that line.

Solar Power at 20 ATM

The Casio G-Shock GA-B2100BEG-1AER runs on solar quartz, removing the need for periodic battery changes as long as the watch receives sufficient light. At 20 ATM, it is rated for diving. The 45 mm resin case with a measured thickness of 12 mm and a total weight of 52 g keeps the overall build light on the wrist.

Movement

Watch type
  • (Read more) Wristwatch Analogue
    An analog wristwatch is a traditional timepiece with hands that display hours, minutes, and seconds on a dial.
Movement
  • (Read more) Quartz
    The clockwork is quartz, which means that it is battery powered. A quartz movement is easy to maintain and ensures that the watch is always accurate.
Energy
  • (Read more) Solar
    Solar watches are quartz watches that harvest their energy from light and store it in a rechargeable battery, eliminating the need for battery changes. Manufacturers often equip their watches with small solar panels on the surface of the movement, constructed from two layers of silicon, a material that efficiently absorbs and utilises sunlight and its energy. Once the battery is charged, the watch functions in the same way as any other quartz watch.

Features

Water Resistance
  • (Read more) 20 ATM / 200 meter
    The watch is water resistant to 200 meters of water pressure (20 ATM) under static conditions without movement or temperature fluctuations. This means the watch is resistant to swimming and light diving. However, the watch is not classified as a diver’s watch, and we do not recommend diving deeper than 15 meters while wearing the watch.
Glass
  • (Read more) Mineral Glass
    The watch is equipped with mineral glass, a hardened and heat-treated glass material that provides flexibility, making it more resistant to shattering upon impact. Scratch and wear resistance are measured on the Mohs hardness scale, which ranges from 1 to 10. Mineral Glass ranks at 5-6 on this scale.
Clasp Type
Buckle
Lumen
  • (Read more) LED Light
    The watch is equipped with an LED light that can illuminate the dial or display, so you can always check the time whether it is by day or night.
Functions
  • (Read more) 24-Hour Display
    The 24-hour function on an analog watch displays the time in a 24-hour format instead of the classic 12-hour format. This function makes it easy to quickly determine whether it is day or night, as the hands move around the dial once a day.
  • (Read more) Date
    The watch is equipped with a date display that advances every second time the hour hand passes 12 o'clock. The date display counts up to 31 days and must be manually adjusted in months with fewer than 31 days.
  • (Read more) Day
    The day display on an analog watch shows the day of the week, often positioned in a small window on the dial. The day advances automatically every second time the hour hand passes 12 o'clock.
  • (Read more) Digital Time Display
    The digital time display on a watch shows the time in a numerical format, with hours and minutes clearly displayed with numbers.
  • (Read more) Stopwatch
    The watch is equipped with a stopwatch function, allowing you to measure precise timing with start, stop, and reset. This is useful for measuring the duration of activities, event times, or training intervals. The stopwatch function adds a practical tool to the watch that can be used in various situations requiring accurate timing.
