Product description

Casio G-Shock GM-2100YRA-8AER

The Casio G-Shock GM-2100YRA-8AER is an analogue-digital watch built around an octagonal stainless steel bezel that defines the GM-2100 line's silhouette.

The brushed silver-tone octagonal bezel frames a black dial with red markers, applied grey baton indices, and a digital window showing red digits at the right side of the dial. The 44 mm stainless steel case sits at 12 mm thick, paired with a silver resin strap on a buckle clasp, and the crystal is mineral glass.

Key Specifications

  • Movement: Quartz (battery 396 / SR726W)
  • Functions: Date, Day, Digital Time Display, Stopwatch, LED Light
  • Case: Stainless Steel, 44 mm, 12 mm thick
  • Glass: Mineral Glass
  • Water Resistance: 20 ATM - suitable for diving
  • Strap: Resin (Rubber), Silver - Universal strap

The Casio G-Shock GM-2100YRA-8AER accepts any strap labelled universal at the matching width. Because strap_width_mm is not listed in the product data, confirm the lug width against the strap before ordering.

The GM-2100 Metal Evolution

Casio was founded in 1946 in Tokyo, and the G-SHOCK line has been built around the principle of shock resistance combined with 20-bar water resistance. The GM-2100 sub-line arrived in 2021 as a direct evolution of the GA-2100 concept, bringing a metal-clad case and the now-recognisable octagonal bezel motif into a slimmer, more compact package. It sits at the intersection of the original G-SHOCK design language and metal case construction.

What the Specs Deliver

The Casio G-Shock GM-2100YRA-8AER carries SKU GM-2100YRA-8AER and runs a quartz movement paired with a digital window for a parallel analogue-digital time display in the same dial. At 20 ATM, it is rated for diving without any additional qualification. The stopwatch and day-date functions are accessed directly from the pushers on the octagonal steel bezel, and the LED light covers low-visibility reading.

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.

Buckle
Lumen

  • (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.
