Description
The Casio G-SHOCK GMA-S2100RB-1ADR is an analogue-digital watch with a 46.2 mm octagonal resin case, a red dial and a resin strap with a pin buckle, finished in a resin and carbon bezel that gives the whole case a uniform, moulded look.
Case & crystal
The octagonal case is moulded in resin, and the bezel pairs carbon with resin for a rigid, low-glare surround. The case measures 46.2 mm across and 11.2 mm thick. The case and the strap are both resin, so the watch reads as a single, continuous piece. A mineral crystal protects the dial.
Dial
The red dial carries an analogue-digital display with Neobrite luminous hands, so the lume stays legible in low light. A digital display window and a small sub-dial sit within the layout, keeping the digital readout separate from the hands.
Movement
This is an analogue-digital movement with four functions: alarm, World Time, stopwatch and a backlight for reading the digital window in the dark. Explore more Casio watches in the same family.
Bracelet & fit
The resin strap fastens with a pin buckle, which allows you to set the fit hole by hole for a secure hold. Resin is a light, flexible band material that suits daily wear.
On the wrist
At 46.2 mm in diameter and 11.2 mm thick, the case has noticeable wrist presence and a sturdy case profile. It is listed as a women's watch and suits those who prefer a larger, sports-minded watch. It fits everyday, casual and outdoor use better than formal dress. Browse all watches if you would like to compare sizes.
Water resistance
The watch is water resistant to 200 m. In plain terms, that means it is built for swimming, snorkelling and rinsing off after a day outdoors. When the time comes, our team can help with watch servicing and repairs. The piece is covered by the manufacturer's warranty: 1-year international Casio warranty.
To see the red dial and resin case in person, try it on at our Mall of the South and Greenstone showrooms.
