Casio G-Shock GMA-P2100SR-7AER (add gtin)

Product Information
Overview
The polarized glass gives the GMA-P2100 a play of colors that shifts as the wrist is angled, a detail that makes the model more vibrant than many other 2100 variants. The transparent case and resin strap enhance the light, summer-like feel. The 46 × 40.2 × 11.2 mm size keeps the watch compact, while retaining the G-SHOCK series' angular design language.
Comfort
Weighing only 40 grams, the GMA-P2100 feels unusually light for a G-SHOCK with 20 ATM water resistance and shock-resistant construction. The soft resin strap makes the watch comfortable to wear for long days. The compact case is particularly well-suited for smaller wrists, and the strap size of 145 to 190 mm clearly indicates that the model is built for a slimmer fit.
Why choose Casio G-SHOCK GMA-P2100SR-7AER
The GMA-P2100 is a good choice when you want G-SHOCK toughness in a smaller and more expressive format. It features world time, timer, stopwatch, five daily alarms, and dual LED illumination, yet still feels sleek with its 11.2 mm thin profile. The color-shifting glass and transparent design give the model a distinct character within the 2100 series.
