Casio G-Shock CasiOak wristwatch, gray plastic, GMA-P2100SR-1AER
Gray translucent Casio G-Shock CasiOak watch with a green dial that changes shade with the light
The green dial changes shade depending on the angle at which light hits the coated mineral glass. Around the dial is a smoke-gray, translucent case and a strap in the same color. In the picture, the dial has dark green hour markers, and in addition to the analog hands, there is a small digital display at the bottom.
This Casio G-Shock belongs to the CasiOak series and has been made more compact than before. The case is 40.2 mm wide and 11.25 mm thick, and the watch weighs 40 g, so it also suits a narrower wrist. The polyurethane strap fits a wrist of 145–190 mm. Water resistance is 200 m / 20 atm: you can swim, snorkel and do water work with the watch, but it is not suitable for scuba diving. The watch has world time, an alarm, a stopwatch and a light, and the hands can be moved out of the way of the digital display. G-SHOCK started from the shock-resistant watch developed by Kikuo Ibe in 1983.
