For over 25 years, G-Shock has been making shock-resistant, waterproof, long-lasting wristwatches. Manufactured by Casio, G-Shock watches are digital-first, and all feature a stopwatch, countdown function, backlight, and water-resistance. From there, the tech only gets better. From the Bluetooth-enabled GBA400 G’Mix App, to atomic clock-synchronized, solar-powered watches like the GDX6900, GA-100, and DW-5600 ‘90s, G-Shock watches are collectors items. And with colors that range from black to white, red, yellow, and camouflage, you can never have too many.
