With its black analog-digital dial and gray indices, the G-SHOCK GA2100-1A watch sports advanced G-SHOCK protection with a thin and comfortable watch case. The iconic 2100 series was introduced in 2019 and quickly became one of G-SHOCK's most popular lines of thin watches. An octagonal bezel gives the GA2100-1A its sophisticated appeal, and the black dial combined with a negative digital display presents a dark backdrop for the eye-catching gray indices and hands. A slim and elegantly contoured watch that complements your attire with or without sleeves, this GA2100 offers a dark charismatic coupling of modern style and absolute toughness.

A Thin Watch with Signature G-SHOCK Toughness

At only 11.8mm thick, the watch case creates a slim profile that makes the 2100 series a comfortable everyday watch. Although wonderfully thin, the GA2100-1A doesn't skimp on protection. G-SHOCK innovative design utilizes a Carbon-Core Guard Structure that begins with an advanced carbon fiber-reinforced resin case. The entire GA2100 series maximizes the utility of a compact design while advancing the G-SHOCK legacy for crafting some of the toughest watches on the planet. 200-meter water resistance (wr 20 bar) and scratch-resistant mineral glass round out an incredible array of protection. Weighing only 51 grams, the GA2100-1A packs all this protection into a comfortable watch whose sleek, thin profile is magnified by its dark styling.
