  • G-Shock GA2100GB-1A Black One Size

Description

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 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 packs all this protection into a comfortable watch whose sleek, thin profile is magnified by its dark styling. Features of the G-SHOCK GA2100 Thin Watch Technological innovation abounds in the compact case of the GA2100. World Time displays the time in 31 time zones (48 cities), great for coordinating global business or keeping in touch with distant family and friends. A stopwatch, timer, and five daily alarms help you to organize your day, keep track of important ongoing tasks such as cooking and project time tracking, and stay focused without the need to shift your attention to a screen. The stopwatch offers elapsed time, split time, and 1st and 2nd place times. Keep an eye on your children's screen time with elapsed time or utilize the split time to measure various segments of an important presentation and track segment pacing in a natural flow. The GA2100-1A can become an integral part of your daily organization and task completion. This thin watch combines bold style with daily functionality.

  • Dial is pink.
Color: Red
Was definitely interested in the red and black color. Not a fan of the dial color which I was hoping was more red than pink. When people make fun of me, I will just tell them the dial is red. Seems a little undersized also compared to what the listed size is. I'll keep it and possibly give it to my wife. Great looking watch though overall. Time setting is easy if you've had a G shock and it seems durable. ... show more
