The GA2100 line by G-SHOCK has been an unmitigated success since its launch in 2019. Combining a thin case that lives up to G-SHOCK’s standards of toughness with a stripped-down ana-digi dial, and a distinctive octagonal shape, its appeal is undeniable to both fans of the brand and those just looking for a solid sports watch. Now for 2022, G-SHOCK returns to the format for the GAB2100 with some logical upgrades: solar charging and Bluetooth connectivity. The best got better.

Solar speaks for itself. G-SHOCK’s Tough Solar tech allows the watch to charge in the sun, turning your outdoor activities into perpetual power. Bluetooth connectivity then adds a ton of features via G-SHOCK’s mobile app. Automatic time adjustments, reminder settings, time + place logs, and more, in addition to the standard alarms and timing functions.

Visually and physically, luckily, the GAB2100 stays true to the original. Measuring 45.4mm × 48.5mm x 11.9 mm, and weighing 52g, it will wear just as well as the GA2100, providing a bold presence, but a comfortable feel. The dial features a layered design with large applied markers, bold hands, and a convenient LCD display in the bottom right quadrant. What was a sub-dial for the day of the week has then been replaced with a mode indicator for greater convenience. A rubber strap and bezel protects the Carbon Core Guard case and a mineral crystal keeps out the dust.
