Casio G-Shock Men’s Green Bluetooth Analog-Digital Watch Tough Solar

The Casio G-Shock G1244 GA-B2100-3A brings modern technology to one of G-Shock’s most recognisable designs. Its slim octagonal profile takes inspiration from the original G-Shock design concept while adding solar charging and smartphone connectivity for a more practical everyday experience. The rich green resin exterior is paired with a dark analog-digital dial, giving the watch a military-inspired, sporty appearance without making it overly bulky. The layered dial construction adds depth, while bold hands and indexes make the time easy to read.

At the heart of this model is Casio’s Tough Solar technology. Light is converted into energy to keep the rechargeable battery powered, making the watch convenient for regular long-term use. The GA-B2100-3A also includes Bluetooth Smartphone Link. When paired with the CASIO WATCHES app, it provides automatic time adjustment, easy watch settings, access to approximately 300 World Time cities through the app, Time & Place, reminders and a useful phone finder function. Durability comes from the Carbon Core Guard structure, which uses a carbon-fibre-reinforced resin case to protect the internal module while keeping the watch lightweight. The model weighs only around 52 g, making it surprisingly comfortable considering its rugged appearance. The watch measures approximately 48.5 × 45.4 × 11.9 mm, maintaining the relatively slim profile for which the 2100 Series is known. A resin band complements the lightweight construction and sporty styling.
