Casio G-Shock CasiOak Bluetooth Solar Analog Digital GA-B2100-3A Green Dial 45.4mm Resin Strap Men's Watch

The Casio GA-B2100-3A represents a monumental upgrade to one of the most beloved silhouettes in the "G-Shock" lineup, universally celebrated by the watch community under its "CasiOak" nickname. This specific model retains the iconic, retro-inspired octagonal bezel but introduces highly anticipated modern technology beneath the surface. It features a perfectly proportioned 45.4mm Carbon And Resin Case executed in a deep, utilitarian forest green. Thanks to Casio's advanced Carbon Core Guard structure, the watch maintains an incredibly slim 11.9mm profile, ensuring it remains as comfortable and wearable as the original while delivering absolute, uncompromising shock resistance. The dial is a sophisticated, highly legible Green Analog Digital Display that seamlessly blends classic hands with a modern LCD screen. A key update in this "B" (Bluetooth) variant is the reimagined sub-dial at the 9 o'clock position, which now elegantly indicates the current mode and battery level. The bold, three-dimensional hour markers and hands are treated with Neobrite, while a Super Illuminator double LED light guarantees brilliant visibility in complete darkness for both the analog face and the digital readout. The dial is deeply recessed and protected by a robust, scratch-resistant Mineral Glass crystal. At its core, this indestructible timepiece is powered by Casio's highly efficient Tough Solar Movement, which constantly charges the battery using any available light source. Furthermore, it boasts a Bluetooth Smartphone Link, allowing you to seamlessly connect the watch to the Casio Watches app for automatic, pinpoint time syncing anywhere in the world, effortless alarm setting, and a handy phone finder feature. Secured by a durable, matching green Resin Strap and boasting the legendary G-Shock 200-meter water resistance, the GA-B2100-3A is the ultimate zero-maintenance, high-tech daily companion.
