Introducing the new GA-B001 series from G-SHOCK, featuring a new toughness-driven design and Smartphone Link functionality. Casio brings ingenuity to the exterior structure to achieve an integrated bezel and band construction in a shock-resistant watch which comprises two separate components that connect at the 9 and 3 o'clock positions. The molded construction follows the lines of the wrist, minimizing the space between the wrist and watch for an enhanced fit. These watches are equipped with a Mobile Link feature for pairing with a smartphone via Bluetooth®. When used with the dedicated CASIO WATCHES app, the watch automatically adjusts to the correct time. The App information function sends notifications on the watch when the app receives updates on new products and other information. The GA-B001-4AER features a new shade of red. This watch is designed for those who appreciate a blend of style and functionality. It offers both analog and digital display options, with a durable resin bracelet in striking red. The watch has a black dial and mineral glass for a sleek finish. With water resistance up to 20Atm, this watch is perfect for everyday wear and adventurous activities. Special functions include G Shock-Carbon Core Guard, Smartphone Link, Chronometer, Alarm, Timer, Automatic Time Adjustment, and a Telephone Search Engine.
