Casio G-Shock Men's Black Watch GBA-900-1AER

Introducing the latest G-SQUAD additions to the GBA-900 Series of Smartphone Link timepieces.

This model can measure distance using an accelerometer while linked with the GPS function of a smartphone via Bluetooth. Once you take measurements with a smartphone, the next time you will be able to measure distance with the watch alone. Distance and running time measurements are used to calculate your pace, and an auto lap feature automatically records the time it takes to cover a specific distance. You can also check your activity history by linking with an app running on your smartphone. The app also helps to simplify the configuration of watch settings and training management. A 5-level exercise intensity graph and a daily goal attainment rate help keep you motivated.

Super Illuminator faces illumination keeps face information easy to read, even in the dark. The band’s soft urethane material improves the fit to the wrist, and vent holes improve breathability. This watch connects with your phone via Bluetooth to support auto time adjustment, phone notifications, step tracking, and other functions throughout the day. Battery life is approximately two years between replacements.

G-SHOCK’s origin is the story of an unwavering belief that inspired a relentless quest and produced a tough spirit that promises never to fade away. Born from a dream of "creating a watch that never breaks. "It was over 30 years ago, a CASIO engineer won the battle against the laws of nature. He designed a watch that would resist centrifugal and impact forces, as well as high water pressure. Since then, the name G-SHOCK has become a byword for independence and pushing the limits. G-SHOCK watches stand out not just with their tough design, but also with their technical refinements. From environmentally friendly solar technology and Bluetooth® through to GPS and radio technology — G-SHOCK always features state-of-the-art technology.
