Casio G-Shock watches are always designed to look good, but many of them are also crammed with technological features that can be used to help those who use them for training purposes. The Casio G-Shock GBX100-1 is one of the G-Shocks that fits squarely into this category. This G-Shock has plenty going on in the looks department. It includes a black resin base with a matching black resin band and a stainless-steel bezel. It also has a crystal-clear digital display with a Super Illuminator LED backlight that makes it shine when you push the button on the front of it. But our experts like what they see when they dig a little deeper while looking at this G-Shock. It's shock-resistant and water-resistant up to 200 meters, and it has a special training function that will let you track everything from your speed to your average pace while wearing it. You can also sync it to your smartphone using Bluetooth and the G-Shock Move app. The Casio G-Shock GBX100-1 was released in May 2020 when it retailed for $160.
