Awesome look
Disappointed in Jax

Purchased this watch for the look. Looks great with great features. I was like a kid at Christmas waiting for it to arrive. The watch after setting up would only stay connected to Bluetooth for three minutes then disconnect . The only way to get it to reconnect was to unpair it, delete the app, download the app again, re- pair the watch and completely set the settings up all over again. Did this seven times. Even tried it on my wifes iPhone 12 same issue. Spoke with Casio customer service tried a full reset to no avail. Determined defective. For $380 you would think you could get a watch that works, very frustrating. REI was great and took the return to be returned to Casio. Love REI !!! I’ve read a similar review on another model which adds the heart rate monitor so I’m hesitant to try another. G Shock.

Awesome watch that is built to take a beating. A lot of cool features and plenty to learn more about for sure. I feel like I’m ready to handle the elements or some great adventure rocking this, and all while not having to worry about it getting destroyed.
