Reviewed in the United States on August 22, 2023
I don’t own anything this bright in color. I was a bit nervous at first but have been in the mood for the something colorful, all my other g-shocks are black or gray. Wow. The yellow of the strap pops, and the the white indices make a fantastic contrast. Definitely a looker! Great size and very comfortable! Easy Bluetooth setup through Casio Watches app as well! Most definitely recommend!
