Feedback from Users *accumulated information from our own comments and emails, forum threads, socials, reviews, etc.

+ looks a lot more expensive than it is
+ the strap looks very comfortable
+ fits just fine and the lightweight is a plus
+ they fixed the battery indicator from the gst-b100 so it’s easier to check the battery level
+ they slimmed down the watch

– too few color/ stainless steel variants with straps without negative displays
– no backlight movement detector and timer
– no lume
– at that price it should DEFINITELY have a sapphire glass
– they removed a very useful second hand

Official Casio Description.

The GST-B500 line brings together smaller components and high-density mounting, continuing to deliver Bluetooth connectivity and solar power charging, but in an even slimmer profile. The Carbon Core Guard absorbs external shocks for true G-STEEL toughness, and the comfortable fit complements your unique way of life. Downsized button guards offer slim yet ample buttons that are easy to operate.

The bezel is treated with multiple finishes to deliver exceptional metal textures from every angle, for a truly sophisticated presentation with its own special look.
