This is a very cool GLX5600 “surf watch” with a tide level and moon phase indicator. Of course, you don’t have to surf to appreciate the functionality or the aesthetics. In my opinion this is one of the most interesting variations on the classic G-Shock square, with great looks (note the subtly striped silver dial surround) and all the normal and really useful G-Shock features. The main display is still large and legible and the moonphase/tide display doesn’t flash like on some other GLX models (which is really distracting). The perfect do-it-all Square? Maybe! I’ve had three of them, I keep buying them and they keep getting bounced out of my collection by something else (in this case, a circa 1980 digital Marlin). I’ll probably buy another! But for now, it’s for sale.
