I find that the design of the interface of the watch is one of the best that Casio has ever designed. The only thing that I would change is the display of the time, that maybe I would make it a bit bigger.
At the bottom part you can find a window with the time and just above it there is the month-day date.
There are three circular windows on top of the window time. The left shows you the time as an analog watch. The centre one shows you the mode which are you in and if the alarm or signal is activated. The right window shows you a second’s display.
It would be great that Casio updated this watch with the tough solar and the atomic timekeeping, without changing the design. Maybe one day I recreate a possible GW-5900 with Photoshop or in 3D.
In conclusion, a great classic that has a few drawbacks but that in my opinion kick some ass to newer G-Shock designs. It lacks of illuminator, one thing that you can really miss, but we have to remember that we are talking of one of the oldest G-Shock designs and technology.
As always, I hope that you enjoyed this review!
