I'm new to G-Shocks, apart from the 5600C which I've had since a kid. Since then I've cleaned it up and enjoy wearing it, and I also have a Protrek PRG-40 which I enjoy for its fabulously legible display. So they're my current 2 Casios.
Next I would like to try a Solar Atomic, and I'm thinking of either a GW-6900 or a Riseman.
Which of those two would you get, and why? I'm not intending to get both, so no easy answers there
