I like the shoebill colors more than the size of this Mudman

G-Shock: 62/120 bezel clicks. Mudman Earthwatch Japan shoebill

The colors are the best part of this Mudman for me. That blue-gray case with the small gold accents is a really good combination, and I like the way it came from the shoebill's feathers and beak. It feels more considered than choosing another bright color and putting a charity name on the strap.

The watch itself is still a lot. The broad protective case, the sensor display and all the lettering make it busier than the square G-Shocks I usually want. I can like the treatment and still know I probably wouldn't pick this shape for myself. A long feature list doesn't make that preference disappear.

The shoebill-inspired Mudman

This is the GW-9503KJ-2JR, an Earthwatch Japan collaboration. Casio says part of the sales supports the organization's activities. The watch uses blue-gray around the case, gold around the display and front button, and a lighter keeper on the strap. There are special strap, backlight and packaging details as well.

The case measures 56.7mm long, 52.7mm wide and 14.8mm thick, weighing 88g. That is a large object, and the side structures are part of its appearance. I wouldn't reject it purely for diameter, especially within G-Shock, but I would definitely want to see how far those sections extend across my wrist.

Tough Solar and Multiband 6 radio correction are both listed. Those are the useful features that tend to interest me most in a G-Shock. It also has a compass, altimeter, barometer and thermometer, with mud resistance, Carbon Core Guard and 200m water resistance. The glass is mineral, and the metal bezel has a blue-gray ion-plated finish.

Useful technology, a shape I struggle with

I like the idea of a solar watch that corrects its own time. That is the kind of convenience I would notice even if I never used the other sensors. I am less sure that I need the full instrument panel around the time display. I haven't tested the sensors or used this exact model, so I can't judge their behavior from the pictures.

The coating is something else I would think about over a long ownership period. I like the color now, but I would want to understand how the bezel looks after years of knocks. That is an unanswered durability question, not a claim that this particular finish will fail.

Casio lists a Japanese retail price of ¥64,900 including tax. Time Station NEO gives November 13 as its planned Japanese release. A confirmed US price and US order date are unknown as of November 3, 2026.

I give it 62 out of 120 bezel clicks. The color palette and solar/radio combination make me look twice, but I would still choose a simpler square for my own wrist.
