G-Shock Mudman GW-9500 review: the Rangeman's feature list in a case you can wear under a cuff

Verdict and score
What it is built for
The same job as the Rangeman (a solar, radio-set, sealed sensor watch that never asks for a charger) for the person who tried a Rangeman on and took it off. At 56.7 × 52.7 × 14.8 mm and 81 g, per the spec sheet, it is thinner than a Pro Trek PRW-61 with a G-Shock's 200 m and mud-resistant buttons. The hunting rankings call it the treestand pick for that reason; see best G-Shock for hunting.
The duplex LCD
Casio's Pro Trek line has used a two-layer LCD that draws graphical pointers over the digits; the GW-9500 brings it to the G-Shock line. The practical effect is a compass you read like a needle and a barometer trend you read like a gauge, without switching modes. Casio's guide lists a high-brightness LED with Full Auto Light, Super Illuminator and an afterglow setting of 1.5 or 3 seconds; leave Full Auto Light off in a stand.
Power and sensors, from the guide
"Solar panel and one rechargeable battery." Approximately 6 months of operation under Casio's listed conditions (1.5 seconds of illumination and 10 seconds of beeper daily, 20 compass operations a month and the rest). Altimeter -700 to 10,000 m, barometer 260 to 1,100 hPa, thermometer -10 to 60°C, compass 0 to 359°, sunrise and sunset times with day selection, power saving and a battery level indicator. Multi-Band 6 and 200 m come from the spec sheet. Two months less stated battery than the Rangeman is the price of the slimmer module; on a wrist in daylight neither figure is ever reached.
Durability and what fails first
Carbon, resin and bio-based resin case and bezel, mineral crystal, 200 m, shock and mud resistant. The carbon reinforcement is the structural upgrade over the Rangeman's resin; the mineral crystal is the same soft spot.
Who should skip it
Anyone who wants the longest-proven Casio module and does not mind the thickness: the Rangeman GW-9400. Anyone who wants sapphire: the Mudmaster GWG-2000. Anyone who wants a track: a Garmin, per G-Shock vs Garmin Instinct.

Good to know
Mineral crystal, not sapphire; the Rangeman lives behind a raised bezel for a reason.

How we scored this
What we checked to build this ranking
Every pick here is researched against the documents that decide whether a watch lasts: the maker's own battery table read mode by mode, what the lens and case are actually made of, the water rating, whether a MIL-STD-810 line is on the record and in whose words, and how long the maker keeps updating the line. Each one is then scored on a public rubric weighted for a decade of ownership, and every figure links to where it came from.
That is why the order on this page is worth following: it is built from specs you can open yourself, and commissions never set a score or decide a pick. The rubric and its weights are published.
