G-Shock Mudman GW-9500 has a Pro Trek-style duplex LCD display, Triple Sensor, Solar-Radio Timekeeping

Casio officially announced its latest Master of G series: the G-Shock Mudman GW-9500. The series is scheduled to be released in Japan on July 14, 2023, with a tax-included price of 55,000 yen per model, with details for other countries to be announced. (The U.S. price is expected to be around $380.) The launch models include the black GW-9500-1, orange and black GW-9500-1A4, and green and black GW-9500-3. The module number is 3553, and according to the case back covers, these models are made in Thailand.

The GW-9500 has a Carbon Core Guard structure measuring 56.7 x 52.7 x 14.8 millimeters and weighing 81 grams. Although it initially looks large with its rugged bezel guards, the watch has a reduced bezel height and is relatively thin compared to other Master of G models. The previous Mudman G/GW-9300 is 50.8 mm wide 18.2 mm thick, and the Rangeman GW-9400 is 53.5 mm wide and 18.2 mm thick. The case, bezel, and band of the GW-9500 are made of bio-based resins.

The GW-9500-1A4 and GW-9500-3 are the first Casio watches with both a duplex display and an inverted style of display. Instead of the colored pointers seen on the GW-9500-1, the pointers on the inverted models appear in a similar shade as the digits.

The Master of G line includes advanced professional-grade watches like the Mudman, which is shock-resistant, mud and dust-resistant (including the protected cylindrical buttons), and water-resistant to 200 meters. The GW-9500 has Tough Solar power with a power-saving function and Multi-Band 6 for automatic time adjustment if within range of the six radio transmitters located in North America, Europe (2), China, and Japan (2). The Triple Sensor includes a pressure sensor with an altimeter and barometer, compass, and thermometer. The duplex LCD includes a layer with pointers that is used for compass bearing readings (including a bearing memory to point to a target destination) and the barometric pressure differential indicator.

Like the previous Mudman series, the GW-9500 is ideal for use in harsh environments, and the expanded features that are comparable to the Rangeman GW-9400 make it the most advanced Mudman watch.

Like the Rangeman GW-9400, the GW-9500 has sunrise and sunset time display. Other features include world time, 1/10-second stopwatch, countdown timer (24 hours), 5 daily alarms with 1 snooze, hourly time signal, full auto LED backlight (with selectable duration), full auto-calendar, and button tone on/off.

Other than the large duplex display, a major difference between the GW-9500 and the Rangeman GW-9400 is that the Rangeman has a 40-record manual memory (with a dedicated time stamp button) for saving altitude, barometric pressure, temperature, bearing, and time data. The GW-9500 does not have this, but it does have the auto log data function for the altimeter and trek log data for 14 altimeter records (including high/low altitudes, auto cumulative ascent and descent). The Rangeman also has a dedicated button to start the stopwatch from timekeeping mode, and the stopwatch measures in a more precise increment of 1/100-second versus 1/10-second for the GW-9500.

The Rangeman GW-9400 was not originally listed as being mud-resistant, but it was previously labeled and marketed as such by Casio America. It was the first G-Shock to feature the protected cylindrical button structure seen on the GW-9500 and the Mudmaster line.
