Casio G-Shock Master of G-Land Mudman Series in Black #GW9500-1
This watch features a 56.7 × 52.7 × 14.8 mm case and weighs 81 grams, offering a rugged yet lightweight feel on the wrist. The case and bezel are crafted from bio-based resin and paired with a matching bio-based resin band. Built with shock resistance, mud resistance, and a Carbon Core Guard structure, it is designed to withstand demanding environments, while 200-meter water resistance ensures reliability in and around water. It features radio-controlled timekeeping with Multi Band 6 for precise automatic time adjustment and is powered by Tough Solar technology for dependable solar operation.
Equipped with advanced sensors, the digital compass measures and displays direction in 16 points with a range of 0 to 359 degrees in 1-degree increments. It offers 60 seconds of continuous measurement, a graphic direction pointer, bidirectional calibration, magnetic declination correction, and bearing memory for accurate navigation.
The altimeter measures from -700 to 10,000 meters (-2,300 to 32,800 feet) in 1-meter (5-foot) increments and allows manual memory storage of up to 30 records, including altitude, date, and time. It also provides auto log data for high and low altitudes, cumulative ascent and descent, and trek log data for up to 14 individual treks. Additional features include relative altitude readings from -3,000 to 3,000 meters, selectable measurement intervals of 5 seconds or 2 minutes (with 1-second intervals for the first 3 minutes), and the ability to switch between meters and feet.
The barometer displays atmospheric pressure from 260 to 1,100 hPa (7.65 to 32.45 inHg) in 1 hPa (0.05 inHg) increments, and includes a 42-hour pressure tendency graph, pressure differential graphic, and a barometric pressure tendency alarm that signals significant changes. Units can be switched between hPa and inHg. Completing the sensor suite, the thermometer measures temperatures from -10 to 60°C (14 to 140°F) in 0.1°C (0.2°F) increments, with selectable Celsius or Fahrenheit display.
