Casio G-Shock Master of G-Land GW-9400 Series in Black #GW9400-1

This watch features a large 55.2 × 53.5 × 18.2 mm case and weighs 93 grams, delivering a bold and rugged presence on the wrist. The case and bezel are constructed from durable resin and paired with a matching resin band, all built with shock-resistant construction and 200-meter water resistance for serious outdoor performance. It features radio-controlled timekeeping with Multi Band 6 for precise automatic time adjustment and is powered by Tough Solar technology for reliable solar operation.

Designed for adventure, it includes a built-in altimeter with a measuring range of -700 to 10,000 meters (-2,300 to 32,800 feet) in 1-meter (5-foot) increments. The altitude memory function stores up to 40 manual records with date, time, direction angle, altitude, barometric pressure, and temperature, along with auto-save data for high altitude, low altitude, cumulative ascent, and cumulative descent. It also provides relative altitude readings from -3,000 to 3,000 meters and offers selectable measurement intervals of 5 seconds or 2 minutes (with 1-second intervals for the first 3 minutes), plus meter/feet conversion.

The built-in barometer displays atmospheric pressure from 260 to 1,100 hPa (7.65 to 32.45 inHg) in 1 hPa (0.05 inHg) increments, with a 42-hour pressure tendency graph, pressure differential graphic, and a pressure tendency alarm that signals significant changes. Units can be switched between hPa and inHg. A digital compass measures and displays direction in 16 points with a 0 to 359° range in 1° increments, offering 60 seconds of continuous measurement, a graphic direction pointer, bidirectional calibration, magnetic declination correction, and bearing memory.

Additionally, 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, making this watch a fully equipped tool for demanding environments.
