This multi-mode precision instrument needs no babying. It teams impact-resistant G-Shock technology from Casio® with wayfinding and weather prediction functions. A shielded button takes you directly to the sensor screens; each mode has an audible tone so you don’t have to take your eyes off critical matters while cycling through functions. Compact sensors keep the whole package lightweight, and atomic timekeeping and solar power let you go off the grid indefinitely without losing accuracy.

• Multi-band atomic timekeeping calibrates from radio signals.
• Digital compass displays direction as one of 16 points with 60 seconds continuous measurement. Also has graphic direction pointer, bidirectional calibration, declination correction and bearing memory.
• Altimeter measures -700m to 10,000m in 1m increments. 40 record capacity, high/low altitudes, auto cumulative ascent/descent, and altitude differential.
• Barometer has a display range of 260 to 1,100 hPa with a pressure tendency graph and change indicator.
• Thermometer displays -10 to 60°C in 0.1°C increments.
• Full auto LED backlight with afterglow.
• Sunrise and sunset times.
• World time with 31 time zones (48 cities + UTC), city name display, and daylight saving on/off.
