• G-Shock GXW-56 Military Toughness Test

    More proof (if proof were needed!) that G-Shocks are tough - very tough. Casio USA have sent three G-Shock GXW-56 off to be tested thoroughly at Garwood Labs who normally deal with military, space and aviation testing. The G-Shocks were subjected to twelve tough tests and passed them all, read on for the full results.

    Test 1 - Altitude test
    Subjected to 4572m (15000ft) simulated altitude for one hour - passed

    Test 2 - High temperature
    Subjected to 65.5C (149.9F) for four hours - passed

    Test 3 - Low temperature
    Subjected to -20C (-4F) for four hours - passed

    Test 4 - Blowing rain
    Subjected to simulated blowing rain at 64.37 kph (40 mp) for 30 minutes - passed

    Test 5 - Random vibration
    Subjected 20-1Khz - passed
    Subjected 1Khz - 2KHz - passed

    Test 6 - Freeze / Thaw
    Subjected to freeze then thaw conditions cycling between 0C and 10C with 99% humidity (i.e. wet) ands prayed with water - passed

    Test 7 - Humidity
    Subjected to cycling between 60C and 30C with 95% humidity - passed

    Test 8 - Solar radiation
    Subjected to Irradiance Modulation Range: 0W/m to 1120W/m applied during temperature ramp and soak
    - passed

    Test 9 - Immersion
    Subjected to 1m depth for 30m minutes - passed

    Test 10 - Salt spray
    Subjected to salt spray for 24 hours - passed

    Test 11 - 10m drop
    Dropped onto plywood, concrete and steel from 10m - passed

    Test 12 - Blowing dust
    Subjected to blowing dust for 13 hours - passed

    Full results and details can be found here on the G-Shock US site. Great range of tests, the only obvious omission is an absolute depth / pressure test.

      This test is good, but it should be even more extreme. Why not test at -30 F, and explain how much abuse the crystal can take?

      I have this G-shock. Wish that Casio would release a newer model version of the King G.
