Mil-Spec Watches & Testing

Mil-Spec Watches & the MIL-STD-810 Tests

Tested to military standards defined by US Department of Defense MIL-STD-810, these five G-SHOCK models demonstrate excellent durability under simulated environmental and mechanical conditions associated with military, law enforcement, and outdoor use. All five models are part of the G-SHOCK military watches collection and were tested by Element, an independent testing and certification laboratory, in Boxborough, MA.

Element collaboration

The twelve environmental tests these five models underwent provide further validation that these G-SHOCK models are able to withstand the harsh conditions the tests are designed to simulate.

MIL-STD-810 Environmental Testing of Mil-Spec Watches

Below are the specific MIL-STD-810 tests completed by each of the five G-SHOCK models:

  1. Salt Fog

    Testing evaluates durability and corrosion resistance when exposed to salt-laden atmospheric conditions.

  2. Humidity / Aggravated

    Testing evaluates durability under elevated humidity and temperature conditions designed to accelerate moisture-related stress.

  3. Freeze / Thaw

    Testing evaluates durability when exposed to repeated freezing and thawing conditions.

  4. Low Pressure / Altitude

    Testing evaluates performance under reduced air pressure conditions associated with high-altitude environments.

  5. High Temperature

    Testing evaluates performance and durability under elevated heat conditions.

  6. Low Temperature

    Testing evaluates performance and durability under cold-temperature conditions.

  7. Solar Radiation

    Testing evaluates durability when exposed to simulated sunlight and solar heat.

  8. Blowing Rain

    Testing evaluates resistance to wind-driven rain exposure.

  9. Immersion

    Testing evaluates resistance to water exposure when temporarily submerged.

  10. Random Vibration

    Testing evaluates durability under irregular vibration stresses that simulate demanding movement or transport conditions.

  11. Mechanical Shock

    Testing evaluates resistance to sudden impact, acceleration, or drop-related forces.

  12. Sand & Dust

    Testing evaluates durability when exposed to airborne particles that may affect operation or exterior components.

With this battery of tests, G-SHOCK mil-spec watches demonstrate their reliability and dependability in the brutal environmental conditions these tests are designed to simulate. Explore the G-SHOCK technology that put these military-grade watches up to the challenge. More details on the tests performed in the MIL-STD-810 Overview of Testing Procedures section.

Proof Point

Built for Sudden Impact

Mechanical shock testing highlights the G-SHOCK promise of toughness under abrupt stress, acceleration, and drop-related forces.

Watch the G-SHOCK MUDMASTER GGB100XM-1A Excel in MIL-STD-810 Testing

G-SHOCK filmed five of the twelve tests, while the GGB100XM-1A completed all twelve. While all five models completed the same twelves tests, only the GGB100XM-1A was filmed.

Video transcript: The video opens on a close-up of the G-SHOCK Mudmaster GG-B100XM-1A with the words “Military Spec MIL-STD-810 Testing” overlaid on screen.

Test-lab footage shows the watch undergoing MIL-STD-810 evaluation sequences. The video reinforces that G-SHOCK filmed five of the twelve tests, while the GG-B100XM-1A completed all twelve tests.

The sequence closes by positioning the Mudmaster GG-B100XM-1A as a G-SHOCK mil-spec model tested for demanding environmental and mechanical conditions.
