Casio G-Shock “Torture Test”: Soaking the Casio G-Shock GA-700 in Boiled Water

Our earlier freeze test from 24 April 2017 to 27 April 2017, Casio G-Shock “Torture Test”: Freezing the GA-700, proved that this Japanese watch can indeed withstand the sub-zero temperatures.

We had wondered if Casio G-Shocks are able to survive thermal shocks. Having passed the extreme cold test, it was now time to assess the very same Casio G-Shock GA-700’s ability to withstand high temperatures.

On 28 April 2017, a day after the Casio G-Shock GA-700 survived the extreme cold, we put it through the first of two high temperature tests.

In the extreme heat test, we first placed the Casio G-Shock GA-700 into a container, the very same one used for preparing instant noodles. We then added a raw egg before pouring in boiling water.

The video above details the extreme heat test with the Casio G-Shock GA-700 soaking in boiled water. The test began at around 10.46pm.

Two minutes after sitting in boiled water, the digital display of the Casio G-Shock GA-700 begins to fade. A minute later, nothing is shown on the digital display.

Was the heat too much for the Casio G-Shock GA-700?

Even though the digital display had no readouts, the Casio G-Shock GA-700 still had a healthy heartbeat as its analog minute hand continue to move.

Ten minutes into its “hot bath” the digital readouts begin to reappear. Well, actually, the “hot bath” was beginning to cool.

However, condensation was detected between the 11 and 12 o’clock positions.

After around 20 minutes in the “hot tub”, the Casio G-Shock GA-700 was taken out.

Condensation was discovered in another area, between the 7 and 8 o’clock positions. Over a few minutes, the condensation cleared up.

The initial plan was to soak the Casio G-Shock GA-700 for 3 minutes in boiled water. However, the GA-700 sat in boiled water for 20 minutes instead. Photo: © TANG Portfolio / TimeWerke. Elfa / Timmy.

The resin case of the Casio G-Shock GA-700 did not melt and the watch continued to function well.

The Casio G-Shock GA-700 had passed the first of the extreme heat thermal shock tests.
