2ATM (20m/66ft) Naturalist Model Submersion Test #1

*So after having a tank fail, multiple camera issues I gave up and just made a timelapse of the last 8hrs of a 10hr test. This will be a temp vid until I can figure out what the issue is with the camera.

Multiple hour submersion test in progress. Changes from previous tests;

Different gasket material
2ATM (20m/66ft) (up from 1ATM in previous test)
Placed smartwatch in water then pressurized the chamber

The third item is key. This is a direct simulation of real world exposure. Either way, the modifications I have made have already put the watch well beyond any touchscreen smartwatch and into the shallow end (pun intended) of traditional watch water resistance territory. I will update this section once the test is complete and I’ve compress about 12hrs of video into something a lot shorter.

Results:
I had opened the smartwatch every time I had to stop the test and did not properly seal it. From a traditional watch standpoint this is a big no-no. However, after multiple 3-4hrs immersions at pressure the inside was bone dry.

As you can see here the pump was attached the whole time for the longer test. I did not remove the pump fast enough at the end causing a rapid decompression. This may have resulted in water intrusion at the very end as the cotton pad inside the watch showed sings of water intrusion.

Conclusion
Inconclusive for time periods beyond 3-4hrs of immersion and needs to be rerun. Still, no water intrusion at the 3-4hr mark on multiple occasions.
