What do these pressure test results mean?

I am wondering what these numbers mean? I am hoping to be able to bring my 1980s Day-Date in the pool with me. Nothing too intense. Just want to be sure it is sealed? May someone be kind enough to translate these numbers for me? Thanks!!

Test pressure : -0.7 bar
Maximum deformation: -7.91 um
Tightness value- +0.4 %/min
Testl okay
:
Test pressure : + 10 bar
Maximum deformation : +149.86 um
Tightness value : +8.5 %/min
Test2 okay

Well friend admittedly I don’t know what those numbers mean but I see “okay” twice so it looks like you’re good to go!

Looks like the first set is a vacuum test (good) and second set is 10 bar (100m) test (good). Enjoy the pool!

Deflection is the amount the crystal displaces when subjected to the pressure.
