This test was done at the SINN factory at Frankfurt am Main, Germany. The reason was, to verify the theoretical tec specs. Sinn has for this test a 1 feed (30 cm) steel tube, it contains destillated water and - first - the U2 watch. "Under pressure" - the title of the article - was up to 200 bar for 1 hour. And than - this is usually at the U-boat proofing tests - an additional test, named 125%, for 15 minutes at 250 bar. And the result: Clearly, the watch was in top conditioning, no water inside problem.

Than came the UX watch. You all know, silikon oil filled watches have theoreticily no limit ref. water resitance. The test reach in first step to 500 bar - result: no problem with a standard UX watch. And than the summit: pressure up to 1203 bar. But the problem is down to 600 - 800 bar: no Quartz movement is resist again this pressure, cause a part, the vacuum tube around the Quartz, will be destroyed. This a fact, but it is normally no probleme, cause no diver will reach deeper than 600 - 800 bar. Ok, therefore the testers take 2 different UX model: 1 case without movement (but oil filled) and 2 cases with a destroyed tube. The goal of the test for this extrem high pressure can only be, to test the case, not the Quartz movement.

And well done, both cases resist the deep of 1203 bar = 12.000 meter without problems.

And the good message for all U series is:

The crown, the bezel and the whole case are resist again this extreme pressure.

...
The goal of the test for this extrem high pressure can only be, to test the case, not the Quartz movement.
