about the quality of the case and waterproof, today gone to my smith to check the movement and made a correction on the balance and parts of link of the anchor, the balance had a complete perfect movement, that mean it hit each part, thinking was good, but in fact not, the balance gear could note made a 360°, so he take it of, with the anchor and made a little modification on the part remaining the anchor to correct the movement of the balance gear.
So now good balance and correction of time, 3 seconde per day, overall the movement is very good, no dust, well Lub. Decide to correct alignement of the bezel too, 120, right now perfect too, change glass of display case back by a saphir glass one, my display case back was not in saphir glass!
and at last waterproof test in slow pression and depression, why, because all the water trouble appear in slow pression and depression, not in full pressure, so first test with the crown unscrew, as it is a triple lock one, even unscrew it have to succeed and at least succeed, second test crown screw to 10 ATM at 0 during 15 minutes on depression, test succeed too.
this case is well built and the triple lock crown too, it is a good surprise, so with gaskets Lub no problem to swim with even dive
