FOC Wet pressure test for watches
I always like to know if my watches (many vintage) are water resistant, so I acquired a wet tester (up to 5ATM). I believe many people here also "question" their watch resistant qualities of their older watches thus I am thinking of helping out and provide a FOC service to members here .
My tester looks like:

except mine goes to 6ATM (but I prefer to cap it at 5ATM).
