I have been wondering the same thing. I was able to get a 2.15 x 0.75 mini o-ring from an assorment in the crown of my Autavia and 1.7 x 0.5 mini o-ring in the pushers. I left the movement out and it passed the static bucket test. I'm going to stop by my local watchmaker that I'm sort of learning from and have him pressure test it for me. I will let you know the results.

I'm not ready to go diving with it but at the very least I know that the the watch is safe from rain,handwashing,etc.

: Does anyone have a source for replacement crown seals for the
