Thanks for the advice.
I finally got around to fixing my watch. Turns out it was pretty simple.
I machined a piece of teflon with two concentric holes in it -- one that was just larger than the crystal, and one that was just larger than the bezel -- to hold the bezel while I pushed out the crystal.
I machined a second piece of teflon to push out the crystal that was just smaller in diameter than the number ring.
(Teflon was used because it is slightly compliant and does not scratch the metal or crystal.)
I pushed the crystal out and it was then obvious how the assembly came apart and subsequently went back together...
You were correct in assuming there was another ring -- not an o-ring, but it looked like a teflon ring both under the bezel assembly and just under the crystal.
When I put it back together, I put a VERY small drop of blue lock-tite into the screw holes that hold the bezel assembly onto the case. Once screwed back together it was just a matter of placing the number ring back in, the teflon ring ontop of that and then pushing the crystal back in.
Once again, thanks for the advice. It turned out to be pretty simple, but I probably wouldn't have dared the 'extraction' without a little direction.
Cheers
