Orient Automatic Crystal and Bezel

[Simeon]

I have had a few issues with my Orient Automatic crystal and bezel. The bezel came off with a case knife and I haven't been able to refit it. Doing a bit of research on here, I think that it is an arrangement where the crystal is snapped over a lip on the caseback and then the bezel is installed over the top like a tension ring. I have managed to crack the crystal trying various attempts to press it onto the case.

Measuring the crystal with Vernier calipers, I think it is a Sternkreuz XS 314.171 but I can't correspond that to the reference/ case number on the caseback. I also measured the outer diameter of the lip on the case that it may fit over and this is 30.5mm, which is actually 0.7mm bigger than the static inner diameter. Is it likely that the crystal can be expanded enough to snap over that? The inner diameter of the bezel/ tension ring is 32.2mm which works with 31.4+0.7 = 32.1mm

Does this sound correct? What method should I use to snap the crystal and then bezel into place? I have a cheap case back press with nylon dies but I managed to break the old one with this method.
