[2470f2.8ii]

Looking to get a prof xtal on my PAM 508

Prof asked me to measure it to see if he has one to send. I'm a little nervous I'll screw that up with my ruler. Anyone know?

ThankS!

I want your watch and I want his crystal if you find out or just give it a go with you're best measurement, please let us know.

It was custom though so I think I have a few more weeks of waiting

Someone on rwg did a vernier caliper and got 34mm
checks out with my at home trial:

Prof just told me 33.5 --- so I'm guessing that's the final answer
