Just curious, does anyone have the diameter for the crystal? I saw Otto Frei has the right crystal, but they don't mention the diameter. I picked up a couple of Omega crystals that are around 29mm/30mm, hopefully one of them will fit.





This one could use a dial cleaning too...

 

I don't remember the size. I would order one from Jules Borel. That's where I got my last 2782 :
EA PX5000 CRYSTAL, YELLOW

 

These are ring crystals where it needs to be an exact fit.

 

2782-6, I bought two 29.6mm, one 29.95 and one 30.6. They were about $5 a crystal and they might come in handy in the future.

 

you want to get it with the matching ring as Mike says.
