Vintage ORIS crystal

[SPIGGOTT]

Hi,

 

just finished servicing a Vintage Oris with a Cal 291 movement.

Removed crystal to clean case and replace.  When removed it does not look like anything I have seen before.

 

it has no real edges and is flexible.  Can prod it with your finger and is is squashy.

 

i have attached some pictures.  How or even is it possible to replace this....

 

thanks

The info in these docs is well worth reading if you haven’t seen it before
