Pultra oil sight glasses

I have to turn up two new brass sight glasses for the Pultra 17/70 but unsure what to use for the glass part anyone got any suggestions it needs to be very thin.

Sorry to drag up old thread but I am rebuilding my Pultra (Repainting really as it's great condition) and managed to pop the lenses out of sight glass. I had no idea watch crystals went down so small, so thanks for the tip off.
