Cylindre 8 Rubis Identification and advice for repair

I inherited my grand-father's Vacheron pocket watch and on the day I open the box, it falls on the wood floor and the crystal shatters. Not even a day in my hands and it is broken. I can't believe my luck. Otherwise, it runs very well.
First I would like to know more about the watch.
The inscriptions are:
Stamped: AE, 18K, 31256,
Hand engraved: Nro 4.902 and N 5901All these in the back of the back cover of the case.
On the back cover of the machine, I find:
Stamped: 37256 Hand engraved g 28 1/2 signature. 54574 and 14189.
Pictures attached.
All help to find a cristal replacement are appreciated.
