Unfortunately not, and I think you will never find one (never seen them sold as spare parts).
I usually avoid spare cases without the glass because usually they don't have the tension ring installed !!

Be careful as there are two different types of spacers (tension ring) fitted on the 11630: the primer goes INSIDE the gasket while the latter one goes BELOW the gasket.

I suggest to find a good artisan or a skilled watchmaker, it can be redone with anodised aluminium and lathe, but will not be cheap and, above all, you need the old one (even if damaged) to be copied.
Best.
