Once you get everything clean you may want to try Eastman 910. It is the original cyanoacrylate adhesive. Eastman developed it specifically for lens manufacturing. It differs from super glue in clearness and quicker drying time. Practice with some scrap material first. We were using it in the early 60's in the manufacturing of cockpit instruments for ILS and VOR.

Here's something I haven't tried, but might work very well (but will
require great care).
1. Use a piece of very sticky tape, fold in the middle with the ends
bent out (like _!_) and attache to the middle of the glass. This forms a
handle to gently pull on the glass.
2. With the glass vertical (normal viewing position) put very fine bead
of super glue (or other runny glue) along the BOTTOM edge of the glass
where it meets the bezel. and let it run down . CAREFUL to not use too
much to where it runs inside the meter or down the bezel. A wetted
toothpick or similar might help.
3. After the glue sets thoroughly, turn the rig upside down and repeat
on the top edge. You could also do the same thing with the rig set on
it's sides. The idea is to not let the glue run inside the movement and
mess it up.

(1) it's tricky to get the cement in the right place without getting it also in the wrong place.(2) You need some gimmick to pull the glass back up snug against the casing while the cement sets.
