Crystal not fitted straight on restored SM120

I got back an old Seamaster 120 from a restoration a couple of days ago. All in all super satisfied, as the watch is looking (relatively) great and running after sitting idle, broken and in very bad shape for over two decades.



I did notice though that the crystal is not fitted entirely straight. As you can see in the photo, on the left side the straight wall on the sides of the crystal sticks above the bezel a little over 1mm (can easily run a fingernail along that side). While on left side, only the domed part sticks above the bezel.



Is this a big deal or an easy fix for the watchmaker?

That's really not great work at all.... I'd be taking it somewhere else to have the quality of the rest of the 'oil change' assessed.
