No, the numbers aren't glued on, (not on a Gen anyway). Also, the stick marks between the bezel numbers are polished too much. The edges shouldn't be so rounded.
I'm wearing a Gen. 24 as I type this, and if this is the way a Gen comes back from Panerai, I won't be sending it in of service!
Then I have seen some real screw ups from Rolex Service in NY. That is the very reason I have always waited the extra couple of months and sent the Rolies to Switzerland.
The polishing is just too easy to screw up.
The case lugs are way too rounded and over polished as well. Perhaps the workers in Dal. are just sloppy or inexperienced.
Other than this, it is a good looking watch.
