David,

I've never tried to remove the cover, mainly because there's a small spring to deal with.

I can imagine the spring shooting across the room, never to be seen again. >.<

Sometimes the pin in the hinge can be tapped through the opening, but they're often pounded flat or crimped somehow, to make the task more difficult than it would appear.

Probably quite easy for someone who works with watches and has the proper tools.

Timepieces are another lucrative area, where many engravers fear to tread.

BTW - The $25 was charged to a trophy shop client, who will probably resell the engraving for $50.
