...open up your Veglia and close it back again...

Might have to try this too! Mine reads half the correct rpms.

Shame there's not a way to pop the bezel off, but I guess it's crimped on, so cutting the can in half is a good trick!

And you are confident Relay#2 is the best it can be?

If you are sure you need to disassemble it, the bezel can be removed. I machined a pocket for the bezel to fit into, but others have used a big hose clamp. The trick is to keep the bezel from deforming as you carefully go around the crimp with a tool such as a tack puller, or a specially ground screwdriver. Just keep picking up the edge slowly as you go around it. Putting it back on is just the opposite. I used a peen punch with a polished radius to slowly tap it back in and down.

I have a big lathe and mill, so hopefully I can improvise some tooling to ease the bezel open and then push it back after. I saw someone use a bearing in the toolpost to roll the bezel back into place...

Are new uncrimped bezels available anywhere?

Well my relays are Omron's and the terminals are all spotless...

It'll be duck soup, then. Just make a cavity with a light push fit on the diameter of the bezel. Depth will be the same as the bezel.

Yes, one of the speedometer repair shops *has* bezels, but at an exorbitant price.. he obviously wants to get paid to work on yours. <shrug>

Duck soup? Ha! I like that. Not heard that phrase on this side of the pond. We might say "Lemon Squeezy" or "A piece of pi$$"

If it rattles, that means the counterweight has come loose.  And just won't show RPMs.  I took mine apart with a hose clamp and filed down paint can opener.  It was tougher getting it back on after I got it off. I just epoxied the weight back on.

If it is showing consistent but wrong readings and doesn't rattle, I'd look at electronics causes as mentioned above.
