There's just a few things wrong with that Monza.

Comparing it to my *real* Monza 150.501:

1) It isn't! It's a cal.12 (11?) which would make it a 110.501, so at least the case back is incorrect. Also, my caseback has a serial number below the model and above "SWISS MADE"

2) Painted case? Yuk. And the nice sharp case edges have been polished off before painting. Hardly "near mint"

3) The pushers look suspiciously too long, and not fluted.

4) Not sure about the crown, but it certainly looks too thick. Did the "economy" or other cal.11/12 Monza's have logo crowns?

I can see why this guy has a "history" with this group.
