Wow, this fooled me real good. Pulled it from a good 40's 992B thinking it was the #082 "export".

Looked really good, just like porcelain until I started to wipe it clean and realized it was flat and not even single sunk. When I removed it from the movement......suprise....'swiss made', enamel on metal dial. A perfect fit though.
If I stuck this on a 2974B or a 1943 992B movement, I bet it would fool alot of people!
