this one on the 'Bay is a real hound...
"rare Tiffany dial Constellation circa 1960"
Tiffany added with sharpie
167.005 case back on a 168.010 case
At least the 564 matches the case and dial (but neither from 1960)
Medallion ground off - how thin must that case back be...?!!
Yours for $2180
Run far away....

So the best way to raise your watchs value is to add wordings Tiffany, turler, meister.... to the dial

 

As long as you have a steady hand and a fine tipped sharpie.
