The watch (referenced below) is claimed to be an original with all original parts (except the band). Yes, I see that the movement is Bovet (which is actually why I am interested in the watch), and I am puzzled as to why Heuer would have another company buy a Landeron 47 ebauche, assemble it, stamp that company's name on it, and then put a Heuer dial on it?! Here is the Ranfft profile on the movement http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&Landeron_47 from which it appears feasible that this could be a WWII period watch. Finally, I am cautious because the seller is from the Ukraine (which although it is a source of fakes, it is also a plausible location for finding these sorts of watches).

The seller gave the following reply to my request for info:
All parts on this Watch is original. But
the dial was restored. The watch and chronograph function is in a working good.
The watch checked, adjusted by master in 2008.
I purchased these watch for the veteran of war.

I'm interested in hearing from Heuer (and related) experts, or people with important relevant information, only. I can do my own guess work.
