Below is a "Heuer" that was sold by a dealer this year. I am not an expert on Heuer but the watch appears to have a laundry list of unusual attributes. I question whether any part of the watch is authentic. Starting with the dial, I am not well-versed enough to make a confident assessment. However, my untrained eye finds the seconds scale, sub-dials, and hour markers odd. Though not an issue on its own, the pristine condition in conjunction with the aforementioned potential oddities is noteworthy. Lastly, the absence of lume does not fit with the luminous hour/minute hands. So, it seems reasonable to assume that either the dial is wrong, or the hands, or both. Moving onto the case, there are a number of atypical features. Firstly, there are the large round pushers. Comparing these pushers to all other round-pusher references listed on OnTheDash with Valjoux 71 or 72, none are similar. As a side note, these pushers can also be found on certain examples of the highly suspicious "original" Longines Avigation BigEye chronographs that have surfaced. Secondly, the case-back markings do not fit with original examples. Comparable examples have perlage, an "Ed. Heuer & Co Swiss" marking, and either "Stainless *Steel*" or "Stainless Steel".

Firstly, Heuers with the Valjoux 72 (pre-1960), usually have copper-toned wheels. The example in question has silver-toned wheels. Secondly, original Heuer Valjoux 72 movements usually have a distinctively-shaped "chronograph" bridge. The example in question has a generically-shaped bridge. The bridge is also missing the usual 6-digit number. Furthermore, the "Heuer" marking on the bridge is also missing its usual copper tone. Thirdly, the balance cock with mobile stud carrier is not typical. I also find it noteworthy that the movement of the example in question has severe where underneath the balance wheel, and an incorrect minute recording jumper spring.

Unfortunately, the given example is not the only one I have seen (three thus far). I look forward to any comments.
