Quick aside --- With the similarities in construction, I have wondered if Gruen licensed the Pioneer patent for all of its threaded import cases from the period. It is possible, since the patent was filed in 1939, that the technology had been available.

I've always been under the impression that the Pioneer patent was more to do with the way the crystal went into the case, than the other aspects. The Borgel/Taubert patents seem more close to the Gruen Watches. But I do not think that Tauberts supplied to Gruen.... I think it is somewhat too coincidental that Gruen went to the 6 point case back about the time Tauberts may have sued come companies for patent infringement. I think this was also the case for Pioneer WCCo and their polygonal case backs.

T Haven't found a clearer image...

Well... the irony is that the ad you show is a photograph I took of the print proofs for a number of ads that Charlie Cleeves had at a show in 2012, or so. I went back to the original image.... still not much better

All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
