====\It's Ed Koehn. When hthis was made Koehn was using H. R. Ekegren on special watches. This one is very fine but not quite Ekegren level.
Here is Koehn signed example.
Koehn used the Ekegren on the higher quality movements. At the time Ekegren would have been more recognizable for a name of quality. As to it being not good enough for an Ekegren label, I would think the eight adjustments could put it in that quality. I also believe I have seen this style of movement before but I need to look through my notes. I will need to see if this actually the same watch. But my vote is Koehn that is a PL but would have had the Ekegren name if it was not PL.====\
ok, so your opinion is that Koehn who owned Ekegren at the time, only used the "Koehn" signature on "Speical watches"? Like a grade or a model?
Dr. Jon,I wrote that Koehn used the Ekegren name on special watches.
All of these I have seen are very high quality, but not every high grade grade Koehn was labeled Ekegren. All Koehn watches are high grade in my experience but they made at least three grades, adjusted, 8 adjustments and I speculate extra or observatory grade. I was not referring to this measure of quality. I was referring to its degree of being special.
The Koehn Ekegrens are unusual, like a repeater or a more complicated watch. I posted an example in the lovely ladies section where I think the special aspects were doing 8 adjustments on a very small watch and putting it into a very special gold and platinum case.
Another example is a watch I saw at a very high end auction. The house did not note anything unusual about the watch and but after some looking I noticed that all of its jewels are blue sapphires. This is the sort of special thing that Koehn sold under the Ekegren label.
I have never seen one but I suspect that a an observatory chronometer regulated by Ekegren would have been labeled an Ekegren by Koehn; and I would love to see on even if it proved me wrong. I know both Koehn and Ekegren submitted competing entries in the Geneva trials but I have yet to see one of these.
Neither Koehn or Ekegren is now available to explain the rationale for the designation, so my speculation is just that, based on very interested observation.
I have a couple more that I may add:I don't think I can shed much light on how Koehn-Ekegrens differed from Koehn-Koehns, but the 11 examples in my collection might be helpful in identifying differences.

Thanks for the answer.It is by Ed Koehn. See Illustration of Koehn watches in Shugart.
Koehn serial numbers are loosey goosey but 80,000 is about 1900 and 86000 about 1920.
The flying barrel model was often private labeled.
