I believe this is actually a 17 jewel Precision V3 Madretsch movement circa 1910 if i'm reading Thojil's post over on the NAWCC site correctly. Vendor indicates that it runs well but he had a problem getting the stem to set in correctly. Jack has pointed out that this being a positive set stem & needs to be in a case to work properly. And there was a suggestion that the wheels, the setting for the center wheel jewel and possibly the dial are all solid gold but i cant confirm that until i actually receive the movement from the vendor.
Yes, this is what I belief to be an early V3. The design is different from the later V3 in a few areas, one of them being that this early version does not have the positive set stem as opposed to the later V1, V2, V3, and also V4 and V5. So if the stem doesn't fit there is something else wrong.
Also the click & click spring design is different and 'chronometer balance' is not mentioned. Visually I have not been able to spot any difference on the balance versus the later chronometer balance signed movements. But then I'm by no means a specialist in this area, so it may be a difference in the level of finishing not visible to the untrained eye.
The solid gold wheels and other parts are solid gold according to Gruen's own description in the 1916 Blue Book. I have confirmed it for at least the center wheel on one of my movements which has a few broken teeth.
You could be lucky with the dial, but these were not by definition solid gold.
