Thank you, I did not even notice the marking under the balance, It is a 2460 ETA. I normally only buy pocket watches so wrist watch movements are more newer for me.
I had done some more research last night and compared to others and I had shortlisted it down to an ETA around those models.
I have this early automatic mens wristwatch movement from what looks to be around 1950’s era?
It looks like very nice quality and does run, does anyone know the maker and model? And who may have retailed this one?
Hi Bila, Yes there is limit info around on the Columbus pieces. I don’t have the Columbus book either so hoping someone can let me know grade, how many grades there were above this and possibly how many made. Yes it is a transitional piece. I have not had the dial off but may also have no...
Yes this is the one I mentioned a month or two ago. Got some photos finally.
Yes someone did get at the two settings, seems they thought they were getting in the road of the balance. Very silly but still a great piece. Adjusted marking is larger than normal as well.
Nice piece Dave.
The AM Watch Co Waltham Mass text is very uncommon the way it is spaced and font style. also the fancy flourish around the text is very uncommon as well. I have only ever seen one or two like this.
Thanks for posting the watch up Dave. I have a couple nearby in a small run inside that 100 made and was keen to see if there were others and to compare them. When I have some good photos I will post them up.
Thanks Bila, Yes it does seem clear that Rockford were quite flexible on standards for how (various text formats) and when they finished some serial numbers. I was looking through many images today of the early 15 Ruby Jewels pieces and it is very interesting.
Very nice pieces indeed Fred, pretty much the best of the best 16s from Illinois in that 25j. Do you own both of these now? Haha yes and both shown on the back of the Illinois Meggars book :)
Sensational fine damaskeening on them!
The SN 58601 photographed has to be the first made Nickel 15 Ruby Jewel from Rockford wouldn’t it? The earliest Nickel SN’s seem to be no early than this one, various numbers through 586xx and 587xx.
Very interesting for the plate text very a lot through these two short runs. Adjusted in...
I agree with Dr Jon. Ekegren. The SN is too early to be a Patek when this model style. If it was Patek the movement with a serial that early it would be an early gilt piece and most likely early cylinder Swiss bar style.
I have referred to this site many times as a very good visual resource for many of the models and grades from IWC. SN 554 is shown on here, which is the new lowest serial number watch known.

Hi Bila, Yes it has been a while but going well mate. I hope you and the family are also going very well.
The piece is pure Keywind Keyset And is marked adjusted just near the serial number. No Abbott’s on this one. Interestingly it does have a peculiar screw on it which I am unsure of...
