Bila WirriganwaltersRequest for Rockford Serial Numbers from 1-543,000
Great John thank you, would you happen to have a picture you can uploaded?
April 05, 2020, 20:38
John WillisHi Bila. I can take a pic but am having trouble
"compressing" them. I will contact Dr. Debbie and see if she can help out. John

Bila WirriganwaltersJust a tidbit of info on some of these earlier Rockford's, in the first 15,000 produced on the numbers we have at present there are approximately 16 changes backwards and forwards between the Model 1 & 2's. Also within those first 15,000 there are more then 75 Grade changes (of the available Grades of the time), so as you see it will take a lot of numbers to find out what, when and how many of these differences there are.
So I implore anyone with numbers or examples laying around could you please contact me or upload photos and details of what you have (if unsure photos speak a thousand words, this info should include if possible; serial, model type, if stem & lever or key-wind & set and jewel count) if you have not already done so, thanks to all for their contributions to date and thanks for any that are forthcoming

John WillisHi Bila> Re: #156367 Hopefully the enclosed picture will show this movement (it is a picture I have on file) . Just got a new computor operating and hopefully got the "compressing" thing figured out. Maiden try!. If it is succeccful and you would like to see other pics of it let me know.

John Willisanother pic.
June 22, 2020, 11:47
John WillisBila. I do not have any pics of under the dial. If important I can do that, John
June 22, 2020, 18:41
Bila WirriganwaltersAppears to be a 9 Jewel Model 2 stem win & lever set John, can you confirmed that it only has the 2 jewels on the back plate, as the 2 pivot holes under the balance wheel are hard to see?
June 22, 2020, 21:38
John WillisHoles under balance wheel are jewelled. I had thought from my other pics that they were not jewelled but it was bothering me a bit so I dug out the watch to see and they are definatly jewelled holes in the back plate. The front I am not sure. As I have it out would you like me to check under the dial. John
June 23, 2020, 01:43
Bila WirriganwaltersPlease if you could John that would be great

June 23, 2020, 10:31
John WillisHi Bila. Looked at front plate and those two holes are not jewelled. I took pics but for some unknown reason cannot download to computor.If/when I get that sorted I will post. John
June 23, 2020, 21:19
Bila WirriganwaltersThat would be great if you can get it sorted John, a clear picture of the dial plate side would be good, as it is odd to be a 13 jewel.
June 23, 2020, 22:16
Bila WirriganwaltersAlso John is it possible to see a better view of those to hole jewels on the back plate to see how they are fitted, as the hole sizes look smaller then they should be for a factory job?
June 24, 2020, 11:34
John WillisI will do that when I get my downloading problem. Have a good day, John

Bila WirriganwaltersExcellent John Thank You, this is what Rockford called "Plain Jeweling" in their Grades. Also this one has created another different data point in the serial database.
June 24, 2020, 20:37
John WillisHi Bila: Glad to be of some assistance, however small. Appreciate you efforts for all you do. John

Bila WirriganwaltersJust bringing this up to keep it in everyone's thoughts as we are still chasing serial numbers

August 18, 2020, 17:54
Gary E. CochranBila this is the 7502 I found in a drawer I hadn't been in for a while...11 Jewel marked on the M/S barrel cover...

Bila WirriganwaltersExcellent Gary, photos are fine and another serial we didn't have, cheers

Douglas D. WeaverBila - I have a couple of early Rockfords. The first is #15323. You may already have this one. I posted a question about it a couple of years ago.
It has:
gilt plates
11 jewels
It is KW/KS - but also has a stem wind conversion for a hunting case that doesn't work.
2 case screws

August 21, 2020, 15:50
Douglas D. WeaverNext is #90291
gilt plates
7 jewels
KW/KS
1 case screw
August 22, 2020, 02:57
Bila WirriganwaltersThank you Douglas, these 2 cleared up a couple of errors, the 7 jewel had erroneously been reported from another source as 9 jewel and the other was originally seen in a key-wind case but yet fell in a run of Mode 2 transitional's, so info very much appreciated

Bila WirriganwaltersFor all who are interested in these earlier Rockford production runs just a tid-bit of an update regarding the chopping and changing of movement variants.
I have just briefly gone through the first 40,000 serial numbers (based on the small selection we have at present) and have found that the Models as designated (based on the model 1 & 2's and the like) changed backward and forwards 55 times in this first 40,000 numbers and the variances within those model changes show 160 different Types/Grades (these different types refer to jeweling and the like but not including variances in font and other attributes). These numbers could change to a degree as we get more added to the database.
So as you see to work out exactly what was produced by the Rockford Watch Factory a lot more numbers will be needed. So if you have any please put them forward for this important research. Also for those that have already, your participation is very much appreciated
