I landed my first Sangamo Special - 21J True Bridge
I'd appreciate any feedback on the correctness of this one. In keeping with our mission for making these things right. Hands/dial/case... The case is a 20yr philly. Dial is No. 114, hands are more typical Bunn. Interesting that I found a 1927 circular showing this No. 114 dial made and marketed for the Bunn and Sangamo Special.

This model 9, SN: 2790456 checks in as a 1916 watch and I don't know how far back the No. 114 dial can go. Although and argument could be made that it might be a correct replacement dial if an owner had issues with the original.

After two years, I think I have finally found a focus.

The DG&S I restored last month was my first "true bridge"... later I read some stuff posted recently on the Hamilton true bridge models... and then this Sangamo came within reach.

Paul, I am no expert, but! I believe the case SHOULD be a Sangamo marked model and the hands different. That being said, it is a 21 jewel rather than a 23 jewel so I could be wrong. My wife sometimes points that wrong part out to me Wink

Mike,

Hands and case are my specific question. The Plum RR hands are pretty common with this dial... but I'm not sure if there is an expectation that there be kyte hands on this model.

And regarding the case, the Illinois data base is usually pretty good at stating if a watch is factory cased or not... and the ad from 1917 I was able to find looks like it is for a loose movement.

Everything looks OK to me, the "really cool Jewels" are ALL Ruby or Sapphire, the minute hand may have lost about 2mm of the pointy end . . . Lets see it after you clean it.

This true bridge reverse screwed on cap jeweled type is rare for that very description, but I do think that a Jeweler could buy it as a movement only.

Illinois started fitting 14K gold cases and then specially hinged cases to S.S. in the 20's sorta culminating with the 17s version which MUST be specially cased.

Dave,

Is this motor barrel going to come apart like the Waltham with the two piece threaded arbor?

Thanks, pault

Paul,

Nice find, a very important item.
Rest assured your 21-Jewel True Bridge Model 9 Sangamo Special (total production 2,420) fronts the correct plum hands and one of the appropriate straight-line signature dials for movement number 2790456 the details of which will be added to the 1915 section of our "ILLINOIS SANGAMO SPECIAL MODEL 9 DATABASE" information as follows...

2790456_______21_________Gold________No__________True______*Screws up, 11/06/2014

Look through the details there for more information.

The case type on your movement is appropriate for that 1915 time-frame as well, the Model 9 movements like yours were predominately cased and timed by the retail selling jeweler in a case selected from those available at point of sale.

We find specifically styled Sangamo Special Cases a bit later with Model 10 introduction during 1917 production as shown in our "Sangamo Specials, Marked Factory Wadsworth Cases Database" information. There also, during 1920 with number 3693001 you will also see the beginning of 17-size movements, which as David pointed out then continue all the way through the end of Sangamo Special production.

Congratulations on your most recent acquisition!

Lindell

I picked it up for $404 delivered if you want to add that to the data.

Paul yours is a conventional "going" barrel. The later design Illinois motor barrel is discussed at length with pictures at;

Thanks Dave, I'm real familiar with that style.

Now I'm on the lookout for a bridge model with the jeweled motor barrel...

Anyone sitting on one?

Its been said time and time again that the Sangamo grade watches were the cornerstone of the industry and I personally believe that !!
