Identify Elgin movement


Recommended Posts

Hi everyone. 

I picked up a nice Elgin wristwatch from the bay for around $100 Australian dollars. 

It appears to have a broken Balance staff and due for a service. 

There are no markings under the balance cock, how do I go about finding the movement ID to get a new staff? 

Is it worthwhile trying to get it running? It looks a tad small on my wrist but I have a few vintage omegas in similar style. I'm not sure if it was originally a wristwatch or if it's a Hodge podge. 

I might send the case to Canada to get a up on the rolled gold. It's very thick gold I might add. 

I can measure the movement later. 

Cheers Alex.

For the most part for Elgin if it has a serial number you go the pocketwatch database and look it up. Then if you're lucky on the parts tab ill Bill the finder parts. Unfortunately for balance staffs it isn't always that simple as there may be variations. Usually any time you restaffed any American pocket watch you always want to measure the before and after to make sure the replacement staff actually is the proper replacement staff that way you would avoid unpleasant surprises.

If you look through the parts go to the staff section you will get the image that I have below. You'll notice I highlighted something the staff conceivably has variations. Elgin unlike other watch companies for the staffs would have a part number but the part number would action referred to a whole bunch of staffs with variations. Typically it's just pivots size variation but other times other dimensions Very. Then when you order a staff online it may be a generic replacement that may not actually exactly fit the staff you have.

I'm attaching a second image it looks like I was correct there are some variations for pivots size. It would be really nice if one ear pivots still existed. But as a guess is this is a seven jewel watch it's probably the largest size which works out fine any staff would work then hopefully. Sometimes the generic replacement staffs are deliberately made over size as it's easier to reduce the dimensions than it is to add on to the staff.

Then one more image there's a reference to single and double roller normally that would be physically different staffs but in the case of this staff will work for either or so I variation in size you have will be the pivots.

I have found by serial number that is a 462 movement. I am now sourcing some parts.
I got the train bridge running well.
My balance is broken, winding wheel missing a tooth and the click is worn down.

Very interesting crown design. The crown setting lever is in the case/crown.
The movement drops out without having to release a setting lever screw. Very peculiar and clever.

Typically traditionally with American pocket watches and some Of the wristwatches this is what you have.

Also if you look carefully you'll notice that when the movement is out of the case it's now in setting. That's because the crown and stem in the case determined where the crown and stem are by the sleeve in the case.  If the movement is out it automatically goes in To the winding position. This then presents a problem if you're trying to run the watch as your now driving the entire setting mechanism. Watch manufacturers recognize the problem and Oftentimes provided a way to put the watch basically into a diagnostic mode which puts the watch back into running out of the case. Fortunately they all had slightly different methods. So I almost need to see the parts under the dial to tell you how to do it.

    • The part was how it fell out of the movement - the train wheel bridge wasn’t screwed in.    I’ll probably dismantle the part, if I can, to work it out.    The train of wheels ran fine - it was only once the keyless works were installed I noticed the problem. 
    • Hello, I am about 5 months into watchmaking and I love it!   The attention to precise detail is what really attracts me to it. (and the tools!) I am working on a 16 jewel 43mm pocket watch movement.   There are no markings besides a serial number (122248) .  The balance staff needs replacement. The roller side pivot broke off.  I successfully removed the hairspring using Bergeon 5430's.  I successfully removed the roller using Bergeon 2810.   Did i mention I love the tools?! I removed the staff from the balance wheel using a vintage K&D staff removal tool  with my Bergeon 15285 (that's the one that comes with a micrometer adjustment so it can be used as a jewel press as well as a traditional staking tool...it's sooooo cool...sorry..  can you tell i love the tools?) No more digressing..  I measured the damaged staff in all the relevant areas but I have to estimate on some because one of the pivots is missing. A = Full length  A= 4.80mm  (that's without the one pivot...if you assume that the missing pivot is the same length as the other pivot (I'm sure it's not)  then A = 5.12 mm...(can I assume 5.00mm here?) F=  Hair spring collet seat  F=  .89mm   (safe to assume .90 here? .. I am sure that my measurement's would at least contain  .01 mm error ?) G = balance wheel seat  G = 1.23 mm  (1.20mm?) H  =  roller staff  H =  .59mm  (.60 mm?) B  = bottom of the wheel to roller pivot   B  = 2.97mm  (3.00 mm?)     here I am estimating  again because this pivot is missing. So my friends, and I thank you profusely,  can you point me in the right direction as to how to proceed? Do i buy individual staffs?  or an assortment?   Since I don't know exactly the name of the manufacturer, will that be a fatal hindrance?   Tbh, I'm not even sure what country of origin this movement is. Thank you!    
    • Thats why i asked that question earlier, what happens if lubrication is placed directly on top of epilame ?  As opposed to walled within its non epilamed area . I'm not saying its right, i have no idea , just asking questions. 
    • thinking of where epilam should be removed did you know there was a patent that covers this? At least for the escapement I'm attaching it. GB1057607A-1 epilame.pdf
    • Back home...printing now.  Will report results
