Lord Elgin Durabalance

[LittleWatchShop]

Found this in my stuff.  Very interesting movement.  Gonna put it toward the front of the queue for servicing.

I will plan to document the process...start to finish and then post (cross your fingers).

Sorry for the lousy picture...better ones will follow when I go to work on it.

Here is an article about the Durabalance

I never got to this...still in my TBD box with a hundred other things.

I don't see the movement number mentioned anywhere?

No you don't.  The original post was a half year into my journey and at that time did not pay too much attention to such things.  Also, I did not know what @JohnR725wants to see.  Nowadays, when I post, I have you as a little angel sitting on my shoulder whispering the necessaries elements of a good post!

I am remote right now.  If I remember when I get home, I will find the watch and post the number.

the reason I asked about the movement number is Elgin had a blue notebook which you probably have lurking around the house someplace. In the notebook they have service information for the automatic watch and I think they have something on the balance wheel in their.

then yes the balance wheel is really interesting. something to confuse the watchmaker was never seen such a thing.

I just found one of these myself!  With the 760 movement and Durabalance and all!  This movement is wild!  I've never worked on a free-sprung balance before.  And I was advised not to dismantle the clutch system (which requires special tools and skill).  Apparently it consists of two clutches in one, and works like a sprag clutch.
