Pocket watch movement identification

[ScrewDropper]

I was an avid user of the Ranfft database but, with the death of Dr. Ranfft that is now a lost treasure. The scraped DB is average at best and the owner doesn’t reply to emails requesting membership in order to help curate the content, oh well.

I have this pocket watch and the only clue I can see is that it was Swiss made. There is no serial number and I can’t see a maker’s stamp. I’ve not started disassembly yet, so there might be something dial side. If I find anything I’ll add it here.

it might be just hope but I’ve seen similar looking Omega movements but they usually have the bridge signed so I’m not holding out for that.

In the meantime, any ideas welcome!

Escapement and balance designs can be good indicators

Keyless works ID is the usual method if the movement is within a set time period

Size would help narrow down possibilities.

I have added some photos. I believe those measurements make it s14. There is a lip on the base plate and a dust cover, as can be seen in the photos, which is reminiscent of US watches. The winding is push in for time set which is the reverse of many US movements. There is a number on the dial side, 120, and that is all I can see. It appears to be a higher end movement, having 17 jewels and Guilloche engraving on both the front and back of the movement. Hope that helps

 

 

Some further details. Underneath the barrel bridge was the marque G.P.CIE where IE is underscored with a bar. There is also one less jewel than I thought. The dial side bearing for the center wheel is not jeweled and looks to have been at least one of the reasons for the watch not running. The center wheel staff is also badly scored and there’s signs of rust around the brass bearing (from the staff). Looks like I have my work cut out

Girard Perregaux

Yep, I think @Neverenoughwatches nailed it.  Girard Perregaux & Cie [...and company].  One of my favorite makers.  Constantin Girard and Marie Perregaux were a husband and wife team!  Because I work alongside my wife at my day job, and have for many years, I understand the attraction and admire them.

That was the conclusion I came to when I saw the marque. The thing is, what caliber? I’m going to need a centre wheel at least and I can’t find a match, although the fact it has been narrowed down to a GP is making life a lot easier

A worrhy piece of information and approach for combining work and marriage Karl. My mother used to tell me how to determine if you had found the right woman " wallpaper a room together before commitment and if you can manage to do it successfully in short time and without argument then she's the one " . Maybe i should have listened, when me and my  missus do it, we need to buy extra rolls, it takes us ages and then we dont talk for days afterwards .

Get those keyless parts laid out so we can all have a skeg.
