Hi all of you out there....
I need help to identify a Ladys watch movement.

It's a Girard Perregaux, with the following engraving on the movement:

Girard-Perregaux
5829471
17 Jewels Seventeen
Swiss
Unadjusted

On the balance bridge, the letters GXM are engraved (Girard Peregaux manufacturer code).

On the inner side of the back cover the following is engraved:

GP
14K GOLD
A logo which contains a D letter with a smaller B letter in it.
2068
1707


I hope all the above will help you help me :-!

Thanks in advance, Saul.

Before GP started to develop their own movements they used Adolf Schild and ETA movements. You can try searching here. If you use the advanced search you will be able to get a match if not a perfect match.

Thanks very much Emmanuel,

I did go to that site but couldn't find a close match.
I revisited the site with emphasis on ETA and AS, still no good match.
I need to get the keyless cover for that one but before I go to Jules Borel site, I need to know the caliber.

Thanks,

Saul.

You can send an E-mail to Dr. Ranfft with a picture of the movement. He would more then likely be able to identify it for you.

They also used quite a few FEF movements.

I didn't know that. Thanks for the information Marrick.
I didn't know really, but I sometimes cheat in Ranfft's pink pages. If you enter, for example, 'girard' in the search box, a list of movements that Roland has annotated as Girard-Perregaux comes up.

e.g: for FEF 6621:

Example, year: signature; shock device
ca. 1980: 504-424, Girard-Perregaux, Swiss, 17 Jewels; Kif-Ultraflex
(Girard-Perregaux 504, FEF 6631)

and quite a few FEFs that were similar (but not identical) to the movement in question came up.:)

Yet another example showing your searching skills are amazing. :-! Good idea.

Hi Saul,

the number 5829471 consists of a calibre number (58), a version number (29) and
a batch number (471).. So you should order the settig lever spring for a GP 58.29,

No need to search in the movement archive - it is still missing.

Well done Roland Ranfft,

I have just received an official reply from GP as follows:

It is a movement Cal 58.29 produce in 1962.

Your movement could be repaired, but only in our workshop in Switzerland.

I remain at your disposal,

Sincères salutations, Best regards

Logistic Manager - Customer Service Girard-Perregaux & JEANRICHARD

You don't really want to know how much they want for the repair, unscrewing 2 screws and assembly of the new tirette.

I will try look for one by myself. Jules Borel and Cousins UK don't have it.

Still waiting for a reply from a German supply house (Ernst Westphal).

Anyone got an idea?

Thanks, Saul.

I assume this numbering scheme holds true for all of GP's movements?

Hi Saul,

the base movement is surely a Peseux 340, but this has a different setting
mechanism. But I guess, if you replace both, setting lever and -spring, you'll
be successful.

The best chance for a Peseux 340 is a Junghans with J70. Probably even
most Peseux 340 were sold as Junghans J70. Just browse the German
ebay.de now and then.

Regards, Roland Ranfft

Just found the original GP set lever jumper at Ernst Westphal in Germany.
It is the last one in their stock and it doesn't come cheap. I hope the originality and functionality will worth it.

The movement on Ebay is sold As Is "for parts or restoration". The dial side is not shown so I can't be sure that what I need is there.

Problem solved and thanks very much to you all for your participation.


Regards,

Saul.

Hi emmanuelgoldstein,

Yes, but there are some exceptions forcing to consult movement registers.

In most cases both, the calibre number and the version number have two
digits. But sometimes the version number has just one. And the first quartz
calibre came as GP 351, 352 and 354, but without noticable differences.

If I remember correctly, they had different Motorola chips.

Hi Eeeb,

Zeno assembled some models for GP in the eraaly 70s, and as Zeno dealer I got
some 25 samples from old stock, which were made between 1970 and 1973.
Among them were 351, 352, and 354, and all had the Motorola SC 10018F in
the early metal/ceramic case.

The number you cite is indeed the chip number. The number to which I was referring was the second one. It is a number that comes from manufacturing and, I believe, corresponds to the mask ID.

I do not have sufficient numbers of examples to say with a whole lot of assurance, but I had assumed the GP models incremented when Motorola issued a new model to fix whatever problems were in the previous mask.

The first chip I ever worked with Motorola on was the MC68000 and this was how they did it then, about 10 years after these GP chips (which I assume were custom to GP)... (Now if I could only find my first 68000 sample chip. It was serial numbered with 404 and I was told the first 400 were only for internal use. Lots of bugs but I bet I could sell in eBay for enough to buy a decent vintage GP :-d).
