Hi folks,

I need some advice and info on one of my watches, A GP from 56 or 57 if the numbers are correct.  Originally Gold Plated but the vast majority of the plating is gone and there is a fair bit of base metal showing around the edges.  The movement is solid and keeps time with the best of them, but the face is white and is absolutely immaculate with barely a mark on it.  Anyhoo, apart from the number on the case and the serial number on the movement, I've been unable to find a calibre marking on it either.  I could be well wide of the mark here, but the hour markers appear to have been machined into the dial, anyone seen this before?I have no other way of identifying this.  Is anyone able to help?

It is an absolutely beautiful watch, but the plating is really annoying me and I'd like to sell it, but I need to know what it is first.

If anyone can help I'd be extremely grateful.

Hiya Frankie. Check under the balance assembly mate, quite often therexwill be a manufacturer name and calibre. If not then the keyworks needs a looksee at.

Whip it out mate ( the balance assembly that is ) look for manufacturing logos, shields, badges etc. The bestfit books and downloads will show you most of them.

I worked on something very similar to this several years ago. It was a Girard Perregaux Cal 22. An automatic version of the Cal 20.

I noticed something about your movement, it doesn't have a sweep second hand, seconds pinion and free wheel. I'm not sure if it's a factory option or an after market modification.

Thanks very much for this, folks.  I've been away for a while, so apologies for not responding sooner.

This is far more than I hade before and I'll be following up as best I can.

I don't have the cohonnes yet to whip it out, I'm afraid, its a confidence thing and it'll come, just not on a movement like this one.  I really like the watch and although I said I wanted to sell it, I think id rather find a case for it.  I've a balance to swap on a cimier 10 jewel, so I'll get that out the way first.

The watch is exactly as I found it around 15 years or so ago, so I can't comment on the absence of the parts discussed earlier.

I like the simplicity of it in that it tells you the time and nothing else, but does it in a very pretty way.

So, I'm off to find out what I can from the above references and see how it goes.  I may take some pictures of the cimier balance swap, if I can stop my hands form shaking in trepidation!

Cheers

GP 18. 

Anvil was real close, gp20 is sweep second though.

And a peseux 330 , gp modified it,  eliminated the seconds hand.

    • Thanks for this post MikePilk, I just came across a similar problem with an Omega 1022.  The problem I had was the seconds pinion spring was bent out of shape and did not even engage with the wheel properly, so the seconds hand was not moving at all. (no power loss though :) I removed the automatic module so I could access the spring and work on it. Once I bent it back close to the right shape, I experienced the same problem you reported about power loss.  Many tweaks later, and the seconds hand is moving properly again, with amplitude back to good numbers again. Cheers
    • After cleaning up the pivots, I made bushes on the lathe. At this point I've pressed in 6 bushes (3 sets) and the wheels turn smooth. What I can also tell you, is that I'm not looking forward to final assembly. Getting the pivots aligned seems to get exponentially more difficult with each wheel that is added.
    • Islands are interesting places to live depending upon their size and other factors. This is a bigger island and it has a bridge to get there at least on one end. It's also big enough that you don't have to go someplace else to get things typically. It can be a problem if you get a job in Seattle though. Yes I've known of people who commuted from the island to Seattle for a job and I don't quite remember how many hours it took but it took a long time. So basically islands are nice if you don't have to leave very often.
    • Thanks @JohnR725! Everything you say makes a lot of sense and is encouraging to read.
    • isn't it nice to have a decent case open or when the case doesn't want to be opened? In the case of a Rolex watch that supposed to pass specific water resistant testing you probably do need to tighten the back down. But they shouldn't be tightened so much that they risk stripping the threads out. Then the other problem that comes up is the gaskets can start to disintegrate and then getting the back off can be quite a challenge unless you have a really good tool and perhaps some penetrating oil to loosen things up. Yes really nice case marking. When I was in school we were taught to mark the cases and  the American watch and clockmakers Institute even had a? So if you joined at one time they would give you an identification number. They were explaining or giving an example of if the watches ever found in you have a unique number they can perhaps figure out the history of the watch or identify the body it's attached to for instance not that that probably comes up that often. So you got a unique number and even made a special metal stamp that you can purchase. It wasn't a super big aggressive stamp but still it left a mark in the back of the case. Then I heard from people at work on Rolex watches they were using a felt pen indelible but later on they decided that was bad because apparently the ink could release  chemicals although it seems like once it's dry that shouldn't be an issue. Then of course today was nice is you can keep computer records sealed have to mark anything at all I personally find it's best to leave no reference behind that you were even there. Especially when you have a beautiful watch that has no markings at all and now it has your scribbling all over it not good typically if there is a typical and watch repair?  a lot of minor repairs you don't need to do a complete servicing. But beyond a certain point you're going to have to take apart a lot of stuff you're going to disrupt the lubrication even if it looks perfect right now and yes you might as well just go ahead the service the whole thing. also in a watch like this where a lot of things seem to be going on the complete service would be better then you'll know exactly where you stand versus dealing with unknown mysteries for prior repair.
