Hi All,

I had some free time to work on a Pocket Watch I picked up a while ago. It wasn't running but it looked nice and appeared to be intact so I took a gamble.

It came in a tidy Dennison Star case and the movement says cal. 529 although I could not find much information about it. I think it is a Cortebert but Im not an expert. 

Disassembly was straightforward and everything appeared intact (apart from a missing adjustment screw on the balance). Nothing seemed worn or damaged and a couple of runs through the watch cleaner to clear the congealed gunk and it came out nice and clean.

Now I have this thing up and running Im not actually sure what Im going to do with it, Im not much of a waistcoat guy!

Not terribly dirty but a lot of gunk on the pivots.

And finally all clean and running!!

 Keeper or not,  just running isn't all, should see ON TIMEGRAPHER how HEALTHY its running in various positions, specially that a balance screw is missing.

Your right its a cortebert, you know Russian Malnija copied cortebert

Malnija 3602.

I am not sure if balance screws off malnija fit your watch.

@Nucejoe I said it was clean, didn't say it was healthy 🙂

Its a fair comment tho, it was still on its first full wind and I was letting it run over night. Here are some pics of what it looks like on the timegrapher.

There is still some work to do - I have run out of adjustment on the balance and it is still gaining in most positions. The beat error is way out (I have not attempted to adjust a non-adjustable collet before so this will be a first). And it absolutely does not like being crown down - something else I need to look at.

Im guessing it is heading towards 100 years old? So I was pleased just to see it running again.

Good to know, thanks!

EDIT: I just realised that I didn't check the lift angle for this movement... I might need to revisit these measurements...

      Chinese clone demagnetizers

      By VWatchie · Posted

      Unfortunately yes! Magnetism can wreak havoc on a mechanical watch movement if the balance hairspring becomes magnetised. The cheap blue Chinese demagnetise-rs are useless if you feed them the wrong voltage (> 110 V), and even so, they don't work very well. The one I got when I was new worked so poorly that it drove me nuts. Eventually, I was lucky to get a Greiner Magnomatic for a little money. It's an amazing tool that can be trusted to do its job perfectly in seconds. A new one comes with a price tag of  £885 excluding tax and shipping, and if you think that's a bit steep (I believe most of us would) and can't find a used one I'd go with @Jon's recommendation.

      You definitely pick up different names from different people of all ages from everywhere. Like learning different dialects of the same language. Its all part of the learning curve of any trade.  Both those two terms describe to me perfectly that they are one and the same. After a couple of years of knowledge you can figure out what is being talked about. There are times that i get caught out with something i haven't encountered before.

      Mike, you have summed it up following the KISS principle.   Tom

      I think this is pretty typical when you have something that crosses many regional and international borders. @Neverenoughwatches yes Rich, that is the common way, learning from our teachers, however terms used in Yorkshire could easily be a lot different for tools, techniques or methods different from Scotland or Somerset. My (long winded) point is it all depends on where you first picked up the terms, if from books American watch terminology differs from English terminology and to a degree Swiss terminology. That also seems to extend to watchmaking schools. Confusing at first starting out but like anything else you get used to it. This will be why our long term members attach a glossary to new users introducing themselves as beginning their journey.    Tom
