My First Pocket Watch (Cortebert? cal. 529)

[bobtheterrible]

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...

If we can see the dial side we could confirm the movement as I found the picture

 And here is the keyless of ( the copy) Malnija 3602 for comparison if Bob did take poctures.

Thanks @JohnR725, @Nucejoe,

I have been a bit under the weather but found one of my reference pics of the dial-side. The keyless cover is missing but matches the picture supplied by @JohnR725.
