Just picked up a 16013 with a 3035 movement. The watch had been running fine since Thursday. Well, yesterday, all of the sudden, it stopped.

 

After noticing that it had stopped, I gave it a few winds, reset the time, and it went back to working. This happened a few more times throughout the day yesterday.

 

Today, I opened the caseback and immediately noticed the the oscillating weight was rather tight to turn (WAY too much resistance). The balance was not turning either. So, I gave the balance a puff of air in both directions. It wouldn't turn in one direction. It would in the other, but on return, it would stop as though it were hitting the fork. 

 

ANY insight into this would be appreciated.

Hi Billiards,

 

Welcome to the forum.

 

I would check the balance jewel for wear/chipping/alignment and also the pallet fork since it seems the jewel is falling from its place in one direction. I would also check the hairspring and even the incabloc setting for wear. Won't harm any if you can run it through a good cleaning and relube.

 

Also, I will check the bearings on the rotor. Mark has a video of a 2824-2 movement where he corrects the rotor issue by replacing the bearing. In any case, let's hope some other, more knowledgeable member, post a better solution.

Hello!

I would take out the balance and then, with a dry oiler, push the pallet fork in both ways. It should 'jump' in both ways. If it doesn't, then there is another problem. Put some tension in the mainspring and try again. If it is not dirt in the movement then there are problems with the pallet stones.

All the above would be solved with a thorough cleaning and oiling.

Good luck!

Exactly and also:

and the jewel that goes in there:

which might need adjustment/fixing/replacing.

I was supposed to play pool this evening. However, if the weather stays bad, I'll probably open up the watch again and see about getting it repaired.

 

I'm wondering if the hacking has anything to do with the balance not oscillating. Thoughts?

Just took a side shot of the balance staff jewel... Looks like it is either chipped or worn (unless it's made to have a groove in the middle of it).

mmm, I don't know but the pallet fork seems to have a leg shorter or it is maybe the pic. It might have caused the wear on the balance wheel jewel... I'd wait and see if we have another opinion!

Just spoke with the seller. I told him I'd be willing to accept any one of 3 options.

 

1) He could refund me $600-700 USD and I'll take care of getting it repaired.

2) I'll send it back at his expense and his watchmaker can repair it and send it back.

3) I'll return the watch for a full refund.

It does look like there is an issue with the fork as Bob says. Also the roller jewel also looks like it may have a bit of damage.

I personally would go with option 3 and get a full refund.

So would I - a watch of that class and cost is going to be expensive to sort out and it should have been in good condition in the first place.

 

It's sometimes difficult, when a watch isn't quite as you hoped it would be, to decide on the level of "not-rightness" and what action to take. If I buy a real vintage watch, e.g. one from before, say, 1970, then I expect one or two problems to occur now and then.  But occasionally, one I've bought has turned out eventually to be a dog. In those instances I usually cut my losses and sell it on as "spares or repair".

 

The little 1939 Unitas I have, which had a bust hairspring, turned out to be a problem, as some of you know. The ratchet wheel screw sheared and damaged the arbour when trying to replace a bust mainspring. Luckily, a slight touch of WD40 allowed the broken stem to be extracted. The problem was finding a replacement arbour and screw - the mainspring replacement was no problem. I solved the parts problem by finding - purely by chance - an identical Unitas 173 head on eBay!

 

I took that trouble because it's a beautiful little watch and worth the effort - but others would have just been got rid of.
