It definitely stops. I don't really notice bad amplitude in any particular position, but I looked at it under a microscope and it appears that the escapement wheel jewel could be worn because it looks like the pivot wobbles a bit in the jewel bore. Sorry, I'm not great with technical terms here. If it is that jewel, it will more than likely cost more that the watch is worth to have it professionally repaired.When you say "Stops on occation" do you mean that it actually stops or are you assuming it is stopping because it is behind when you check time?
- It could be as simple as the hands slipping behind because of the low resistance you experience when setting the watch!
When you test it on a table do you check it in various positions i.e. Dial up and down and pendant up, down, left right?
- If it slows down or you have bad amplitude of the balance in one position, that may be a hint to what's wrong.

Hi Skutt and Graham, thanks for your replies here and your help. I will take the watch apart again and inspect it. I will be retiring in a few months and it would be a great project for me....I will need to fill my spare time. I also found that the movement does not fit very tightly in the case...it rattles a bit because it's held by only one screw. I also noticed that when I removed the dial, there was no gold washer on the hour hand minute hand shaft. Could that also be an issue?Hi Skutt,
I wasn't sure which wheel he was meaning, so I thought we should be clear on some names to start with.
Regards,
Graham
Yes, cannon pinion....sorry for the bad terminology. Thank you for the replyThat is probably the cannon pinion which would not be gilt so consider it normal.
That is probably a brass washer called Dial Washer which function is to prevent the hour wheel from rising and disengaging from the pinion on the minute wheel. I don't think that will cause the watch to stop and the minute hand should basically do the same........I removed the dial, there was no gold washer on the hour hand minute hand shaft. Could that also be an issue?
