So I attacked this nice old Waltham again today and it works upside down. One of the bottom balance end cap Screws fell out and things just are not right with the bottom jewel and end cap. Any suggestion on how to proceed. I think both Screws have stripped the plate that holds the lower cap jewel and end cap.7ad674e8b7ce9b7557d359036fbc880e.jpg

ok, you talking about the upper plate balance jewel setting? Which is the lower balance jewel set, as the upper set is in the balance cock, so I am confused by your question and your pictures which shows the keyless works.

Based on past experience, also do a very close inspection of the balance staff, and the jewel as a damaged staff can cause the same issue. I had one that looked like something chewed in the lower pinon, and upon further inspection, the jewel was damaged in the I.D. and was causing the issue.

I want to verify that the serial number on the lower plate that is visible is the complete number because I want to look up which model of watch this is?

Then your picture and description I agree is confusing plus the picture itself is very confusing as something isn't right?  So the picture looks like an 18 size full plate watch which would have the lower balance hole jewel fastened to the upper plate. So it looks like a jewel assembly next to the setting parts does not make any sense at all? I've circled my confusion in the attached image.

It looks like somebody has modified this watch for unknown reason it would be nice to see the plates separated.

      Omega cal. 565 - low amplitude

      By RichardHarris123 · Posted

      @JohnR725 has pointed out many times that the Swiss don't care about amplitude, the timekeeping is the most important.  Give yourself a  pat on the back, great beat error and timekeeping, nothing to be disappointed about.

      I'm bothered but I agree he's a busy man and I don't want to bother him.  In the meantime, we really do need to have other ways of contacting each other

      Second hand watch market.

      This is as complicated as epilame, too many unknowns. The life expectancy in the UK is circa 80, so most people from 1944 or earlier are dead.  Assume they had children at circa 20, they died in 2004. Their children started selling 1944 watches in 2004, so pre-1944 watches must be getting more rare.   It doesn't work though because as you stated some were sold as tat, but since watch prices have increased people have decided to sell when they may not of done in the past.

      Questions about my Bravingtons Renown Mantel Clock

      By Michael20 · Posted

      I was wondering whether anyone could assist with some questions I have about my latest acquisition, which is a two train ‘Bravingtons Renown’ mantel clock - Pics attached I have done some reading about Bravingtons and believe they sourced movements from various suppliers, so I wondered whether anyone recognises this one. I have stripped and cleaned the movement and the clock is now running well, but there are a couple of dodgy brass springs that I would like to replace. I haven’t found anything suitable searching the internet so I wondered does anyone know of a supplier that might help. Last question is about the veneer on the case, it is generally in reasonable condition but there are a couple of patches on the top where the veneer has lifted. So far, I have tried to reactivate the existing adhesive by heating from below and above with a hair drier, then clamping for a day or two. It has improved slightly but the bulge is still visible. I’d be grateful for any advice if anyone has dealt with this sort of repair before.
