Greetings to all.  My name is Todd.  Married with children (great show right!).  Long time admirer of mechanical watches. Now taken up the hobby of repair.  Why?  Educated at Purdue University (Indiana) and Lawrence Technological University (Southfield, MI).  29 years in automotive industry, first 15 in product development.  So basically my mind has always been curious about how things work.  I see how the evolution of the mechanical watch has occurred.  Amazing.  I have inherited an 1800's swiss cylinder escapement that was non-working.   It is my first project and I am happy to say that it is running again now after some creative repair in the main spring housing to click interface.  However, this classic is missing on the dial side the reduction gear for the hour hand and the actual minute hand.  Seconds hand and hour hand are ok.   As reference, the movement OD is 44.9mm, the cannon pinon OD is 1.15mm, the seconds hand shaft is 0.6mm and the post that supports the missing reduction gear is 0.49mm.  Basically I could use some hints where to search for parts!  Attached are some pictures to compliment my words.  I appreciate in advance any advice.

Hello and welcome to the forum.  the watch is a five bar french/swiss made cylinder movement  you will probably have to trawl the net/ebay for bits.  I believe Old Hippy mentioned that these are the devils own find bits for as they are almost individualy made and as such parts dont interchance easily or not at all.

Hello and welcome. I'm a reasonable newbie myself, servicing I'm getting good at, repair is a different matter. 

Unfortunately the parts aren't always interchangeable, in fact seldom are. I've learnt the hard way.

      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.

      By RichardHarris123 · Posted

      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.
