The case screws are 1mm thread. Are you putting new threaded holes in different locations or have messed up thread and want to retap them?


Thanks a bunch to both of you! :-)

I’m working on a vintage movement with case screws that are pretty much obsolete or $50 per piece. Luckily, the movement has premade holes in the mainplate to use different mounting positions and I can tap the holes for more modern screws that are easy and affordable to source, hence why I decided to go for widely available ETA screws :-)

There are assortments of these for a reasonable price. I have a feeling that the entire range of assortments is not made anymore so I'll be grabbing some for myself.

In addition to the technical communications from eta they used to have available the manufacturing information sheets. These are interesting technical documents with more of the technical specifications. I rather like him because the timing specifications are given. If you scroll down far enough there is some movement size information casually on not seeing the screw size but it might be there. Then this is for the 2824-2 version versus the version you asked for which I don't have a manufacturing information sheet for.

      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.
