Haven’t been very lucky with my recent findings and getting them identified.

 

But I’m not throwing in the towel yet; here’s another peculiar one for you to look at.

 

Both movement and dial has a symbol ”3” insite a diamond. At least that’s my interpretation of what I see. And the no. 481 is stamped on one of the bridges.

 

Can’t find any references to the symbol or no. And hoping that someone more knowledgeable can help.

 

Photos are attached.

 

And btw. Both balance staff pivots are gone...

Not a bad shout there.  The bridges look pretty identical but the keyless works are slightly different.  Possibly another generation of teh same movement?

Until recently it was possible (but difficult) to view the Catalogue Officiel on Ernst Westphal's site, but they've revamped it and it's no longer there.  These come up on eBay or you can buy an electronic copy.  Have thought about it a few times, but then thought that mostly I'm looking things up because I like the challenges that others set! Other sources may be available, but see here http://www.watchmakingbooks.com/ebooks---pdf-formatted-books.php#!/Swiss-Watch-Parts-Catalog-1955-edition-digitally-enhanced-PDF-eBook/p/19103710

Hi @bsoderling That sure looks like a '3' ... but it's actually a 'Z'. This then makes it a watch made by ZentRa.

Here's another watch by ZentRa with the symbol and the name of the company on the same dial to confirm this: http://www.ranfft.de/cgi-bin/bidfun-db.cgi?13&ranfft&0&2usau&1259164803&

Here's some information on the ZentRa brand in general: https://www.watch-wiki.net/index.php?title=Zentra 

This site mentions that ZentRa used PUW, A.Schild or Miverva movements in the main. I also guess that, as a German watch brand, they might have used other German movements which might help steer things in identifying your movement. Are there similarities to a Junghans 680.71 for instance??

Hi,

I think we nailed it! 

The Ranfft link provided by Watchmaker also mentioned that Bifora movements were used by ZenTra and a quick search on Ranfft fo Bifora point me towards the Bifora 102/1 (without some jewels, just as mine) that seem pretty identical. 

So now on to finding a balance staff for Bifora 102 (may not be that easy ...)

Thanks guys for all the help here!

And if you have spare time to waste, there's always my two other id cases alive here on the forum... :-)

Thanks Watchmaker, I'll try to remember that. Not too used to likes and stuff like that. You're talking to a guy that doesn't even have a Facebook account, if you can believe that :). 

And thanks to Busakaz. I presume the catalogue pages are from one these famous Bestfit or similar catalogues I hear so much about? In any case it's definitely my movement in there.

Regarding the balance staff, both Cousins and Balancestaffs.com refer to this as Ronda 370 whereas the catalogue and Ranfft calls it     U 371.

Ronda I know as a manufacturer of many items in this area but the "U" is one I don't have any reference to and would appreciate some education on.

      What is this tool !

      By mikepilk · Posted

      I was pleased to pick up a selection of some tools on ebay (v cheap 🤣), and they've just arrived,  I've been looking for a crystal press for a while, and this one is ideal But in the selection is this thing - what is it for?  (it's about 3" long) Something to do with stem tubes?

      You'll have to strip it back anyway.

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      I think I've heard that more than from just Alex. That doesn't make it right though, but I'm convinced i saw some literature diagram explaining why to do that. There must be good info here in the archives, I'll have to have a dig around.

      That will mean dismantling the gear train, which with 5 pivots to align was a pain. Probably going to have to though. I'm convinced it's something to do with the great wheel.

      Epilame / Fixodrop

      By VWatchie · Posted

      As far as I know, the only time an epilame treatment has potential drawbacks is when something is rubbing on the treated part w/o lubrication in between creating abrasive dust. That is, I don't believe in the method of "running the watch to make a groove through it first in the pallet stones where the lubrication is then placed". So, I think the rule would be; do not epilame treat parts where rubbing is going on without lubrication. Other than that I don't think we have anything to worry about. That said, I'm not an expert, and I'm always happy to learn more. Has any other repairer than Alex suggested or explained the "making-a-groove" method? My impression is that it's just something he constructed in his mind. I have not perceived it as a generally practiced method. Again, I could be wrong!
