    Strange behavior in old movement

    Hi, Thanks to Watchmaker and WLS1971, two excellent watch sleuths, two out of three ongoing identification questions have been resolved. A Derby 33 and a Bifora 102, no common movements on my list. Had never heard of the brands before. But amazingly enough some parts are available and I have some incoming. But this headache remains... I just noted a small imprint on the balance cock (a "V" it looks like) and was wondering if that perhaps rings a bell somewhere...? A close up photo is attached.

    Movement id help again...

    Spot on ! The Derby 40 on Ranfft is close on the key-less stuff but looks more modern otherwise. But 17-jewels (https://17jewels.info/movements/d/derby/derby-33/ ) shows one that's identical except for the the shock proof add-on that my movement doesn't have. Derby can't have been a large manufacturer as there's not much info to be found (so far at least) . And the name is strangely English sounding for a Swiss origin or what do you say? And there seems to be spares around.. Many thanks, deeply appreciated!

    Thanks for trying Watchmaker, appreciate that! Kinda irritating to get stuck when the balance is actually and unusually ok. I guess I'll have to keep my eyes open for a potential candidate to replace the escapement wheel.

    No luck with movement id...

    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.

    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... :-)

    That’s a new one for me! Can you point me to some more documentation? Sent from my iPad using Tapatalk

  9. 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... y Sent from my iPad using Tapatalk

    Strange behavior in old movement

    Hi, Not giving up on this one yet.... Here are a couple of photos that hopefully can help to id this movement. The key-less part is in my experience somewhat unusual as the yoke and spring are on separate sides of the winding stem. I usually see the spring sitting right beside the yoke. Maybe this ”feature” can be of guidance....? Sent from my iPad using Tapatalk

    attached is a close-up photo of the key-less works. I flipped through most of the 10,5"' size movements on Ranfft but couldn't find anything that was close. The yoke seems unusually short and straight compared to most designs I see on Ranfft. Where does other people find designs and pictures to compare against?

    forgot to mention; it's a 10,5"' size movement if that helps. Maybe there's a predecessor from AS that fits..?

    Hi and thanks for the feedback. But I can't get that id to work out with the other features of the watch as it's coming from a tank style watch that seems to be from the 30's. And there's no shock protection either, which I would have guessed would be there in a 60's design My assumption is a much older movement... What do you say...?
  14. Working on an old movement just to (after cleaning) find that one of the escapement wheel pivots is gone. Another issue is that someone have, as it appears, replaced the pallet fork cock and in the process ground down the ”new” one to make the height fit. But...the jewel hole does not match the lower one in the base plate 100%, making the pallet fork sit a bit tilted. Wonder if that ever worked...? Talking mod’s I note that escapement wheels for this type of basic design are pretty similar. If I find one that is just slightly too long or short, would it be feasable to shift the jewels slightly in or out to make it work. I realize it’s not going to be easy to get a decent end shake.... In any case, if there’s someone who can id the movement, I would appreciate it. Not likely there are spares around, but who knows. I assembled the important items to hopefully make the id easier.
