Hi all, my neighbor bought this at a local thrift shop and it wasn't running.  She's elderly and I told her I would look at it for her.  I got it running pretty quickly and at first it appeared like it just needed a service, but after putting it on the timegrapher it seems to be my old bête noire, a kinked hairspring...  It appears that the regulator curb pin is contacting it which is stopping the watch occasionally and also affecting timing.

Anyway, the watch is a 17J movement, about 17.5mm in diameter.  It's shock protected and signed M. Herbelin which is Michel Herbelin, a brand that still exists today.  The movement is stamped U6 76 under the balance and also 1-76 by the crown wheel.  The balance cock has both rate and beat error adjustment.  It's stamped Made in France, so I'm assuming it's a French rather than Swiss movement.  I'm not finding anything in my searches so far and I'm hoping somebody recognizes it.  She's a nice old lady and I'd like to get it running for her and be able to tell her what it is.  Any suggestions on the best way to get that hairspring correct are welcome as well.  I'll have to get it stopped (no hack) to get a clearer photo of the bend.

Here's a photo:

Gents, I believe it is indeed that movement.  What an amazing help you have been.  I didn't think it would be an ETA movement since it was stamped made in France, but I guess I shouldn't be surprised.  I found a very cheap hairspring on eBay and have ordered it and should have this running better in no time.

      Can someone please explain watchmaker service mark interpretation?

      By Waggy · Posted

      All I do is use a fine marker (sharpie) to put the service date on the back cover, this way it can be removed with some IPA and does no permanent damage to the watch. I'm in two minds about the whole service marking thing, sometimes it's good/bad to see the markings on the watch case back as you know it's been worked on and vice versa. However, if I took my car in for a service and the mechanic scratched some code into the housing of my engine I wouldn't be too impressed. Hence, I think my sharpie solution is a reasonable compromise.

      Movement holder made with 3D printer

      By Waggy · Posted

      hmmmm.... maybe there is a way to skin that cat 🙀 let me think on it... unless anyone else has any ideas? I left the opening in the side of the base and ring quite large to maybe allow you to grip the crown, but appreciate this may not always be possible, especially for small movements where the crown will not extend past the outer wall of the holder. I noticed this also, but after using the holder for a while I noticed that the ring/holder began to wear into shape (rough edges/bumps worn off) and the size became closer to the desired movement OD. Maybe with some trial and error we could add 0.5 mm (??) to the movement OD to allow for this initial bedding-in?

      Vintage pocket watches from e-bay (winding stems needed)

      By Mallard · Posted

      Hi nickelsilver, thanks for the great explanation and the links! I'll take a good look in the article.  Especially this is great news to hear! Looking through forums and youtube videos I was informed to 'fist find a case and then fit a movement for it'. But seems that's not the case for pocket watches at least?  I guess I should be looking to find some 'male square bench keys' for now. I was thinking of winding the mainspring using a screwdriver directly, but I found a thread that you've replied on, saying that it could damage the spring.

      Murks, The rate and amplitude look OK, and the amplitude should improve once the oils you have used get a chance to move bed-in, also I notice that you are using default 52 degrees for the lift angle, if you get the real lift angle (assuming it's not actually 52) this will change your amplitude - maybe higher, maybe lower. I notice that the beat error is a little high, but not crazy high. At the risk of upsetting the purists, if the balance has an adjustment arm I would go ahead and try and get this <0.3 ms, but if it does not have an adjustable arm then I would probably leave well alone. Just my opinion.
