Its odd, it looks to be related to the Citizen 3100 and its relatives

... but more so to the 700 series.

.. other than the fact that the balance arrangement matches neither. It also shares some similarity to the 0201 (and thus to the HMT)

The 0241 has a similar balance arrangement.. and there is a Bulova version of that designated Bulova 11DP (Citizen 0241) and which Ranfft mentions as being used in Caravelle N0 (1970), so it does indeed appear to be a Citizen/Bulova/Caravell collaboration movement, but I cannot figure out which one.

I am very familiar with  the caravelle 11dp. I have several of them they are apparently a citizen 0241. I have interchanged parts between them and the HMT movement, they come in both  a seven and seventeen jewel version.But this one is a horse of a different color. it was made very early in the production of the caravelle line (1962).As typical with the brand it is cheaply cased, but well sealed. The movement is very clean and apparently unmolested. It is currently disassembled and soaking in mineral spirits . We will see how it runs, I suspect a little low on amplitude and a little high on beat error as is typical of the type.

I wonder if the tendency for low amplitude is due to tired mainsprings. It may also be just down to the design. The HMTs typically run just fine, even with amplitude down around the 200 to 220 mark. But then again, they seem to run just fine with half a sack of Mumbia potatoes in them, so they are pretty robust anyway.

      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.
