I received a vintage watch attached for a service. The movement is sitting loosely inside the case. I am looking for advice on how to fix the movement in the case so that it doesn't move around. 

 

Thanks guys,

Ferdinand

Looks like the movement ring is missing you should be able to source a replacement from a material house.

Hi Ferdinand,

 

As Blacklab says, you need a movement holder. Check what ligne is the movement by measuring its diameter in mm and converting that measurement (1 ligne = 2.256 mm). Then you know what holder assortment to get. They can be trimmed with scissors or filed down around the edges to get a tight fit inside the case. Alternatively, you can get Speedi-fit putty and build a holder but I think this product is more expensive.

Tried to find a movement ring that fits and it's proven to be quite tricky. The movement size is 12 Ligne (around 26.6mm).

I checked Cousins and Esslinger, they have 11.5 Ligne and 13 Ligne, but not 12 Ligne.

I bought the 11.5 and it's just too small. Any suggestions?

Is it possible to make a cut in the 11.5 ring and ease it out wider to fit? There would be a small gap at one  point, but it wouldn't affect the overall tightness.

 

You could possible use a jeweller's ring sizing rod - which tapers - to gently widen the movement ring.

@bobm12 Sweet. Thanks for the tips.

 

@WillFly It tried cutting the 11.5 ring, it just didn't work quite as well as I wanted.

If you need a cheap bodge...

 

get an o-ring that fits the groove, this will hold the movement central. What is important is the thickness of the o-ring, it can be cut to fit the circumference.

 

Second thing is to ensure distance from dial to caseback.. In this case you need to fabricate at least 4 pieces of 'L' shaped feet out of sheet metal. this will sit between the movement and the aforementioned o-ring with the feet of the metal bit under the o-ring, bend the tips out ward a bit to have the spring affect. This will ensure that the dial sits snugly in the case.

 

This will not work with watches where the movement is fixed to the movement ring and the movement ring itself determines the spacing of the movt with respect to the dial but in your case it should work fine.

 

This may horrify a lot of you but it works. I have people come to me with watches and when I tell them it'll cost xxx amount for parts  (plus one month wait) they will just stay thanks but no thanks. I have done the above and told them what I did and they're perfectly happy. 

 

Mostly its guys who just want to get a family hand-me-down running for occasional wear.. so cost is important. The last one I did this for was a Certina, the original spacer was a rubber/plastic thingy which I could not find...owner had no intention to use the watch regularly and accepted my solution and the fact that waterproofing would be non-existing (he wanted to keep the original crown)....

 

Basically you have to think about how the watch will be used. I have one collector who regularly brings me watches with the instruction that only the balance pivots are to be oiled. All other pivots are to be left 'dry'. The reason is he has too many watches to wear and he has found out the hard way that if not used watches will not work due to the oil gumming up. Watches will run 'dry' and since they will only see less than a days wear in a year .. well its his watch anyway..! I originally wrote 'not oiled' on the inside caseback for future watchmakers reference but he has since instructed me to desist! This guy is an enigma....retired and drives an old Mercedes and regularly (sometimes twice monthly) brings me higher end watches which he has acquired. This has been going on for the last 20 years or so and I believe the watches are local, not off ebay so I really don't know where he gets them he just smiles and says 'contacts' when I ask him. His daughter says he has at least a thousand watches..!

    • I put the original broken glass (whats left of it) behind the acrylic. This is how it originally looked like. A cheap clock but I like it. Very noisy when the alarm comes wake up guaranteed! 🙂
    • If at all possible, find a service guide for the automatic movements your work on, because the lubrication procedures may have different requirements or rely on oils you would not use in a manual wind train (in addition to the braking grease you mentioned). Some autos like older Seikos do not have a manual wind option, so the procedure of letting down the mainspring without being able to use the crown may require a screwdriver in the ratchet wheel screw and great care. Do you have an auto movement you were planning to start with?
    • I am an amateur, so there's that. I do not get fixated on amplitude, lift angles, and beat error. However, 4.8ms would bug me if it were my watch. But you must judge your own skills to appreciate the possibility of going backward. I suggest, that you button it up let your friend enjoy the watch for now. As your skills progress, come back to it and correct it. I assume that this watch has a fixed hairspring pin. Some modern watches have an adjustable pin along with adjustable regulator. These are trivial to get in beat. I own a valjoux 726 my dad gave me on my 18th birthday (a looooong time ago). I broke the ratchet wheel with an aggressive wind 4 yrs ago. I have been waiting for my skills to progress before doing a service. I am close. Your advice is well placed and I will apply it.
    • I didn’t find any anomaly to the left of the red mark…reflection? this is the balance in its pivot in the inverted assembly. i can’t see any obvious kinks  and the spring is flat as far as I can see. Either the stud screw is missing, or it’s glued in… I don’t know. I’m loathe to fiddle with it. Any further insights? Thanks!
    • Update!  I've dismantled it, cleaned all the glue off, and rebuilt and lubricated the base movement. I'll leave the chrono part for another day. It's running well - great amplitude and keeping time, but it's got a beat error of 4.8ms.    How important is it to correct this? I'm worried that the potential for making things worse having to take the hairspring off and on repeatedly to adjust this. Would anyone here accept it at that?
