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

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.

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..!

      HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....

      yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?

      Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
