End stone problem.


WildBill

Recommended Posts

Hi, I was in the process of oiling the end stones, I didn't realise they were in two pieces, and I have lost one, maybe its possible to get a replacement..

The top shock absorber went OK, although I found it very difficult to do..."Being the first time" When doing the bottom shock absorber I lost the flat one,

I  also broke the small retaining clip....realising this is going to a nightmare of a job to do....Advise Please.

Everyone's favorite job, replacing shock springs. I hope you're up for a challenge.:D

Sometimes the endstone for the top shock absorber is thicker (taller) than the one on the bottom shock block. keep that it mind or you might just break some more shock springs trying to close them back up. 

We should be able to help you out once we get that information rogart mentioned.

Looks like you are in luck. For the ST96, you can order the incabloc settings and the stones and springs from Cousins

https://www.cousinsuk.com/category/st-movement-parts

https://www.cousinsuk.com/PDF/categories/1305_Incabloc By Factory - Standard.pdf

https://www.cousinsuk.com/product/inca-end-stones?code=INCA12111

The inca catalogue is in French to make it all more exciting, so Bloc Dessus = Upper complete block (the one in the balance cock), Bloc Dessous = Lower complete block (the one in the main plate). Pierre = stone and Ressort = spring.

121.11 is the upper shock (dessus) end stone, the lower (dessous), in the main plate, would be 722.11. Just type 722.11 into the Cousins search box.

As mentioned above you may have broken the spring by trying to fit the wrong jewel or fit it upside down, so be sure you get this right.

Lots more info on the inca website here, http://www.incabloc.ch/en/huilage.php but I can’t see the jewel sizes to measure up your end stones and check.

Is that it Inca 122.11- highlighted in yellow, that's the lower shock on main plate.? so looking forward to

putting the spring in "not"...will order it today...thanks for help....

Putting those springs in is one of the trickier tasks - I really struggled when I started. I found it useful to use Rodico. Put some above where the spring is to go, stick the spring on to the Rodico, and slide it down.

I have contacted Cousins requesting 722.11 for a FF ST 96... The lower shock stone spring got broke trying to them out, the spring looked fatigued and in poor condition, I just helped it on its way..   Am I right  the jewel is in 2 parts 1 part  stay in its retainer, the other part that you oil that goes on top, and the spring keeps it in place.

Yes, have a look at this (what is shown as 'The Mobile Bushing with it's jewel' is one piece')

I have to get the broken piece out yet.....its it just fitted into a slot, so it should just pull out with tweezers....."Hopefully"

To get the spring out you may have to push the setting out a bit to free the slot.

The whole setting is out already I think , just the piece of broken spring remains...

Don't know how I'm going to see what I'm doing....I have only cheep loops the most powerful one is 15. just had a look at the broken

spring my finest tweezers seem far to big, might have to do a job on them.

Hi Stuart, I managed to get the end stones for my ST Movement, I don't know how you find the right number ie 722.11 for the lower end stone...My question is I need a spring as well but know the right one to get, can you tell me code no. of the one I need ...Also I must mention on getting out the broken spring, (not even sure if I've got it out) I may have damaged the area where the spring goes.

Apart from getting another Main plate complete with the jewel in place...Do I have any other options,.?

You can identify the individual parts from this table: http://www.incabloc.ch/en/systeme_incabloc.php

So you will see 722.11 on the row for ST 96 under the column headed “pierre de contre pivot dessous”. If you need the spring for the same fitting it would be “ressort de contre pivot dessous”, which is 770.03

If you have damaged the area where the spring goes, then that is the “bloc”, which can be replaced by removing the u shaped clip from the other side of the plate. The nomenclature for the spareable parts is here:

    • Does anyone knows what size case a need for a dial diameter 20.60mm?
    • Sounds like the story with my Rolex. Poor (expensive) job done by an official Rolex dealer with an "in-house" watchmaker, hence I learned watchrepair and did the servicing myself. Same story as I learned with the Omega 861, again poor job by an "in-house" watchmaker by an official Omega dealer. Once your watch goes through that back-door, you have no idea what is going to happening to it 🫣 Quite nice that the sent back the parts which had been replaced !
    • yes that's definitely not right at all. I have a picture one of my friends has a Omega coaxial there was having issues to lose asking me where he should send it. As that's a specialty watch I suggested the service center. When he got it back he sent me a picture so the replace the dial as you can see the hands the mainspring barrel and I think the price was really quite decent considering all the stuff they can replace. So I do know they do change the barrels but the other person I worked at the service center when I would ask questions and unfortunately I can't remember all the answers. I think a lot of the changing a parts is at the discretion of the watchmaker. Plus I don't know enough about the chronographs and whether that would be considered a vintage watch? I take some of the vintage watches may have been sent directly to Switzerland or another service center. Obviously with a watch like the one down below they probably have a infinite supply of parts is its relatively modern vintage stuff becomes more interesting even the watch companies don't have necessarily infinite supply of parts. But no matter what the watch shouldn't disintegrated six months that's definitely an issue.        
    • glad it worked out, those ESA movements are obsolete but new old stock is still out there, now that you know the make/model you could also do a cross reference to see if something more current would line up with the dial feet and hands...for future use if needed 👍
    • I wish they would have done so in this case. The whole story went like this: I sent my speedmaster to an omega service center about 10 years ago (at that point of time I haven't even started watchmaking). After the watch came back to me it had only about 6 months wristtime until january 2024 (not fair for this nice watch but the other pieces of my collection want wristtime too 🙂). So my conclusion is that the barrel was already faulty when it came back from service, can't imagine that amount of wear in 6 months wristtime. In january 2024 the performance on the wrist was quite bad, so I decided to have a look by myself. I have to admit that I didn't check the barrel close enough as I thought it must be ok, couldn't have issues after official omega service. That was a mistake, I will learn from that. Follow the golden rule: Nothing is certain except death and taxes.
