Hi

I stripped down a 689 movement, everything went well untill I tried to remove the jewl caps.

I is my understanding the jewl with the little brass retainers are two piece, a regular jewl and a cap ?

This is my first time digging this far in and now am paying the price. The first retainer I tried to gently squeeze like I have seen on the videos,  I immediately destroyed it. Gave the other side a real good look and found it to be a quarter turn to loosen, I accept my mistake and move on but when I finally removed the jewl it was one piece,  the bottom has a hole for the pivot and the top is flat with a brass ring apparently holding them together.

Are they worth the effort to take them out ? I'm not sure how to go about cleaning them properly, I feel if I put cleaner in the hole it will not flush out and of course ruin any oil I try to get in.

Next step is the escapement wheel jewl, that clearly has a little C clip holding it in, I released one side of the clip and it's gone, never even seen which direction it was headed. At this point I now have a parts watch and that's a shame because it ran fine before I tried to improve it.

The escapement jewl will not come out I have pushed pretty hard from the inside and it seems to want to stay put.

I guess I'm really looking for a identify weather or not to fool with them and if I get one out and don't loose the clip can it be cleaned ?

Thank you, Tom

It is unusual for them to be one piece. They do look like one piece but separate normally during the cleaning. Also some watches the top & bottom jewels are slightly different so keep them separate.

Figured it out. They are not one piece, this watch is loaded with fresh oil and everything is stuck together. I'm not the first amateur to fool with this one.

Anyhow learned some pretty good lessons on it, it was worth the trouble.

      Parts sourcing for FHF 180 movement

      By JohnR725 · Posted

      I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.

      Actually, this could be the issue. Drag from the module could be overcoming the cannon pinion. It was definitely not at the point that the driving wheel was loose on the cannon pinion, it took a little bit of effort to rotate it when applying the grease. Maybe I need to look again at applying oil to the pivots.    Yeah, it's very annoying. I don't want to give up on it, so back on with it over again until I catch a break.

      The sping is not pushing directly on the cap, but is pushing against the spindle. So, even if the usual black cap is replaced with the micrometer cap, the spindle is still pushed up.

      But he tells that the micrometer cap doesn't screw into the spindle. How can the spring push the spindle up if there's nothing to grip? There is a screw visible on top of the micrometer cap so should it be able to screw into the spindle? I'm feeling really dumb now. Does anyone manufacture that cap as an aftermarket item? Might be worth investing. Ok so the spindle is different, now I get it.

      I suppose? If it worked before and it doesn't work now I guess the question would be why does it not work now? That would come back to if you did not have the chronograph module on will it work or is the chronograph module sucking too much power out of the watch basically 99 usually when they go bad you can hold on the tube part and usually just spin the wheel because it has zero holding at all so usually when they go bad they go bad very bad. You should build hotel when you set the watch as to whether it seems to have any friction or not. I'm just wondering if the chronograph module is the problem.
