This kind of spring is not meant to be disassembled. You have to clean the combined bearing with the cap jewel in place and to oil through the pivot hole.

I came across one recently in a "Mumbai special". A Favre-Leuba which had it's movement replaced by an Indian made FHF 96-4. It was done to save money. As @Kalanag says, you have to clean it in place.

Thanks Guys!

That‘s a risky manoeuver for a beginner

That's why I purchased a job lot of junk to practice on. Hopefully I won't be a fumble-fingered beginner for the rest of my life! 🙂

 I tried to clean a three pointer.  It took over 3hours to replace the little thing. I then lost the bottom  jewel assembly along with the three point springy thing. They are lost tand with gods of lost parts.    Never again. I now check the photos of movements before I purchase an ebay special.

Mike, it doesn't even seem that such a mount would provide ANY "spring" at all.

The spring force comes from the circumference being held in the setting at a different distance from that of the fingers pressing on the top of the capstone.  It looks quite effective yet not very serviceable.

Never had one.

Good luck.

    • Welcome to the forum, enjoy. 
    • Yes, the specific old tools do exist, but may be having one is not needed as they are not cheap, and also You will be able to do without it well enough. My advice will be to use regular depthing tool and adjust it for the exact distance between pallet fork and escape wheel bearings from the watch. Then remove the shellac from the pallet that now doesn't pass the ew teeth and move this pallet in. Then put the pallet fork and ew on the depthing tool and check how they lock. They should not lock when the pallet is in, but You will little by little move the pallet out and locking will appear. Then move just an idea out for reliable work and apply shellac, then check if things are still the same. You have to observe where the teeth fall on the pallets - it must be just a little below the edge between impulse and rest planes. Then You must check how everything behaves in the movement This Potence tool is so ingenious, but actually, the traditional way to do the things is much more simple. Arrange the parts not on the pillar plate, but on the cover plate. Only the central wheel will remain on the pillar plate, secured by the cannon pinion.
    • There is a tool that was made for setting up and adjusting escapements of full plate watches.  There were two styles, the picture below shows both of them.  The lower tool held a movement plate and the vertical pointed rods were adjusted to hold the unsupported pivots of the lever and escape wheel.  There was also a version of this tool that had 3 adjustable safety centres so that the balance pivot could be supported by the tool :  The other version I’m aware of is the Boynton’s Escapement Matching and Examining Tool came as a set of two or three clamps that gripped the watch plate and held the safety centres for the pivots : These do turn up on eBay from time to time.  For some escapement work, you can set up the parts in a regular depthing tool, with the centres set according to the distance between the corresponding pivot holes on the movement.  I hope this helps, Mark
    • Once you are aware of the problem, you can adjust as necessary. I have a couple of the Omega 10xx, and they are not my favourites. They seem a bit flimsy and not as solid as previous generation Omega. But I think that's true of a lot of movements from the 70-80s. For me, the 50-60s is the peak in watch movements, where the design criteria was quality, not saving the last penny.
