Three point shock spring?

How do you deal with one of these? These are on one of the practice movements I got in a recent job lot purchase.

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.

So obviously the balance with spring has to be removed from the cock to oil the jewel. That‘s a risky manouver for a beginner.

Thanks Guys!

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!

These are cheap, poor quality, movements. So good to practice on.

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

 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.

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.
