HI all,

I have recently managed to get my hand on a Omega 321 movement. Unfortunately and the reason it was sold to me, is that the Hairspring is completely shot!!

Most of you will know it carries a breguet overcoil, which is beyond my capabilities of vibrating.

The question being, does any member know of anyone capable of doing this work. Any help on this issue would be greatly appreciated.

Completely shot means its past redemption. The spring in general is very very misshapen and the overcoil not overcoiling any more.  That said the worst problem is, its broken off around 4mm from the collet entry point.

Your best option may be to source a complete new balance and then sell your current one on eBay!

scotchwatch have a complete balance for $225. Your old balance would be a reasonable proportion of that.

Getting someone to supply and vibrate a new one from scratch would not be that cheap, it's a real pain and quite time consuming

      @HectorLooimakes an excellent point, the degree should be brilliant and more than useful but if it's not recognised, then the job options are limited.  You need to find out how many companies are willing to accept Mechrotronics.

      Hi other than testing the coil without the proper tools it will be difficult.  If you +an rig up an external supply and attach it to the cut block you may be able to pick up the pulses on the chip if not on the coil. i have attached the parts sheet for the watch 9362 which gives you the part number of the cut board assembly, whether this part is still available or not , who knows.

      Hi and welcome. First of all, check the power reserve. If the watch is runing, this means the spring is attached to the barrel arbor. If there is no end of winding, this probably means that the spring is not attached to the barreland it's outer end is slipping. In such case, the watch will run, but the power reserve will be small - about several hours

      Hi welcome to the forum. One can only reiterate the diagnosis already made by clockboy mainspring problem. But before tearing it to pieces take a little time to read the attached file to acquaint yourself with all the various parts. TZIllustratedGlossary.pdf

      B-Dip residue?

      By Geotex · Posted

      We think about these preps as "one-dips" partly because they are terrific solvents but also because the parts they are used on are often cleaner in general than many other parts. But old oils petrify, and even something like B-Dip can't clean up over-soiled parts without some extra effort, as mentioned above. There is an intermediate step during cleaning where the solvent can partially dissolve tarry residues so they have a more liquid varnish-like consistency, and that could well be what you are seeing on the coils after two washes. I wouldn't worry that your B-Dip was contaminated before you used it on this hairspring, but it I wouldn't re-use that aliquot AFTER this cleaning!
