I've been overhauling a customers Omega PloProf with the 1002 movement in it.

When I took the mainspring out it had what looked like a long broken off part of the mainspring on the outside of the barrel. Its obviously not broken off.

Should I (having now put the spring back the barrel and the barrel secured in the movement) replace it?
Does it stop the m/spring from slipping so easily when the spring is more wound up?

Here is a link to the tech sheet: https://www.google.com/url?url=http...UQFjAO&usg=AFQjCNFOatz0Xk9VKfOJ3rZtzXE_vZV1Qg
If you service the barrel, you are supposed to replace the "slip ring" (part no 1000.7221) and lubricate as described.

Alternatively, you could remove the ms and slip ring, clean, clean the barrel. Apply breaking grease to the barrel wall and reinstall the slip ring. Pay attention that it is oriented correctly and the leading end overlaps the trailing end. Lightly lub the ms with lube as described (I believe you can also use teflon for this) and reinstall. When you've reinstalled the barrel, you should be able to put 6-8 full turns on the ratchet before the slip ring "slips". If you can't tell when this occurs, put 12 turns on the barrel and manually let it down, 1/2 turn at a time and count. Hope that helps.
