Is it normal?, Crown turning back when I wind the movement

[rckh]

Dear All:

I would like to ask whether it's normal or not? Swiss ETA 6479 with dagger swanneck-movement; when I winding the crown keep turning back a little bit slowly. Seems the movement keep good time. I own 2 of this movement; however; the other one haven't got the kind of problem. Dealer told me it's normal......any idea?

best regards,
Raymond

No, thats not normal. Dose it keep turning or dose it only turn a little bit?

If it's just a little bit, it sounds like the click spring is sticking and not locking into the ratchet wheel as it winds and is letting it slip a little bit once your done winding it.

nothing major, but if it keeps unwinding and not stoping you'll need to get the click spring checked out probly replaced.
