Not a problem
That piece works like a clutch (not sure of the correct horological term) that engages and disengages the winding rotor and manual winding. It is supposed to move; it would actually be a problem if it never moved!
Try winding the watch manually, and you will see it shifts; then try to rotate the watch so that the rotor get engaged, and it will move back.
Experts, please !! (5159 perpetual)
Dear all, I just see on my brand new 5159 that this circular piece is not "centered" in the circular hole. Is this a problem ? Thanks for your help !!!...

Wig-wag pinion
This is a wig-wig pinion. A small pinion (toothed gear) is rivited to the underside. It will move inwards when you wind the watch by hand and will be pushed out of the way by the rachet wheel when the automatic mechanism is winding the watch. Try winding ...

I know from bitter experience that hand winding an ETA 2824 movement regularly will cause major problems with the reverser wheels jamming prematurely. I've had several of these movements and each one died in approx just under one year after hand winding d...

First off, hand winding automatic watches daily should not be done. Period. Hand winding any auto watch causes part or all of the auto to spin very fast in a way they are not designed for. I have often recommended against watch winders because they cause ...

Wig-wag pinion
Very interesting, thank you! So this should be the Wig-wag pinion in my 5140 with 240Q movement, exposed so it is easier to see....

Similar but different;) This is an uncoupling yoke (M1165.31-1A.A) This performs a similar function but instead of disconnecting the the rachet wheel from the hand winding mech, this disconnects the rotor from the auto mech. This is because this calibre, ...
Thanks for your very valuable input!
And I am looking forward to reading you more often, here. Best, Nicolas
Thanks for the insight! A few more questions..
Thanks for the insight! I wish manufacturers made it clear that daily winding could be a problem. I rotate my watches daily so my automatics do not have along enough power reserve between wearing occasions. I have been hand winding my calatrava for the la...
Great info and welcome. Glad you're here.
I was told by the Rolex tech guy that he usually tells people if your Rolex has been sitting on a desk for a day or two, to give the crown about 60 turns. When he first told me 60 turns, I thought that was too much but then he explained that most people u...
