Not the normal watch winder question...

[CardShark]

.... as in I'm not looking for a recommendation or if they're really needed, but something else.

IIRC there was a thread some time back about winders and the fact that some autos aren't suitable for them as they won't wind when being spun by a winder.

Now I can't think of why this would be the case, but could it be? Did such a thread exist? It's late and I'm a bit

A question was asked in the I want a Monster thread about this

I'd be interested in this as well - as my 3 automatics behave slightly differently in my different wonders.

I'm also after someone who can repair the bloody things... (My Frank Mueller doesn't like being in a winder either).

It could be in relation to watches fitted with Valjoux 7750 movements, as the rotor mechanism only winds in one direction, but 'freewheels' in the other ... So if your watch winder is spinning the rotor in the freewheel direction, it won't wind the watch.

It's also the reason why 7750 equipped watches have rotor wobble ... If you move your hand in a certain way as to spin the rotor quickly in the freewheel direction, the entire watch physically wobbles on your wrist. It's a pretty cool characteristic!

It's definitely this reason. If you have a winder that only winds in one direction it will not be enough to keep a 7750 based movement wound. You have to have a winder that will compensate by winding double in the correct direction. This is also true for a lot of cheaper movements, 21j miyota clones etc where they only wind in one direction. In fact in some of those you can actually hear the ratchet clicking as they wind in one direction, and then nothing as they freewheel in the other.

Ah yes, that makes sense and rings a bell
