Hi, I recently got a C8 M2.04 with the SH21 movement - does anyone know if both spring cans should rotate when winding?
I let the movement run down to less than 1 day reserve, when I wound the movement only one of the spring cans seems to rotate. Is this normal or is there a problem?
Thanks in advance for any advice.
Cheers,
Ian

Mine seems to wind one first and the other just follows along at an uneven rate. They don’t all turn together as I wind.

Re: Question about SH21 movement?
No they don't.
Only one 'can' (with the turbine pattern on it) rotates when winding, although the spring beneath the 'can' will wind on both.
This topic - SH21 Movement - another winding question may help.

Thanks for the quick responses guys, I guess it’s normal, the watch keeps good time, and the power reserve lasts for the full five days. Just seemed weird.

Re: Question about SH21 movement?
Ian,
I found it weird too when I first had my C8PR I couldn't see the second barrel move at all when I wound it . But likewise mine runs well within COSC and for the full five days, so I gave up worrying about it!
