Hey folks,

The rotor spinns on my a7750 while winding... a lot ;)

Bought that used... Not described. I am happy with the watch. Would you recommen returning it? ( I don't want to) Will it cause problems in the future? While winding as well the stem "lost" catch with the movement... slipped 1/4 turn or so. I did not use force at all. Very slowly winding... very.

Is this watch going to die on me sooner than usual? Can I fix the rotor problem ( I am not good with watch repaid ;) )

What I found by The Zigmeister about this problem:

I think your reversing wheel click spring is not working. Many of them are defective, I see it all the time.

The reversing wheel isolates the rotor from the mainspring, and the click is what prevents the mainspring from feeding back into the rotor.

A simple test is with the watch flat in your palm, wind it slowly, if you feel the rotor spinning, your reversing wheel click is not working.

The watch will still run, and will sort of wind automatically, but you will have very low power reverve. The good news is that the click is easy to access and fix. The bad news is that accessing it requires taking the autowinder bridge off the movement, and assembling this part is quite difficult.

What would you recommend ?
