Stuck hour hand Miyota OS20

[bech312 0]

Hi.

 

I have this watch which i think is not working probably.

 

The movement is a Miyota OS20 microstepper with chrono function.

 

If i screw the crown farthest out to set the time. When moving clockwise the hour hand get stuck between 5 and 6, the minute hand keeps moving though.

 

If i set the time by moving it counterclockwise there's no problem.

 

Everything else is working.

 

Can anybody help here?

Could be that there is something (dirt, pube, etc.) interfering with the gears. You'd have to take the back off to see for sure.
