Speedmaster Pro Small Seconds

[Tenags89]

Hi,

I hadn't worn my speedmaster professional moonwatch 311.30.42.30.01.005 for a few weeks. I went to wind it up last night and set it to get it ready to wear today and the small running seconds didn't start running once it was wound. I started the chronograph and that seemed to unstick the small running seconds hand. This morning the watch seems to be keeping time and the small seconds is still running. Is this an issue with the 1861 movement? My watch was serviced about 2 years ago and a new main spring was installed. The watchmaker said i was overwinding and it caused issues with the mainspring so I've been very careful not to overwind since getting it back from service.

Thanks
