Hello guys, am curious if anybody can point in the right direction of a watch smith, preferably USA, even more preferably California, that would be able to work on a Zenith El Primero movement that's currently running slow.  The power reserve is still good I'd say 45-48 hours but it is noticeably slow.

Thank you

Thanks DVN, I have an El Primero that is need of servicing, regulating, thanks
