Is this all with or without engaging the chronometer? My speedy pro always runs a tiny bit faster without de chronofunction engaged.

ChronoGRAPH.

You own one, yet don't even know what it is? 🤦 🙄

Assuming the movement has been serviced recently, may just need adjustment. I always try to see if there is erratic difference in time day to day as it may be a sign of other issues.
