Balance out of poise?

Thank you in advance for your help. I picked up a 16610 (2006) with a +20 second daily rate. Took it back to the seller (jeweler with a “watch guy”). Offered to regulate the watch. 20 minutes later, he showed me watch running at about 1 second fast. Let the watch sit for a 24 hour period and confirmed excellent time keeping. Wore the watch and noticed an increase, depending on the day, 4 to 8 second increase per 24 hours. I intend to have it serviced in the near future, and I don’t have access to see if watch had been serviced recently.

Could the watch be out of poise? If case back interior shows a recent service date, could the issue be microstella unequally adjusted and would it be easy to balance out the wheel without too much trouble (ie. significant hours spent)? Would you tell a watchmaker that the balance wheel may be out of poise or is that checked during servicing? My concern is that the person doing the adjusting wasn’t careful with equal adjustment of the balance wheel.
