Service question

I recently purchased a 1998 Speedy with an unknown service history which is my first Speedy. I took it into a local watchmaker who has been recommended on vintage watch forums for him to see if the watch needed a service. He took it into the back and appeared to put it on a timing device then brought it back out and said it was running perfectly and didn’t need a service. I would have thought it would have at least needed to be lubed or had the gaskets replaced. Should I get a second opinion, or do you think I’m overthinking this.

Far from beeing a watchmaker: As far as I know you can get a good estimate of the movement condition by using a timegrapher:


In this video you can get a lot of informations on that (if you like)

I'd say get a second opinion. If you want to wear daily and have.no service history I'd want my watchmaker to at least open it up and check if it's dry or not.
