Middle Grade Spy series, read in 1980s. Boy learns his Father is a Spy, they have unique Computer Super Watches. One book set in Paris?, bad guy drives Porsche.

I am trying to find a series of books I read when I was in elementary school, or perhaps middle school, in the 1980s. The main character was a boy who learned that his father was a spy. His father had a computer super watch of which only two existed in the world and he gave the other one to his son. I remember in one of the books, I think they were in Paris, and the bad guy was escaping in a Porsche and they grabbed a Volvo to chase him down. I don't know why that one detail sticks with me.

Michael, I copied a few book details to the topic header. Feel free to edit it.

Does his father have a dull "cover job"?
Where do they live? With mother or siblings?
