Voyagers!

Voyagers! was a time travel-based television series broadcast in the 1982-1983 season on NBC.

Phineas Bogg (played by Jon-Erik Hexum) was one of a society of time travelers called Voyagers who, with the help of a young boy named Jeffrey Jones (played by Meeno Peluce) used a hand-held device called an Omni (which looked much like a large pocket watch) to travel in time and ensured that history unfolded as we know it.
