In the past I was mistaken in thinking that the watch Del Griffith, played by John Candy, in Planes Trains and Automobiles was the Casio A158. Upon further research, it appears that this is the Casio A159.

The main difference between between the A158 and A159 are the bracelet. The 158 has more of an h-link style bracelet while the A159 has a 5 piece bracelet that apparently does not have as much adjustability.
