I was watching a re-run of one of my favorite TV shows from the 70s, Emergency! and noticed that one of the main characters was wearing a pretty cool watch. John Gage had on what looked to be a two register chronograph, but I couldn't tell exactly what it was...does anyone know what it is?

For those of you who aren't familiar with the show, it told the story of two L.A. County fire department paramedics, John Gage and Roy deSoto. Pretty cool and pretty realistic for the time.
