Notes

Omega was one of the first watch manufacturers to employ a modular system in the manufacture of chronograph movements. This allowed them to use various non-chronograph movements, while adding a separate plate with all of the chronograph work to the back plate of the movement. This system, which is widely used today, was revolutionary at the time. Cal. 19??? SOB S S = ?Hunter?
