Actually.... Graham built the first stop watch (1720), which get's him the title "Father of the Chronograph", but the first real chronograph was built by Rieussec (1822).

The first rattrapante (split seconds) was built by Winnerl (1831), Nicole built the first resettable (back to 0) chronograph in 1862.

LEMANIA built the first automatic chronograph in 1947, and if you look at vintage watches much, you'll know you will find their ebauche in just about everyone else's stuff during this period of time... BUT, chronographs were on decline after the war, so no one picked up on it, and therefore Lemania never did mass production on this movement.

The first mass produced automatic chronograph was therefore Zenith's released on January 10, 1969. Of course, my preferred, as it uses traditional column wheel.
