The race for the First Automatic Winding Chronograph

John DeVore (DeVore Fidelity) happens to be a horology 'watch nerd' & a knowledgeable one too.

Here in this (Part Time Audiophile) The Occasional piece, he chronicles the story of the world's first automatic-winding chronograph wrist watch.

Interesting especially, Seiko's part in this history & also the significance of the Zenith calibre 'El Primero' when quartz decimated the traditional Swiss watch industry.
