Based on one of Heuer's historic chronograph designs, this Monza calibre 36 houses one of the worlds most famous automatic movements; the legendary Zenith El Primero that also powered the first automatic Daytonas! Based on a 1930's design and borrowing the name from a famous Heuer creation that celebrated Ferrari's 1975 championship win, this vintage style cushion shape chronograph comes fitted to an unworn alligator strap with folding clasp and is complete with its original box and papers.
