Zenith El Primero Pilot/Diver Chronograph ref: PI 6734
In 1971 slim and elegant was not on Zeniths mind when they made this beast! At 44mm w/o crown it is a impressive statement of a brute tool watch! The spectacular calibre 3019 PHC was the crowning achievement of Zeniths engineering know how, when it was launched in 1969 being one of the first automatic chronographs and a impressive if not excessive beat rate 36000A/H. This example is offered as a nice survivor.
Case ref: PI 6734 in fair condition, never polished with normal wear from use. Original crown and pushers. Bezel is a Zenith service bezel. Case size 44mm w/o crown. Movement in very good condition condition serviced by me in November 2021. Se service photos here! Curently on a NSA bracelet in good condition.
