Our remarks

We are proud to offer you this very good vintage ZENITH EL PRIMERO Ref A3817 in stainless steel with a leather strap.

Manufactured in around 1971 this watch has the legendary automatic fast beat caliber EL PRIMERO Cal.3019 PHC build in. Together with the HEUER caliber 11 and SEIKOS cal. 6139 it was the third among the first automatic chronograph movements and maybe the most legendary.

The original untouched Tritium dial has got three metalic colored (silver, blue and grey) sub dials and a Tachymeter as well as a Pulsation scale on the Rehaute.

A cool and honest vintage gentlemen chronograph with outstanding design and movement.

This is clearly a worthy collectors item for any watch connoisseur with only around 1000 examples built.


1 year warranty though our watch lab.


- We buy watches since 1991.
