The 70s stand for daring and futuristic design concepts including this El Primero chronograph with its striking tonneau case shape. Due to its masculine case, the watch is also called "Defy" coming from the French word "defier" (to defy).

In addition to the well-known stainless steel variations such as the reference A781, A782 or A783, there was also this luxurious reference G7813 with a solid 18K carat yellow gold case. It is known from collectors' circles that this reference was produced in a very small number of around 100 watches. After 50 years, only few examples have survived and even less then that are in good condition.

Other pages contain instructions for use of the chronograph in Italian. The original accessories also include the red round vintage Zenith box.

The watch is powered by the legendary El Primero caliber 3019 PHC, which was presented in 1969 as the first automatic chronograph movement. Due to the quartz crisis in the 1970s, production was stopped in 1976. But twelve years later, Rolex used this chronograph movement for the new edition of the "Daytona", Rolex's most coveted watch.

The champagne dial with three overlapping sub-dials also contributes to the striking appearance of the watch: the typical design feature of the Zenith El Primero Chronograph.
