Introduction
Arguably one of the most famous chronograph makers in all of horology, Zenith is best-known for their El Primero automatic chronograph movement. From its status as one of the first automatic chronograph movements ever made (depending on who you ask) and the base movement to feature within the second-generation Rolex Daytona, the El Primero is certainly a modern-day icon. Launched in 1969, its incredible hi-beat rate, amazing accuracy and technical prowess ensured that any watch it was inside was one of the best chronographs money could buy. Offered here as a part of the El Primero family we have the ref. 03.0520.4002, which is the “Grande Class” – thanks to its 44mm stainless steel case. Decidedly more casual than most El Primero models, this variant combines an understated design for its case with a black dial that aims to be only as exuberant as required. Boasting a bi-compax dial design with the date at 4:30, this timepiece is wonderfully legible with its hour markers punctuated by applied Arabic indices for the even hours and applied dagger-shaped indices at the odd hours.

TIMING MACHINE READOUT
This reading was taken (crown down) with a ONEOF Accuracy Boutique Edition timing machine at time of cataloging. It is provided as a courtesy only, and shall not be construed as a warranty or guarantee of any kind. Please refer to our terms and conditions of sale for more information.
Condition
Watch is in overall near-mint condition. The steel case shows light signs of wear, with some scratches to the polished bezel and to the backs of the lugs from strap changes. The dial and hands are near mint. It is fitted with a leather strap and a steel pin buckle. Additionally, a Zenith deployant clasp is included. Comes with its box, which shows some degradation to the inner lining.
Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, the exotic skin strap will have to be removed.
Our Perspective
Physically in charge and horologically astute, the Grande Class El Primero is what you reach for when you want a big watch that's packed full of impressive horological engineering.
