What about it

The A3818, known by its nickname 'Cover Girl', has garnered its fame due to being prominently featured on the cover of Manfred Rössler's esteemed book "Zenith: Swiss Watch Manufacture Since 1865".

In 1969, Zenith presented the El Primero movement, the Swiss industry's first integrated automatic chronograph movement vibrating at 5Hz. The movement was housed in two different style cases: a round model designated the A386, and two barrel or tonneau shaped models dubbed the A384 and A385. In 1971, Zenith debuted an execution of the A385 that was destined to become a legend. That watch named the A3818 featured the barrel case and an integrated ladder style bracelet created for Zenith by the most famous bracelet maker of the era, Gay Frères.

The watch showcased a vibrant blue dial adorned with vertical brushing, featuring a distinctive 'shark tooth' racing track encircling its perimeter, along with a combined pulsometer and tachymeter. Its innovative scale allowed for reading one's pulse within 15 beats, seamlessly transitioning into a functional tachymeter. The chronograph seconds hand boasted a small luminous paddle, resulting in the creation of one of the most uniquely stylish sports chronographs in horological history.

El Primero movement

The El Primero movement stands as an iconic achievement, boasting over 50 years of continuous production. Its inception in 1969 marked the culmination of seven dedicated years by Zenith's craftsmen, driven to craft the inaugural fully integrated automatic chronograph movement. While the easier path would have involved appending a module to a base movement, Zenith pursued a more ambitious vision, laden with additional requisites, thereby intensifying the project's complexity. Foremost among these demands was the pursuit of an elevated beat frequency within the calibre, enabling the chronograph function to impeccably measure time down to 1/10th of a second.

Superman Blue dial

Romain Marietta says, “We decided to make every single indicator on the Superman Blue dial luminous. Yes, that means every one of the marks on the 'shark tooth' scale, every indication in the pulsometer and tachymeter, all the subdials and even the hands on the subdials. Because some of these indexes are so small, it took a lot of trial and error to get this exactly right, but we managed it. If you shine a UV light on the Cover Girl Revival, the effect is amazing as you see this incredible luminous light display.”

Brushed dials offer a unique advantage — they present varied appearances when viewed from different angles and under varying lighting conditions
