Zenith Chronomaster El Primero C.01 Limited Edition

This year, to coincide with the 50th Anniversary of the legendary El Primero movement, Zenith has collaborated with Silicon Valley based collector’s club ‘Collective’ to create a unique edition of the Chronomaster El Primero, made available exclusively to the group’s members.

The group is comprised of creatives, executives and makers, many of whom are in tech and live in Silicon Valley (San Francisco Bay Area), Silicon Alley (New York City) and Silicon Beach (Los Angeles). Collective is founded on the idea that as watch collectors, members want a dedicated place to share, enjoy one another’s company and celebrate their love for watchmaking.


As a watch that Collective’s founders, Gabe Reilly and Asher Rapkin have always loved, the El Primero was where the duo wanted to begin. Partnering closely with Zenith’s Switzerland based design team and established Bay Area jeweler Topper Jewelers to create this unique timepiece, the team first focused on the dial.

In Silicon Valley, where simplicity and usability are key elements of quality product design, they wanted to apply that same aesthetic and approach to the C.01. While the structure of the iconic subdials remains true to the original, the approach to their design is wholly unique.

The entire dial has been finished in matte white, with a subtle but highly legible and uniform grey making up all the printing on the dial. In order to ensure maximum balance, the date was removed, and the classic red chronograph hand has been replaced with a unique rhodium plated hand created just for this piece.

To serve a desire to make the watch a tool, utilizing modern design principles to put functionality at the forefront, the 38mm case features alternating satin-brushed and polished surfaces, and unique to this watch, satin-brushed pushers.

The caseback displays the beautiful El Primero movement and features an XX/50 engraving along with a “C.01” engraving celebrating the launch piece of Collective.

Most Chronomasters utilize a leather strap with a deployant buckle, but Collective wanted to ensure that the “tool watch” aesthetic carried through all the way to the strap and the buckle.

Every C.01 will ship on a custom-sourced cordura strap to provide the watch with a more industrial feel.
