The Zenith El Primero is arguably the most iconic automatic chronograph movement in the world.
There’s a never-ending debate over whether or not it actually beat out Seiko and the Hamilton-Breitling-Heuer-Dubois Dépraz consortium for the title of the world’s first automatic chronograph, but Zenith’s movement is undoubtedly the most famous, timeless and acclaimed of the three.
There have been countless applications of the El Primero since its 1969 debut, but I’m not sure if any have been as radical as the brand’s outrageous new chronograph, the Defy Extreme Chroma.

The Defy Extreme Chroma combines two of Zenith’s more out-there design templates — the Defy Extreme model and the Chroma color treatment — into one maximalist chronograph to rule them all.

The Defy Extreme is the brand’s biggest and boldest sports watch line, featuring a sharp-angled octagonal case measuring a whopping 45mm across, a dodecagonal bezel, a robust 200m of water resistance, an oversized screw-down crown flanked by crown guards with integrated pushers, and an integrated bracelet design. It stands out as a hyper-modern sports watch in a catalog filled with modern sports watches.
