Zenith Adds Bracelets, Rose Gold, And Diamonds To The Defy El Primero 21 Collection

It was one of the highlights of last year’s Baselworld: the Zenith Defy El Primero 21. While the El Primero itself has already set the standard of its chronograph to 5Hz/36.000 bpm in 1969, allowing you to measure with a 1/10th of a second accuracy, the El Primero 21 exceeds this tenfold. Running at a staggering 50Hz, the chronograph measures up to 1/100th of a second, and does so with a central seconds hand, which makes this accomplishment all the more tangible.
