In 1969, Zenith launched El Primero, the first ever fully integrated automatic column-wheel chronograph movement, enabling 1/10th of a second precision. Half a century later, Zenith once again defied tradition and pushed all existing boundaries, leading us into the world of 1/100th of a second accuracy. A legend reborn, the Zenith DEFY EL PRIMERO 21 is the shining 21st century symbol of a new future for a brand with a truly unique guiding star. And now, the already iconic chronograph is available in a bold mix of black and blue tones as an exclusive limited edition of 250 pieces, available solely at Zenith boutiques around the world.

With a lustrous Midnight Black ceramic case providing a perfect complement to its open high-frequency chronograph calibre, the DEFY El Primero 21 Boutique Edition features an enticing play of tones in black and blue. Like the colour of the cutting-edge DEFY Inventor’s open dial as well as the chronograph register of some of the earliest El Primero chronographs, the DEFY El Primero 21 Boutique Edition’s movement bridges and rotor are finished in an electric “Zenith Blue” colour. Sleek ruthenium-plated hour-markers and hands filled with SuperLumiNova add volume to the complex openworked dial featuring a chronograph power-reserve indication at 12 o'clock, hours and minutes in the centre, small seconds at 9 o'clock, black 60-second counter at 6 o'clock and distinctive blue 30-minute counter at 3 o'clock. Making the DEFY El Primero 21 even more versatile, the Boutique Edition comes with three straps: A black alligator strap with rubber backing and blue stitching, a black rubber strap with a “cordura” effect and blue stitching, and a textured blue rubber strap.
