The idea of high-frequency precision through frequencies of light and colour was first brought to life with the DEFY 21 Ultraviolet in 2020, which established a new design code for the DEFY 21 that ZENITH is now fully expressing with the DEFY 21 Ultra Colour box set.
Consisting of eight different iterations of the DEFY 21 and limited to only eight box sets, the Ultra Colour pieces are all crafted in entirely matte finished lightweight titanium, allowing the chromatics from within to shine through. The bridges as well as the oscillating rotor of the eight Ultra Colour pieces are monochromatically finished in eight different tones: Black, blue, violet, orange, pink, green, turquoise and khaki.
Visible through the dial as well as the sapphire case back, one can admire the singular El Primero 21 automatic high-frequency 1/100th of a second chronograph that’s at the peak of performance and precision, featuring two independent regulating organs and gear trains for the timekeeping and chronograph functions, operating at frequencies of 5Hz (36’000 VpH) and 50Hz (360’000 VpH), respectively.
The DEFY 21 Ultra Colour box set is made as a very limited edition of only 8 examples and is available exclusively from ZENITH physical and online boutiques around the world.
