Whether it’s vibrantly colourful dials in the 1970s or groundbreaking movements finished with striking tones in its more recent creations, ZENITH has never shied away from exploring chromatics in new and daring ways. 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 open dial features raised chronograph counters matching the grey tone of the case, beneath which vibrant metallic colours are applied in the least expected part of the watch: the movement. 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. The metallic tones shift with the light, enhancing the sense of volume and dynamism of this exceptional vibrant series. The cordura-effect rubber straps are also made to match the colours of the movement.
