Zenith unveils Defy 21 Ultra Colour box set

Consisting of eight different iterations of the Defy 21 and limited to only eight box sets, the pieces of the Defy 21 Ultra Colour box set are all crafted entirely in  matte finished lightweight titanium. 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, with cordura-effect rubber straps also made to match. Visible through the dial as well as the sapphire case back is El Primero 21 automatic high-frequency 1/100th of a second chronograph, 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 Ultra Box set is delivered in a bespoke presentation case. Each of the watches is engraved on the case back with a limited edition number out of 8, and each box set will feature watches that are sequentially numbered 1 through 8, rather than having the same number for all eight watches in a single box set.
