Zenith Defy 21 Ultraviolet

If all the colours that our eyes can perceive are to be considered as frequencies of visible light, then violet has the highest frequency of them all, beyond which is invisible ultraviolet light. It was only natural to pair this intense, energetic colour with the highest-frequency chronograph in regular production, the DEFY 21.

In past centuries, violet was coveted as the most sought-after colour dye for garments, the production of which was a closely held secret by certain civilizations such as the Phoenicians. Its rarity and compelling beauty made it the stuff of royalty. Today, violet tones portray a sense of daring, confidence and whimsy, from sports cars to bespoke tailoring. Yet in the world of watchmaking, violet remains a rarity.
