Full-Cataloguing
Created as a unique piece for TimeForArt 2026, the ZENITH DEFY Chronograph USM brings together two Swiss names whose design histories were shaped by the same period of experimentation in the 1960s.
USM patented its Haller modular furniture system in 1965, while ZENITH introduced the original DEFY and the El Primero calibre in 1969. Both reflected the design language of their time. The present watch is based on the 37 mm stainless-steel DEFY Chronograph USM and is distinguished by a unique mirror-polished dial. The reflective surface is complemented by blue, green, yellow and orange details drawn from USM’s signature colour palette. The watch is powered by the El Primero 400 automatic high-frequency chronograph calibre, operating at 36,000 vibrations per hour (5 Hz).
For TimeForArt, the watch is accompanied by a unique USM Haller furniture piece designed specifically for the project. Featuring a dedicated watch storage system and coloured panels referencing the collaboration, it was conceived together with the watch and forms part of the lot. It will be shipped to the buyer by the brand separately after the sale.
The result is a one-of-a-kind set linking ZENITH’s watchmaking heritage with USM’s modular design language, both rooted in the creative and industrial experimentation of the 1960s.
