Created exclusively for TimeForArt 2026, the Zenith Defy Chronograph USM – TimeForArt Unique Piece (Ref. 03.A780.400-T/01.M3642) features a 37 mm stainless-steel case paired with USM's modular design concept. The mirror-finished dial is vibrant, showcasing accents of blue, green, yellow, and orange. This timepiece proudly bears the inscription "Zenith x USM Modular Furniture." At its heart lies the automatic El Primero 400, a chronograph with a column-wheel mechanism that operates at an impressive 36,000 vibrations per hour (5 Hz) and provides a power reserve lasting 55 hours. The watch is elegantly complemented by a stainless-steel ladder bracelet and a matching clasp. Additionally, a unique furniture piece from USM Haller accompanies this watch, tailored for the project with a dedicated storage system and colored panels that echo the collaborative spirit. This partnership reflects the shared design heritage of both companies, as USM patented its Haller modular system in 1965, while Zenith launched the Defy and El Primero in 1969.
