Zenith DEFY Chronograph USM Collection Box Set: 4 watches

When Watchmaking Meets Swiss Design

Born from the collaboration between Zenith and USM Modular Furniture, the DEFY Chronograph USM capsule reimagines the creative spirit of the 1960s. For the first time, the legendary El Primero calibre is housed in a Defy Revival case, resulting in a unique creation offered in four emblematic USM colors: USM Green, Pure Orange, Golden Yellow, and Gentian Blue.

An Exceptional Set

Available exclusively and produced in extremely limited numbers, the DEFY Chronograph USM set brings together the four variations of this one-of-a-kind capsule. Each watch is limited to just 60 pieces worldwide and embodies the meeting of Swiss watchmaking precision with the geometric rigor of industrial design.

Presented in a specially designed USM Haller cabinet, this set is far more than a case: it is a true functional design module, conceived to hold and showcase the four watches while seamlessly integrating into a contemporary environment.

The USM Spirit on the Wrist

Each dial color – Gentian Blue, Golden Yellow, Pure Orange, and USM Green – reflects a historic shade from USM furniture. The square grooved indexes, silver-toned azuré subdials, and chronograph seconds hand tipped with a luminous USM sphere create a direct link with the visual language of modular furniture, while asserting a strong horological identity.

A Legendary Movement

All pieces are powered by the El Primero 400 calibre, a direct descendant of the 1969 movement, still celebrated for its precision and high frequency (36,000 vph – 5 Hz). With its column wheel, horizontal clutch, and 55-hour power reserve, it remains an absolute benchmark among mechanical chronographs.

A Manifesto of Swiss Creativity

The DEFY Chronograph USM set exemplifies the perfect union of two Swiss legacies: Zenith’s watchmaking mastery and USM’s timeless design. A true manifesto, it celebrates the creative freedom of the 1960s while offering a contemporary reinterpretation, where every detail – from the octagonal case to the luminous USM sphere – tells a story.
