Dual Time GMT Resonance First Edition

At the heart of this horological experiment is our ARF22 calibre. It is the 18th in-house movement born from our manufacture, engineered, designed and built entirely by us. Like the 17 movements before it, it’s a true in-house affair. It features two balances that work in resonance, allowing their oscillations to synchronise and mutually regulate each other.

With 231 components meticulously arranged and orchestrated to perform at 25,200 vibrations per hour, the ARF22 delivers 42 hours of power reserve. The GMT function of the timepiece uses two independent displays, each with its own day/night indicator. And thanks to independently adjustable hour and minute hands, you can set time zones that deviate from GMT by fractions of an hour. This feature makes the Dual Time GMT Resonance First Edition truly global—whether you are tracking time in Biel, New York or New Delhi.

But the essence of this timepiece is found in its mechanical heart. There, our patented clutch spring ensures that resonance remains stable even during wrist movements—a milestone in the history of horology, elevating timekeeping to both an art form and a science.
