The new GyroDial ZERO retraces the origins of the creation of BYRNE Watch brand.

Presented in two versions (Rhodium Silver and Rhodium Black), this new model is offering a dimension that is distinctly different to the original BYRNE GyroDial watch unveiled last summer in Geneva.


Developed and patented by John Byrne, GyroDial is an innovative mechanical watch whose dial can change moods every day. At midnight or noon, or on demand, the four cuboids that display the cardinal indexes on the dial rotate instantaneously, jumping one stop to reveal another face.

Thanks to an exposed design devoid of a dial, the new GyroDial ZERO model offers an uninterrupted view of its patented movement, including the innovative cardinal marker animation mechanism.


The components are revealed in multiple shades of gray. Bridges, screws, plate, cardinal marker cuboids are finished in Rhodium Silver or Rhodium Black. The GyroDial ZERO starts from the essence, offering the wearer the full vision of the beautiful mechanism.


True to its foundational concept, the watch changes its dial every day, at midnight or noon, or on demand, with its four indexes at 3, 6, 9 and 12 o’clock altering their face – fluid and fast.

For the GyroDial ZERO, the Caliber 5555 has been entirely redesigned. With its long, lithe curves of titanium, the ‘movement dial’ and its hand-grained finishes presents a modern, sleek aesthetic.

The minute track is directly engraved on the plate and treated with SuperLuminova™ to make it perfectly legible.


Situated at the cardinal points of the dial, the four rotating cuboids and their permutations are even more evident and enlarged. They sport a tone-on-tone rhodium treatment that is subtly different from the plate to emphasize the architectural traits of the whole, creating an airy and elegant contrast between the various elements.

The GyroDial ZERO brings a singular, modern, industrial design dimension to the original concept.

Made of grade 5 titanium, the new case has been redesigned, cut on its sides, slimmed and profiled to the furthest extent possible. The bezel, now sandblasted, like the base plate, offers a homogeneous appearance in shades of dark metallic gray, with a sleek, industrial style. Pushing the concept to the limit, the brand name fades away for an even purer design.
