One watch, four appearances offered to you, without anything to do, every morning. Roman numerals, Arabic numerals, invisible dial or Sport dial with numbers inspired by sports jerseys enhanced with SuperLuminova. Thanks to its custom-made movement, Byrne invents the watch whose dial changes mood every day. Every night at midnight, or on demand, the four main indexes of the GyroDial dial change, carried by rotating cubes, with an instantaneous jump, which are flush with the surface of the dial. The caliber 5555, was entirely designed, developed and manufactured in Switzerland for the GyroDial Sport. With its long, supple curves made of titanium, the dial with its hand-stretched finish presents a contemporary and very racy aesthetic.
