One watch, four looks. With its made-to-measure movement, Byrne has invented the evolutionary watch. Every evening at midnight, or whenever you choose, there is a changing of the four cardinal indexes on the GyroDial. Arabic numerals, Roman numerals, special characters or designs – each index is displayed on the face of a flush-mounted rotating block; the jump from one display to the next is disconcertingly instantaneous. And because time is what you make of it, Byrne also offers the possibility of customising the faces of each rotating block, as well as the case material. The case, like the calibre 5555, was entirely designed, developed and manufactured in Switzerland for the GyroDial. With its long, supple curves of titanium, the dial and its straight grain satin finish presents a distinctive contemporary and sleek aesthetic.
