Gyro Dial - Blue Number 5

One watch, four looks. With its made-to-measure movement, Byrne has invented the evolutionary watch.

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 aestheti
