The ‘MP-09 Tourbillon Bi-Axis 5-Day Power Reserve is entirely designed by Hublot and  takes the iconic Rainbow design and thrusts it into the 21st century. Everything had to be reinvented: the concept, the method, the tools, the materials, and all the associated colour ranges.

To achieve this result, hundreds of coloured inserts had to be created. As the eye spontaneously combines them to recreate a harmonious and natural gradation, the effect is almost an optical illusion.

In reality, Hublot had to develop a complete prism of infinite shades to reproduce the brilliance of gemstones – a first in watchmaking.
