The dial of the Classic Fusion Tourbillon Firmament watch is made from osmium crystal. Osmium is considered as being the rarest metal on our planet. Its origins date back to the formation of the Earth and the primitive solar nebula. Metal alloys from the same group –which have a very high melting point – must have formed at depths over 2900 km where the temperature is sufficiently high to melt these elements. Convection movements raised these materials to the surface, almost unchanged since the formation of our planet.

In its compact and crystallised form, it becomes inalterable in air and its brilliance will never fade. Its blueish sparkle is unique amongst metals. And there lies the wonder of osmium crystal dials: osmium crystals vary in size from tenths of a millimetre to just a few millimetres, making osmium in its crystal form one of the greatest new developments in the precious metals market.

Thanks to the research of a team of scientists and researchers based in the Swiss Canton of Valais, osmium is crystallised using a highly sophisticated process; this enables it to reach its melting point (3,033 degrees Celsius), changing its structure and transforming it into osmium crystal.

The case of the Classic Fusion Tourbillon Firmament watch is in polished black ceramic and its diameter is of 45mm. The timepiece features a strap in black alligator stitched onto black rubber with black stitching.
