The Colossal has no historical precedent. It’s a watchmaking Everest that cannot be climbed without serious levels of commitment. Stylists, Designers, and Master Watchmakers have been working towards this end for years. A great deal of care has gone into creating every one of the aspects you’ll be learning about here.

For one thing, it marks an important anniversary – the firm’s twentieth: twenty years of complete independence, creative freedom, and Hysek’s constant pushing back of aesthetic and technical frontiers.

Not only that, it’s also the tenth anniversary of another piece that made an impact in its day: the Colosso, a high-flying feat of watchmaking.

As a major Grande Complication piece boasting unprecedented technology – the most ambitious undertaken by the manufacture in over ten years, featuring over 1,000 components. It took over three years to develop the HW80 caliber – and it takes 240 hours of work just to assemble it.
In addition, it embodies a disruptive watchmaking vision, bringing together three concepts: Jumping Hours, a Jumping Perpetual Calendar, and a 3D Moon Phase.
