Titanium, Automatic, Black
Novelties
Limited edition 88 pcs.

Exclusive partnership with Pirelli: world pioneer in technical and industrial innovations and sole supplier of premium tyres for the world’s flagship motorsport competitions.

 

Playing with the famous color codes of Pirelli, the surprise comes from the strap featuring rubber inlays from certified Pirelli winning tyres having competed in real races – and adorned with legendary tread motifs reproducing the profile of a Pirelli Cinturato™ intermediate tyre. The robust 45mm skeleton case with its black DLC titanium elements and contrasting with Pirelli mythical tyre colors touches provides a perfect frame for Calibre RD820SQ. The design and height of the famous Roger Dubuis micro-rotor effectively enhance the spectacular 3D effect favoured by the Manufacture, as does the raised position of the Astral Skeleton. As well as enjoying the key ‘Pirelli’ signature characteristics linking their high-octane timepieces with a landmark motorsports victory, the production of this timepiece is limited to 88 units.

About Complication

An automatic timepiece is a mechanical watch set with either an oscillating mass or a micro-rotor which, thanks to the natural wrist movement winds itself mechanically. Therefore, if worn everyday, the timepiece doesn’t need hand winding. 

A manual timepiece is a mechanical watch that needs to be hand-wound to function. The several mouvements have a “power reserve” that determine the length of time the watch is able to function with its full wound capacity. Especially appreciated from specialist of “Haute Horlogerie”.

A tourbillon is an addition to the mechanics of a watch escapement. In a tourbillon the escapement and balance wheel are mounted in a rotating cage, in order to negate the effects of gravity when the timepiece (thus the escapement) is stuck in a certain position. 

A masterpiece from Roger Dubuis. The achievement of 7 years of research and 40 people included in the production process of the watch. A timepiece working with 4 balance sprung and 5 differentials, for an ultimate precision. A watchmaking achievement that looks for the untouched territories of mechanical accuracy. 

The minute repeater is a timepiece that once mechanically pushed, rings the hours, quarters and minutes of the watch. It is an historic complication that is known for the mechanical achievement of making a mechanical timepiece ring.
