Bulgari-Daniel Roth Collection: Tourbillon Lumière Rose Gold

The Tourbillon Lumière, powered by Calibre DR 780, is a superlative horology creation epitomises the ultimate expression of the art of skeleton working. The absolute perfection expressed in this diaphanous watch involved taking full account of the major parameter inherent in this exercise: paring down the movement structure as much as possible, while maintaining its rigidity and load-bearing capacity in order to guarantee its smooth running. This might be viewed as the art of doing more with less.

The goal has been fully met in a feather-light creation of which the brown gold-plated components are clothed in a double-ellipse rose gold case. The plates, bridges and ratchet-wheel are meticulously openworked. Each of the parts is chamfered, hand-drawn and exquisitely chased. A slender satin brushed inner bezel ring, adorned with diamond-polished dots for the hours and minutes, is integrated within the skeleton-work process.

The dial merges into the movement and features a minimum of finely engraved metal serving to mark the hour circle on the front and the power-reserve display on the back. The mainplate is barely 3.48 mm thick, making this model one of the world’s thinnest tourbillon watches. This paragon of transparency is fitted on either side with sapphire crystals featuring an anti-glare treatment designed to guarantee that nothing will impede the crystal-clear vision of its inner beauty, revealing the tourbillon with straight-line lever composed of 82 parts and including a polished bridge.
