Excalibur Sunrise Double Tourbillon by Roger Dubuis

EDITOR'S REVIEW

• The Excalibur Sunrise Double Tourbillon by Roger Dubuis was presented at Watches & Wonders 2024
• It has put four balances on a watch and rendered in three dimensions King Arthur and his fabled knights on a dial and now it has decided to double up on its tourbillons. Flying ones to be exact
• The real skill with this watch – aside from the multi-layered skeleton dial, the 108 specifically chosen red garnets, orange spessartites, and yellow sapphires that are gradated to resembles a sunrise, and the 17 different hand finishing techniques that earned it the Poinçon de Genève seal – is the regulating differential
• This clever link between the two tourbillons twins them so that the faster tourbillon is able to transmit more energy into the watch’s power source to balance the energy supply of the slower one so the power going into the watch is an average of the two. It’s a remarkable feat of engineering but nothing out of the ordinary for Roger Dubuis
