There are two versions of the Roger Dubuis Excalibur Spider Flying Tourbillon: one with its bezel marked from 0 to 60, and a jewellery model where its bezel is set with diamonds.
Do pay a little more attention on the diamond-set version of the Excalibur Spider Skeleton Flying Tourbillon which has 60 baguette-cut diamonds on the bezel.

This is no ordinary setting because the diamonds of approximately 2.24 carats are set on a rubber moulding over the metal bezel.
Yes, that is right, the diamonds are set on rubber. Two years of research were required and it was undertaken by Pascal Vincent Vaucher, a gem-setting specialist based in Geneva. The ability to set precious stones on rubber resulted in the registration of the “Soft Stones in the Sky” patent.

“Just for the setting, it took two years. It was a complex process to find the best rubber and the optimal thickness. We chose rubber because of its deep, dark colour. We have an interest in contrast and using rubber allowed us to have a dark, spectacular effect. This watch is a haute couture timepiece,” declares Gregory Bruttin, director of movement development at Roger Dubuis.
There is a reason why this Roger Dubuis Excalibur Spider Skeleton Flying Tourbillon is part of its Astral Skeleton collection. Notice the star symbol on the case back? This symbol is also found on the dial side. Photo: © TANG Portfolio. Elfa / Timmy. 2015 Salon International de la Haute Horlogerie.
