Pre-SIHH 2016: Roger Dubuis - Excalibur Automatic Skeleton Carbon

| No comment
First presented at the SIHH 2015, the Excalibur Automatic Skeleton was Roger Dubuis’ first non-tourbillon skeleton timepiece and was equipped with its first skeletonized automatic movement.

In 2016, Roger Dubuis is now presenting the Excalibur Automatic Skeleton Carbon, featuring a new case that was crafted using a high-tech composite known as carbon fibre sheet moulding compound (SMC) which is twice as light and twice as hard as steel.


A lightweight material widely used in the aerospace industry, sheet moulding compound (SMC)
enables excellent part reproducibility and, above all, the possibility of creating components with complex shapes and integrated functions. SMC is produced by compressing carbon fibres with resin and steel moulded at extremely high temperatures, which is then reworked and compounded with resin.


The resulting technical look is ideal for an avant-garde sporty timepiece. The 42 mm x 12.14 mm case frames a skeleton dial with black flange, red minute-circle, white gold appliques and skeleton hands in gold.

The 4Hz (28,800 vph) RD820SQ automatic skeleton calibre is equipped with an openworked version
of the signature Roger Dubuis micro-rotor introduced in 2005 and delivering winding
power equivalent to that of a central rotor. Guaranteed power reserve is 60 hours.

Each of the 167 movement components is meticulously hand-finished on all faces in accordance
with the stringent requirements of the Poinçon de Genève certification.

The Roger Dubuis Excalibur Automatic Skeleton Carbon is complemented by an alligator leather/rubber strap. rogerdubuis.com
