Originally launched at SIHH 2015 Roger Dubuis’ Excalibur Automatic Skeleton, currently offered in pink gold (photo below) or black titanium was Roger Dubuis’ first non-tourbillon skeleton timepiece. For SIHH 2016 they will launch a new version in a high-tech composite material called carbon fibre sheet moulding compound/ composite (SMC).
SMC is a lightweight and hard ready-to-mould composite material manufactured by dispersing long strands of chopped fibre (e.g. glass or carbon fibres) on a bath of resin. The carbon fibre/ resin is compressed at extremely high temperatures. The longer fibres in SMC mean in better strength properties compared to standard bulk moulding compound (BMC).
At 42 mm the new carbon compound case will have the same diametre as the existing Excalibur Automatic Skeleton but at 12.14mm will be slightly thicker (versus 11.44mm). The dial will have a black flange and contrasting red minute-circle.
Inside is the same automatic skeleton Caliber RD820SQ (as per the photo) with a micro-rotor and plate and bridges with a charcoal grey rhodium-plated finish with a circular-grained decoration. Power reserve is sixty hours.
The Excalibur Automatic Skeleton Carbon will come on a black alligator leather/ rubber strap with a black DLC titanium adjustable folding clasp.
