Historical significance
Roger Dubuis Excalibur Spider 44 mm Skeletonised Quartz sits within Roger Dubuis's Excalibur Spider line, introduced in 2002. It carries the house codes established since 1995 — quartz tpt case, skeletonised dial and in-house manual-winding, hand-finished — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The movement's bridges are decorated even where they will never be seen once the watch is cased.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Roger Dubuis has spent more than 31 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Excalibur, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Roger Dubuis & Carlos Dias established Roger Dubuis in 1995, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Roger Dubuis calibre produced today.
