Roger Dubuis lists a 90-hour power reserve for this reference. A separate 28-piece edition documented by the Fondation Haute Horlogerie has different movement figures, so its specifications should not be blended with the current product page.
What watch does the name refer to?
Roger Dubuis’s current product listing identifies the Excalibur Spider Carbon 45mm as reference RDDBEX0752. This is a specifications-led overview; the available information does not establish first-hand handling or wear observations.
The brand characterizes the collection as “All watches from this collection are skeletonized to the extreme.” On RDDBEX0752, that open architecture is paired with carbon in both the case and specified movement structures.
RDDBEX0752: the current manufacturer-listed specification
The following figures and construction details are from Roger Dubuis’s RDDBEX0752 product page, accessed in 2026. They are manufacturer specifications, not independent test results.

Carbon continues into the movement
Roger Dubuis specifies multilayer carbon for the RDDBEX0752’s main plate, bridges and tourbillon-carriage upper bridge. That makes the material part of the movement architecture as well as the exterior case and bezel; the listing does not provide a weight figure or comparative test data.
Dial and strap details
The brand describes carbon flanges with transferred text and minute tracks, rhodium-plated screw-like hour markers with SLN in the center, and a hexagonal carbon grill between the plate and bridges. The black rubber strap has a white Rubber Tech inlay and red stitching on its rubber section. A rubber crown with a carbon cover completes the listed exterior details.

Do not confuse it with the 28-piece edition
The Fondation Haute Horlogerie (FHH) describes a separate Excalibur Spider Carbon 28-piece limited edition. Its entry gives a 45mm carbon case, 50m water resistance and a manual RD509SQ flying tourbillon, but lists 179 components and a 70-hour power reserve. It also describes a red strap with a fabric-like high-tech rubber inlay, a carbon movement plate and bridges, a carbon tourbillon upper cage, and a honeycomb-pattern dial.
These numbers are not interchangeable with the current RDDBEX0752 listing’s 198 components and 90 hours. The two sources do not explain whether the difference reflects a movement revision, distinct configurations or an inconsistency. The FHH page’s publication date is not shown, so its figures should remain attached to the specific 28-piece edition described there.

Water resistance and strap interchangeability
What the 5 bar / 50m rating tells you
For RDDBEX0752, Roger Dubuis states water resistance of 5 bar (50m). That is the published rating; it is not, by itself, a manufacturer recommendation for swimming or diving. The cited product page does not establish those activities as suitable uses.
What QRS interchangeability means
Roger Dubuis says the strap and triple-folding titanium-blade clasp are interchangeable through its Quick Release System (QRS). The listing does not identify a verified aftermarket replacement strap or compatible third-party part, so confirm compatibility with the brand or an authorized seller before ordering accessories.
