“Roger Dubuis Excalibur Spider Skeleton Flying Tourbillon” can refer to more than one watch. The two references identified on Roger Dubuis’s official site are the 45 mm titanium RDDBEX0545 and the 45 mm carbon RDDBEX0752. Both are manual-winding watches rated to 5 bar, but they use different calibres and have different power reserves: 60 hours for the titanium model and 90 hours for the carbon model.
Which Excalibur Spider reference are you looking at?
Check the reference number before relying on a specification. Roger Dubuis lists the titanium RDDBEX0545 and carbon RDDBEX0752 as Excalibur Spider Skeleton Flying Monotourbillon watches. Their similar names and shared 45 mm case size can make them easy to confuse, but their movements and reserves are not the same.
| Reference | Case | Movement | Power reserve | Water resistance |
|---|---|---|---|---|
| RDDBEX0545 | Titanium skeleton case | RD505SQ, manual winding | 60 hours | 5 bar (50 m) |
| RDDBEX0752 | Carbon case with titanium container and rubber inlays | RD509SQ, manual winding | 90 hours | 5 bar (50 m) |
These specifications are listed by Roger Dubuis for the RDDBEX0545 and RDDBEX0752. Both pages give the watches hour and minute indications. The carbon model’s listed 90-hour reserve is 30 hours longer than the titanium model’s 60-hour reserve.
What distinguishes the titanium RDDBEX0545?
Roger Dubuis describes RDDBEX0545 as a 45 mm titanium skeleton watch with the RD505SQ calibre. It is manually wound, displays hours and minutes, and is rated to 5 bar (50 m). Its listed power reserve is 60 hours. These are specifications for this reference, not a universal set of specifications for every Excalibur Spider Skeleton Flying Tourbillon.

What distinguishes the carbon RDDBEX0752?
RDDBEX0752 has a 45 mm carbon case, with a titanium container and rubber inlays, according to Roger Dubuis. Its manually wound RD509SQ calibre provides hour and minute indications and a listed 90-hour power reserve. The official page also rates it to 5 bar (50 m).
Roger Dubuis says of this model: “The flying tourbillon requires the expertise of the highly-skilled watchmakers of Roger Dubuis and is manufactured in our workshop in Geneva.” This is the manufacturer’s description, rather than an independent assessment.

Is every RD505SQ version the same?
No. Fondation Haute Horlogerie describes an RD505SQ version with a 45 mm titanium case, 50 m water resistance, a 60-hour reserve and a limited edition of 88. The foundation’s description specifies a diamond-set rubber bezel for that special edition; that detail should not be assumed to apply to every Excalibur Spider or to every RD505SQ variant. See the Fondation Haute Horlogerie listing for that edition.
How to identify the right watch before buying
- Find the reference number. Look for RDDBEX0545 or RDDBEX0752 in the listing or ask the seller to confirm it. A model-family name alone does not establish which specification set applies.
- Match the reference to the movement and reserve. RDDBEX0545 is listed with RD505SQ and 60 hours; RDDBEX0752 is listed with RD509SQ and 90 hours.
- Confirm edition-specific details. Do not assume a special-edition bezel, limited production number or other feature belongs to the standard version unless the exact reference and edition are documented.
- Verify availability and seller details directly. Retailer pages or collection listings do not by themselves confirm current stock of either reference. Ask for the exact reference and verify the seller before purchase.
Availability and pricing
Current stock and pricing for RDDBEX0545 and RDDBEX0752 are not established by the official product specifications above. Retailer pages surfaced for a Cellini listing and a Bucherer Excalibur collection, but neither confirms current inventory of these exact references. Check directly with a retailer and confirm the reference before treating a listing as an offer for the watch you want.
