Roger Dubuis launches premium 45mm Excalibur Spider Flyback chronograph, limited to 88 pieces

Roger Dubuis has introduced a new, limited Excalibur Spider Flyback Chronograph in 18K pink gold - a 45 mm open‑worked statement piece capped at 88 units. The model carries the internal reference DBEX1138 (also cited as RDDBEX1138) and is in line with the brand’s "skeletonized to the extreme" design brief, where the case, dial furniture and hands are all pared back to reveal as much of the mechanism as possible.

The watch uses a pink‑gold case with lacquered markings and a sapphire crystal on both sides, each treated with anti‑reflective coating. A matching pink‑gold crown with a lacquered ring follows the color theme. Despite the open architecture, water resistance is rated at 10 bar (100 meters), which is higher than many display‑caseback chronographs.

Up front, the dial is essentially a multi‑layered display. A black lower flange carries the printed minute track and text, while a pink‑gold coated upper flange frames the movement. Screw‑style hour markers are rhodium plated and filled with Super‑LumiNova. A tachymeter scale sits on the rehaut (raised inner ring on the watch case). The hands are intentionally bold and luminous to stand out against the busy mechanical backdrop.

As the name suggests, this is a flyback chronograph. This means chronograph timing can be restarted with a single press without stopping and resetting first. The movement is automatic and on full display, with modern bridges, visible gear train and a deep, three‑dimensional layout seen in the brand's other watches as well.

Owners get an interchangeable black rubber strap with a black rubber inlay, and both the strap and clasp use the maison’s Quick Release System, meaning no tools are required for swaps. The clasp is a triple‑folding unit with titanium blades and an 18K pink‑gold cover to match the case.

Pricing and availability aren't present on the brand website as of writing, but as per aBlogtoWatch, the Excalibur Spider Flyback Chronograph has an MSRP of $135,000.
