The Roger Dubuis Excalibur Spider Pirelli Double Flying Tourbillon (Model: R is built to Clean Factory standard — the production tier that watch collectors reference when they want a superclone that holds up under the kind of inspection that standard replicas fail. The finishing is consistent, the movement is regulated, and the case geometry follows the original reference dimensions without the dimensional compromises that lower-tier production accepts.

Movement & Performance
The tourbillon cage is assessed on a Clean Factory build for rotation consistency and visible finishing quality — both the structural execution of the cage itself and the movement architecture beneath it. At Clean specification the tourbillon functions as a genuine mechanical complication rather than a decorative approximation, and the finishing reflects the standard the mechanism demands.
The distinction between Clean Factory and standard replica production is not marketing positioning — it is a measurable difference in case geometry, finishing depth, and movement stability that becomes apparent within the first weeks of regular wear. This piece maintains that standard.
