Clean Factory production applies additional quality controls at the case finishing, dial printing, and movement regulation stages — controls that most replica production skips entirely. The Roger Dubuis King series hollow double flying tourbillon is sourced at Clean specification, and the result is a superclone that performs and presents itself at the standard informed buyers expect from this tier.

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 Clean Factory standard applies most visibly in the bracelet — where link tolerances, clasp resistance, and surface finishing either hold up or fall apart quickly in regular use. On a Clean specification build these details are consistent throughout, not just in factory photography.
