Every Roger Dubuis movement bears the Geneva Seal. A few years ago that did not mean much, for despite having the seal Roger Dubuis watches often suffered from quality control issues. Now that has changed. Under Richemont ownership management has made sure that the spirit, and not just the letter, of the Geneva Seal is adhered to.
Fine finishing at Roger Dubuis is performed assembly line style, with each step of finishing being broken down into smaller steps, giving rise to extreme specialisation amongst the craftsmen who do the finishing. A lever for instance, is finished in multiple steps: the faces and various edges are each finished by different craftsmen along the line.

Although parts are worked on in an assembly line style, they are still laboriously finished by hand. Despite their sometimes distracting aesthetics, Roger Dubuis movements are all very well finished, especially compared to its competitors in the segment of oversized, high-end watches.

As a personal observation, though I regard the finishing of Roger Dubuis movements highly, some of the movement parts can be revised to better show off the high level of finish. Certain aspects of a few calibres can be made more elaborate, like the arms of tourbillon cage for instance which can be less flat. No doubt they were designed in this way for efficient manufacturing and assembly but they can be improved.
