If you had a need for speed, the booth of Roger Dubuis was the place to be during SIHH 2018! Completely dedicated to the partnerships that the brand has with both Lamborghini, as well as Pirelli, it introduced exciting new versions of both the Excalibur Spider Pirelli, as well as the Excalibur Aventador S.
Why do brands include more than one tourbillon to a watch movement? The primary answer to that question is because it makes the watch more accurate. Originally developed to limit/eliminate the influence of gravity, the tourbillon is still the most efficient in a pocket watch, because that remains mostly in the same position. Their effectiveness in wrist watches is limited, but two (or more) is always better, as a differential can take the average rate of the tourbillons and combine them into a single output, which will, by the law of averages be more precise. These are some of our favorite watches with double tourbillons!
