WatchProfessor’s take – Double tourbillon is rare in the industry, not only is it more challenging to produce but also the actual benefits of a double tourbillon diminishes especially on a wristwatch.  So why make such a device when it costs so much more?  Its all about the spirit of accuracy.  Brands uses the Tourbillon to demonstrate their craftsmanship and finishings, but coming from Breguet -being the inventor of the Tourbillon, its especially special.
