For its new Classique Tourbillon Extra-Plat Squelette 5395, Breguet has opted for an extra-thin three-millimeter thick skeleton design for its tourbillon movement. An undertaking that is as much technical as it is artistic with emphasis on craftsmanship, of which the watchmaker is at the forefront.
