In skeletonising the 3mm-thin movement of its new Classique Tourbillon Extra-Plat Squelette 5395, Breguet demonstrates its technical and artistic skill to stunning effect.

There are objects whose intrinsic quality is a source of true wonder. The new Breguet Classique Tourbillon Extra-Plat Squelette 5395 is undoubtedly one of those. The extreme finesse of its 581 caliber has already propelled Breguet to bold technical feats in its previous creations. The design of the tourbillon in particular had to be entirely rethought, which led to the creation of a unique architecture. Now the House of Breguet is going even further, removing almost 50 per cent of the material from this movement, without compromising the build. This skeleton design, within an 18-karat gold caliber that literally plays with the limits of what is possible, highlights the true craftsmanship of Breguet watchmakers. Engraving, engine-turning, and anglage add to this to create something truly outstanding.

The extra-thin 581 caliber is a masterpiece of watchmaking. With a thickness of three millimeters, it is one of the finest self-winding tourbillon movements in the world. A feat of technical craftsmanship that required a series of often complex adjustments. For instance, the rotor was placed on the periphery of the plate, saving on thickness while at the same time preserving a clear view of the mechanism. The tourbillon, for its part, has benefited from a complete redesign. The titanium carriage engages directly with the wheel train, not via the intermediary of a pinion at its base, and, what’s more, the silicon escapement has been given a distinct angled shape, something that considerably saves on space. A very unique structure, of which Breguet is the only series manufacturer.
