The finesse of the new Classique Tourbillon Extra-Plat Squelette’s 581 calibre has already propelled Breguet to bold technical feats in its previous creations. Now the House of Breguet is going even further, removing almost 50 percent of the material from this movement, without compromising the build. This skeleton design, within an 18-karat gold calibre that literally plays with the limits of what is possible, highlights the true craftsmanship of Breguet watchmakers.
An Extra-Thin movement
The extra-thin 581 calibre is a masterpiece of watchmaking. With a thickness of three millimetres, it is one of the finest self-winding tourbillon movements in the world.
The rotor is 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.
Lightness and transparency
The carriage weighs no more than 0.29 grams in total and is equipped with an outstanding power reserve of 80 hours. This 581 calibre already featured in models 5377 and 5367.
And here, for the first time, it has been incorporated in a fully skeletonised design, a contemporary interpretation of this ancestral technique. The gold plate and bridges have been hollowed out to display the mechanical anatomy of the movement.
A Sophisticated and minimalist design
The Classique Tourbillon Extra-Plat Squelette 5395 sits in a fluted case topped with a domed glass-box revealing the movement. The sapphire dial features applied hour markers in blued gold. The hours chapter is created using galvanic growth and the timer is laser-engraved and filled with blue varnish. This design is rounded off with traditional blued moon-tipped hands and soldered horns in true Breguet style.
