Breguet Unveils One of World’s Thinnest Tourbillons

breguet classiquePre-released at Baselworld 2013, the Breguet Classique tourbillon extra-thin automatic has made a return to the center-stage in a regal platinum façade.

As beautiful as it is ingenious, this exceptionally extra-thin watch is accentuated by one of the most spectacular horological inventions – the tourbillon.

It is distinguished by an off-center tourbillon with a carriage in titanium which formulation is protected by several patents.

The movement of this 5377 itself incorporates a balance spring in silicon – lauded for its anti-magnetic properties – and an escapement made of silicon and anti-magnetic steel.

These technical characteristics enable the new calibre 581DR  fitted into this Classique watch to beat at 4Hz, a high frequency for a tourbillon. Yet, the power reserve is not sacrificed. Thanks to the patented “high-energy” barrel, the reference 5377 provides 90 hours of running time.

To keep the height of the movement down to 3mm in a 7mm thick case, Breguet’s watchmakers have placed the bi-directional platinum winding rotor on the periphery of the movement. This technical prowess makes this automatic tourbillon one of the world’s thinnest.

Stylistically, the dial of this 42mm platinum watch is decorated with four engine-turned patterns which embody a full measure of respect for high watchmaking centuries-old values: 1) a hobnail pattern for the hours and minutes chapter; 2) a barleycorn surround; 3) a straight chevron pattern for the power-reserve indicator at 8:30; 4) cross-hatching to outline each feature. A blue sapphire at the centre of the tourbillon bridge draws the eye down from the hands.

Supremely elegant, this new Classique tourbillon extra-thin automatic is a thoroughbred Breguet subtly combining timeless aesthetic and technological vanguard.
