Breguet Héritage Tourbillon 5497

Unveiled at Baselworld 2008, this Breguet Héritage watch with a tonneau shaped case houses a spectacular tourbillon complication driven by a manually wound movement.

The timepiece boasts a sophisticated design: curved on two axes to fit more than perfectly on the wrist, the case, presents a recurring challenge to Breguet’s watchmaking craftsmen and engineers. The double camber, which demands great technical mastery, also applies to the dial. The basic Breguet calibre 187 has been modified and truncated to meet the requirements of this piece.

The Héritage 5497 watch displays its functions on a silvered gold dial. The chapter ring has been painstakingly cut out and superimposed like delicate lacework on the cambered dial that has been engine-turned by hand.

Made of a single piece, the tracery of Roman numerals subtly hugs the contours and intensifies the architecture of the object. The tourbillon bar takes its part in the tableau in the role of the hour marker at 6 o’clock. On the case-back side, the round sapphire crystal allows the view of tourbillon mechanism.
