Breguet Classique Tourbillon Extra-Plat Anniversaire Rose Gold — Silver Dial Limited Edition | Ref. 5365BR/15/9WU

Issued to commemorate a singular milestone in the history of precision timekeeping, the Classique Tourbillon Extra-Plat Anniversaire Ref. 5365BR/15/9WU is limited to just 35 pieces worldwide — a number that carries its own eloquence in an era of mass-produced luxury. The reference celebrates the 215th anniversary of Breguet's tourbillon patent, and everything about its construction reflects that commemorative gravity. The 41 mm rose gold case, measuring a breathtaking 7.08 mm in total thickness, makes it one of the flattest tourbillon wristwatches ever produced.

The silver dial is a masterstroke of disciplined beauty. Guilloché engraving, executed by hand on traditional rose-engine lathes that trace their lineage to the same workshops Abraham-Louis equipped in the 1780s, covers the surface in geometric precision. Breguet blued-steel hands sweep above the engraved field, and the flying tourbillon — positioned at six o'clock and seemingly suspended in mid-air without a bridge above it — performs its one-minute rotation in full view. The calibre 581, a self-winding movement developed specifically for this reference, achieves approximately 80 hours of power reserve while maintaining the case's extraordinary slimness.

A brown leather strap, hand-stitched in the ateliers of the finest tanners, completes the composition with understated warmth that flatters the rose gold perfectly. At $136,240, the 5365BR/15/9WU demands to be understood not as a watch purchased but as a horological document acquired — a numbered artefact marking the precise point where history and the avant-garde of mechanical watchmaking converge.
