Breguet Heritage Phase de Lune

The Heritage Phase de Lune 8860bb/11/bb0 embodies Breguet's classical design philosophy through its polished 18kt white gold case, distinguished by the manufacture's signature fluted edge and ergonomically curved profile for optimal wrist comfort. The mother-of-pearl dial center showcases engraved hour segmentation and intricate "flinque alterne" sunburst guilloche work, framed by a domed silver chapter ring with printed minute track. The frosted silver outer rim features blue-rimmed, silver-filled stylized Roman numerals, while blued steel Breguet-style hands provide refined contrast against the luminous dial surface. A moonphase aperture with rose gold gilt moon positioned at the upper right corner adds functional elegance and celestial artistry. The caliber 586L movement operates at 21,600 vph with 38 jewels and a silicon balance spring, delivering 36 to 40 hours of power reserve. This harmonious composition of precious materials, hand-finished dial work, and mechanical precision exemplifies Breguet's enduring commitment to horological excellence and classical aesthetic refinement.
