Breguet’s Classique Phase de Lune 7787 is a poetic expression of horology, balancing technical ingenuity with refined artistry. Its Grand Feu black enamel dial is highlighted by powdered silver Breguet numerals, a power-reserve display, and a moon-phase crafted from hammered gold for a lifelike celestial impression. The Maison’s secret signature and meticulous enamelling underscore centuries of tradition, while modern innovations such as a silicon balance spring and lever escapement guarantee precision and resilience.
The automatic calibre 591DRL, finely decorated with a hand-engraved rhodium-plated gold oscillating weight, completes this union of heritage and innovation.
