Breguet’s Marine Hora Mundi 5555 showcases a two-tiered dial, including a guilloché gold base beneath a sapphire disc adorned with enamel continents and illuminated city lights.

Breguet's Marine Hora Mundi 5555 signifies the fifth installment in the Maison's 250th-anniversary commemoration. This magnificent clock is available for the first time in warm Breguet gold, with a limitation of only 50 pieces.

Utilizing NASA’s striking “Black Marble” photography, the watch commemorates a nighttime perspective of Earth in action, with luminous city lights contrasting against a deep-blue background. Tailored for contemporary travelers, it enables each owner to customize the city disk for any of the 24 time zones, enhancing the model's personalized essence.

At its core is a two-tiered dial design that combines classic guilloché with contemporary creativity. The lower layer consists of a solid gold plate, meticulously crafted with meridians and parallels, and progressed from sky-blue to navy to emulate the horizon where sea meets sky. A translucent sapphire disk features three stages of hand-painted miniature enamel: reverse-engraved continents fired in grand feu, floating clouds on the crystal's surface, and phosphorescent enamel dots indicating city lights. This intricate, patented enamel technique guarantees that each dial, as well as each nocturnal cloudscape, is unique.

The Hora Mundi 5555, enclosed in a 43.9 mm Marine casing, has Breguet’s caliber 77F1 – a durable, patented movement launched in 2022. The mechanical memory facilitates immediate transitions between home and local time via a pusher at 8 o’clock, while automatic date advancements and a day/night indicator provide synchronization of both zones. The sapphire caseback reveals the gold-toned oscillating weight and the 250th-anniversary “Quai de l’Horloge” guilloché, honoring Abraham-Louis Breguet’s maritime legacy while merging technical expertise with centuries-old craftsmanship.
