Summary

- Its 77F1 caliber offers instant dual-time, date-jump and day/night functions
Breguet’s Marine Hora Mundi 5555 marks the fifth chapter in the Maison’s 250th-anniversary celebration. Limited to just 50 pieces, this exquisite timepiece is offered for the first time in warm Breguet gold.
Drawing on NASA’s evocative “Black Marble” imagery, the watch celebrates a nocturnal vision of Earth in motion, where glowing city lights stand out against a deep-blue backdrop. Designed for modern travelers, it allows each owner to personalize the city disc for any of the 24 time zones, reinforcing the model’s bespoke spirit.
At its heart lies a two-level dial construction that fuses traditional guilloché with cutting-edge artistry. The lower layer is a solid gold plate, hand-turned with meridians and parallels and graduated from sky-blue to navy to mimic sea meeting sky. Above it, a translucent sapphire disk carries three phases of hand-painted miniature enamel: reverse-engraved continents fired in grand feu, floating clouds on the crystal’s surface, and phosphorescent enamel dots marking city lights. This complex, patented enamel work ensures that no two dials – and no two nocturnal cloudscapes – are ever alike.
Encased in a 43.9 mm Marine case, the Hora Mundi 5555 houses Breguet’s caliber 77F1 — a robust, patent-protected movement introduced in 2022. Its mechanical memory enables instantaneous switching between home and local time with a pusher at 8 o’clock, while automatic date jumps and a day/night indicator keep both zones in sync. Through the sapphire caseback, the gold-toned oscillating weight and 250th-anniversary “Quai de l’Horloge” guilloché framing pay tribute to Abraham-Louis Breguet’s naval heritage, blending technical mastery with centuries-old savoir-faire.
