Breguet Marine Hora Mundi 5555

To mark its monumental 250th anniversary, Breguet unveils the Marine Hora Mundi 5555, a technically advanced traveller’s watch that blends horological innovation with artisanal beauty. Building on its patented instant time zone-jump mechanism, this latest iteration introduces a dual-layered dial with hand-painted continents, phosphorescent city lights, and a refined Breguet gold case. Limited to just 50 numbered pieces, it is both a tribute to the brand’s legacy and a celebration of contemporary haute horlogerie.
The case of the Marine Hora Mundi 5555 is crafted from 18k Breguet gold, a warm, rich alloy inspired by the tones used by 18th-century watchmakers. Measuring 43.9mm in diameter with a thickness of 13.8mm, it features a harmonious combination of satin-brushed and polished surfaces. Signature details of the Marine line remain intact, including the fluted caseband and robust lugs.Turning the watch over reveals a beautifully decorated caseback adorned with a special 250th-anniversary guilloché motif known as Quai de l’Horloge, referencing Breguet’s historic Parisian headquarters. A sapphire crystal exhibition window offers a view of the in-house calibre 77F1 and its intricately finished components, including the bespoke Breguet gold rotor. Each of the 50 examples is individually numbered and hand-engraved along the caseback’s outer edge.It comes equipped with a crown at 8 o’clock that doubles as a selector for time zone changes. Plus integrated crown guards and a uniquely polished central lug attachment designed for this special edition. All topped by a domed sapphire crystal with anti-reflective coating. Water-resistance can reach up to 100 meters (330 feet).
The dial of the Marine Hora Mundi 5555 is a multi-layered masterpiece, designed to evoke the curvature and depth of Earth as seen from space. Its base is crafted from solid gold and features hand-executed guilloché engraving that traces meridians and parallels across a horizontal gradient, sky blue at the center transitioning to deep navy at the periphery. This lower dial forms a rich, textured foundation reminiscent of NASA’s “Black Marble” imagery.
Above it floats a translucent sapphire crystal disk, meticulously hand-painted on both sides. The reverse side displays the continents in Grand Feu enamel with precision pad-printed contours, while the upper side is decorated with enamel-painted clouds. A patent-pending phosphorescent enamel technique is used to illuminate city lights at night, creating a magical nighttime glow that is entirely unique to Breguet’s craftsmanship.Framing this tableau are applied Roman numerals in blued gold, accompanied by a matching Breguet gold hour and minute hand set in the brand’s iconic pomme (apple-shaped) style. All elements are treated with light grey Super-LumiNova for optimal legibility in low-light conditions, subtly enhancing functionality without distracting from the artistry.

The “Breguet Marine Hora Mundi 5555” (Ref#: 5555BH/YS/9WV) is powered by the in-house self-winding mechanical movement, caliber 77F1 with 40 jewels, 384 components, and 28,800 vph. It comes equipped with patent modules for instant time zone jump and mechanical memory. Power reserve can last up to 55 hours, when fully wound.
Mounted on this watch is a navy blue alligator leather strap, secured by an 18k Breguet gold triple-folding clasp. It complements the marine inspiration of the timepiece while offering a luxurious and secure fit on the wrist. The package also includes an additional rubber strap, housed in a red Moroccan leather case, enhancing both versatility and exclusivity.
The Breguet Marine Hora Mundi 5555 is a limited edition of just 50 individually numbered pieces, each engraved on the caseback from 1/50 to 50/50. In celebration of the brand’s 250th anniversary, this exclusive release offers collectors the opportunity to personalize the city disc, reinforcing the watch’s bespoke character and commemorative significance.
