Breguet is celebrating its 250th anniversary in 2025 with a series of five novelties across its collections. After the Classique Souscription 2025, Tradition Seconde Rétrograde 7035, Type XX Chronographe 2075, and Classique Tourbillon Sidéral 7255, the latest to join is the Marine Hora Mundi 5555 - a globetrotter’s watch housing one of the most user-friendly dual-time mechanisms.
Like all the other anniversary editions, the Marine Hora Mundi 5555 is also crafted in Breguet gold, a warm alloy inspired by the 18th-century tone. Measuring 43.9 mm in diameter and 13.8 mm thick, it features the brand’s fluted case middle, polished central attachments, and a caseback decorated with a special “Quai de l’Horloge” guilloché motif created for the anniversary. Despite its complexity, the watch is water-resistant to 100 metres.
The watch features two superimposed dials that together create the illusion of a curved globe. The base dial, made of gold, is finished with a horizontal gradient that shifts from bright sky blue in the centre to dark navy at the edge. On top of this, hand-engraved guilloché lines trace out meridians and parallels, inspired by NASA’s “Black Marble” satellite images of Earth at night.
Above this sits a sapphire crystal dial, on the underside of which lifelike details of the Earth’s continents are painted with Grand Feu enamel. Its upper surface is decorated with hand-painted clouds and layered with Grand Feu enamel. At night, this map lights up like the never-sleeping cities—done without Super-LumiNova, using Breguet’s unique patent-pending phosphorescent enamel technique.
This rich dial is applied with blued-gold Roman numerals and Breguet hands, all coated with light grey Super-LumiNova. On the flange, matching hour markers glow subtly in the dark. Beneath the 12 o’clock sits a date window, while the day/night indicator at 4 o’clock displays a golden Sun with a sunburst finish opposite a hammered half-Moon, both made of Breguet gold.
The Marine Hora Mundi instantly switches from one time zone to another at the press of a button. This is thanks to Breguet’s patented calibre 77F1, which works differently from traditional GMT watches. Instead of an extra hand or sub-dial, the central hands themselves can be used to display both local and reference time. Once the desired city is selected with the crown at 8 o’clock, pressing the integrated pusher makes the hands jump to the chosen time zone. The date and day/night indicators also change forward or backwards in sync. It makes crossing time zones as easy as clicking a button.
Through the sapphire crystal caseback, the movement is seen complete with a gold rotor, Côtes de Genève striping, and perlage finishing. The movement has 384 components, a silicon escapement resistant to corrosion and magnetism, a 4 Hz frequency, and a power reserve of 55 hours.
The Marine Hora Mundi 5555 is paired with a navy blue alligator leather strap secured with a Breguet gold triple-folding clasp, with an additional rubber strap included in a red Moroccan leather presentation case. Only 50 pieces will be made, each individually numbered on the caseback, and the city disc can be customized by the owner. It is priced at CHF 88,000 (approx. INR 98,10,000).
