Breguet invites you to escape with a new interpretation of its Hora Mundi model within the Marine collection, a timepiece combining technical and aesthetic feats. Travel at a click. The Hora Mundi became an instant hit at the time of its launch. This mechanical watch, which had taken three years to develop and been awarded four patents, featured a critical asset in the shape of an instant-change dual-time display with a memory function.

This technical feat is accomplished via the pusher and crown. Having selected the first city’s time and date, the watch owner need only set the second city. The watch mechanism then calculates the time and date using a clever system of cams, hammers and an integrated differential.

At that point, simply pressing the pusher is enough to travel from one end of the planet to the other, all without disturbing the accurate running of the watch.

The dial offers a fascinating interpretation of the world on the wrist by playing on materials and superimposed plates. On the first gold base, the hand-guilloché waves lap gently against the shores of the continents. The sunburst dial base attired in abyssal blue creates the impression of a permanent waltz of the wave motifs.

This effect may also be due to how the continents are depicted: an additional plate made of sapphire is composed of the metallised meridians, and the continents are treated to horizontal satin brushing, while their coastlines are subtly outlined with a metallic turquoise border.

Finally, an outer flange serves as a support for the various elements present on the dial. The result features brilliantly crafted dimensions and surfaces thanks to various treatments requiring several weeks of work. The importance of details makes the dial legible while endowing each indication with a special aesthetic.

The Sun and Moon positioned at 4 o’clock are hand-hammered to create a strongly realistic result. While the sun is a luminous rose gold, the moon is rhodium-plated and exudes a mysterious grey appearance. Displayed through a 12 o’clock aperture, the date features an additional retrograde hand ingeniously placed beneath the aperture dial and featuring a delicately rounded “U-shaped” tip serving to encircle the date of each passing day.

The subtle finish referred to as brouillage is an ancient watchmaking decoration that has been updated and creates a matt yet shiny effect. It also facilitates reading while remaining discreet. The cities corresponding to the different time zones are indicated at 6 o’clock. A metallised anchor appearing above the window serves to determine the place whose current time you wish to consult.

A unique movement The 43.9 mm-diameter case, available in a choice of white or rose gold, houses Calibre 77F1 whose balance oscillates at a frequency of 4 Hz. This mechanical self-winding movement is fitted with an escapement made of silicon, a material with multiple properties that is resistant to both corrosion and wear. It is also insensitive to the effects of magnetic fields.

Part of this exceptional mechanism with its 55-hour power reserve can be admired through the sapphire caseback, elegantly adorned with Côtes de Genève, guilloché and snailed finishing. Ready to travel the world, the new Marine Hora Mundi is available with either a leather strap, a rubber strap or a gold bracelet.
