Breguet Marine Hora Mundi Offers A Fresh New Perspective

Breguet Marine Hora Mundi Offers A Fresh New Perspective

Breguet’s 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.

Manufacture Breguet offers a new interpretation of its Hora Mundi model within the Marine collection, a timepiece combining technical and aesthetic feats. This technical feat is accomplished via the pusher and crown. Having selected the first cities time and date, the owner of the watch need only set the second city. The watch mechanism then calculates the time and date by means of 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 a play on materials and superimposed plates. On the first gold base, the hand-guillochéwaves 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 the way in which 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 new Breguet Marine Hora Mundi is available with either a leather strap, a rubber strap or a gold bracelet.
