Breguet's new Hora Mundi is in six different iterations

Launched more than a decade ago, the Hora Mundi by Breguet is best known for its distinctive instant time zone jumping mechanism. This year, the watchmaker has introduced a new version of the watch, the 5557-Marine Hora Mundi, with a significantly updated display.

In 2011, when Breguet first unveiled their Hora Mundi timepiece as part of the Classique collection, the horological world took immediate notice. Unlike any other GMT model, it featured an ingenious instant time zone jumping mechanism, which displayed either time of the city one is travelling to or home time ‘on-demand’, along with the synchronised date and day/night indications. Needless to say, the Breguet Hora Mundi became an instant hit and was awarded four patents. Now, building on the rich legacy of the watch, Breguet has released its brand new version, the 5557-Marine Hora Mundi, which is available in 18K white or rose gold. 

Although the latest 43.9mm 5557-Marine Hora Mundi model, now offered within the Marine collection instead of the Classique range, is functionally and technically more or less similar to its predecessors, in terms of the looks, it has a lot more to offer. The dial comes with a gold base that features a blue backdrop of hand-guilloché waves that lap against the shores of the continents with their coastlines outlined with a metallic turquoise border. The continents are depicted with the help of an additional sapphire plate, which is composed of metallised meridians. To make sure that the watch offers optimal readability even in low light conditions, Breguet has coated the Roman numerals, timekeeping hands, and the nautical pennants and dots on the blue chapter ring with an ample amount of luminous material. What’s more, the display of 5557-Marine Hora Mundi also features a day/night indicator with hand-hammered sun and moon at 4 o’clock, an aperture at 6 o’clock that shows the city for which the hands show the time and a date display in a window at 12 o’clock.

In order to set the time, the wearer has to first select the home time or first city’s time by using the crown at 8 o’clock and the pusher at 4 o’clock. Next, to set the second city’s time they need to just choose the name of the second city by using the crown and the watch will automatically set the time date, and day/night display by means of a system of cams, hammers, and an integrated differential. 

Under the hood, the new Breguet Hora Mundi comes with Calibre 77F1, which beats at a frequency of 4Hz and is capable of storing a minimum power reserve of at least 55 hours. The movement features an escapement constructed from silicon to protect it from corrosion and magnetic fields. Visible through an exihibition caseback, the calibre 77F1 is decorated with Côtes de Genève, guilloché, and saniled finishing. The 5557-Marine Hora Mundi is available in six different iterations, including the option of gold bracelets, and leather and rubber straps, with a triple-blade folding clasp.
