Breguet 5717BR Classique Hora Mundi 18K Rose Gold Silver Dial

The Breguet Classique Hora Mundi reference 5717BR/US/9ZU is one of the more technically original travel watches of the modern era, introduced in 2011 as part of the Classique collection. Cased in 18K rose gold, this America version pairs Breguet's traditional fluted caseband and welded lugs with a silver-toned guilloche gold dial centered on a hand-engraved map of the Western Hemisphere beneath translucent lacquer. What sets the watch apart is its patented instant-jump dual time system with memory, allowing the wearer to store two cities and switch between them at the push of a button while the time, date, day and night indication all synchronize at once. That functionality is driven by the self-winding Breguet caliber 77F0, a sophisticated movement based on the maison's caliber 777 and developed to deliver one of the most intuitive mechanical world-travel complications on the market. Collectors value the 5717 because it does not simply display a second time zone; it fundamentally rethinks how a traveler interacts with a mechanical watch. The dial execution is equally important, combining engine-turned engraving, applied cartography, Roman numerals, and blued Breguet hands in a way that feels unmistakably rooted in the brand's classical vocabulary. Unlike a generic GMT, the Hora Mundi carries genuine horological significance as one of the first mechanical watches to unite an instant time-zone jump with synchronized indications and memory. The US-suffix reference is not a boutique edition, but it is a region-specific execution distinguished by its Americas map and city program, which gives it a more specialized collecting profile than standard global-travel pieces. For buyers who appreciate traditional case architecture but want a movement with real conceptual depth, the 5717BR/US/9ZU remains one of Breguet's most compelling contemporary complications.
