Breguet Classique Hora Mundi

About this reference

The Breguet Classique Hora Mundi 5717BR/AS/9ZU was introduced in 2011 and remained a staple of the brand’s high-complication catalog for approximately a decade before being succeeded by the 5727 and 5557. This 44mm 18k rose gold reference features the self-winding Calibre 77F0, which utilizes a unique mechanical memory system allowing the wearer to toggle between two pre-selected time zones, including date and day/night synchronization, with a single pusher press. The dial is characterized by a solid gold base with hand-engraved wave motifs and a translucent lacquer finish depicting the Americas. Collectors value this reference for its technical innovation in world-time complications and traditional finishing, such as the fluted caseband and soldered lugs. On the secondary market, this model typically trades between $35,000 and $50,000. While the Americas dial is common, variants featuring the European/African or Asian/Oceanic continents were also produced in limited quantities.
