This year, Breguet launched a new watch – Hora Mundi 5727, a successor to 2011’s award-winning Breguet Hora Mundi which was the first mechanical timepiece with an instant-jump time-zone display system with synchronised date, day/night and city indications. A new interpretation of this unique timepiece – the Hora Mundi 5727 features a case in 18-carat white gold with a delicately fluted caseband and sapphire-crystal caseback. The dial of 43mm case is in silvered 18-carat gold.
The hours and minutes are displayed by means of the famous Breguet open-tipped hands in blued steel, which sweep around a chapter ring bearing Roman numerals transferred on a circular satin-brushed surface. 24-hour indicator is located between 3 and 4 o’clock, city indication at 6 o’clock and date aperture is at 12 o’clock. Instant time-zone jump with synchronised date, 24-hour and city indications.
Covered by four patents, the self-winding Calibre 77F0 is composed of the base Calibre 777 with an additional module. Beating at 28,800 vibrations per hour and offering a power reserve of 55 hours, it features an inverted in-line Swiss lever escapement with silicon pallets and silicon balance-spring. The watch is water resistant to 3 bar (30m). Hora Mundi 5727 is available in either white or rose gold.
