First introduced in 2011, the Classique Hora Mundi 5757 replica by Breguet was the first mechanical timepiece with an instant-jump time-zone display system with synchronised date, day/night and city indications.The original date display is based on a dragging disc appearing through a 12 o’clock aperture able to reveal three successive dates at a time.
Breguet is now introducing a new interpretation of this unique timepiece: the Classique Hora Mundi 5727.
In place of a representation of the globe as seen in the first version, the dial of this 2016 edition features a “clou de Paris” hobnailing motif entirely hand-crafted on a silvered gold dial.
The hours and minutes are displayed by means of the famous Breguet open-tipped hands, which sweep around a chapter ring bearing Roman numerals transferred on a circular satin-brushed surface.
The 24-hour indicator located between 3 and 4 o’clock has been adorned with two different types of engine-turning. Its upper part is enhanced with a flame pattern and bears the Breguet inscription, while a cross weave motif graces the lower section stamped with the watch’s serial number.
With its single set of hours and minutes hands and no subdial, the Swiss Replica Breguet Classique Hora Mundi 5757 is unlike other GMT or dual-time watches. This pair of hands is linked to a mechanical memory located beneath the dial and capable of keeping track of the time in two time zones allowing the wearer to adjust the time in two different places in the world, and to display one or the other on demand.
When the Hora Mundi switches from one memorised time to another, the date and the day/night or 24-hour indication, are simultaneously adjusted. All this takes place without disturbing the rate of the watch, whose precision is maintained during time-setting by means of a stop-seconds system.
The legibility of the date is enhanced by a retrograde hand tipped by a protruding circle that frames the current date as soon as it appears in the left-hand part of the aperture and follows it throughout the day until it disappears to the right of the aperture.
At midnight, the hand bearing the circle jumps to return to the left-hand side of the aperture and frame the date of the new day that is beginning.
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 case, available in rose or white gold, has a diameter of 43 mm and it is 12.6 mm thick – almost 1 mm slimmer than the 2011 version of the Classique Hora Mundi. The caseband with fluted sides and welded strap lugs are typical details of Breguet timepieces.
