Review: Breguet Hora Mundi Watch

Breguet’s signature worldtimer, the Hora Mundi, is reintroduced with a less ornate look

Jul 19, 2016 | By Ruckdee Chotjinda

When the Classique Hora Mundi 5717 watch was launched, it stood out with its depiction of the world’s continents on a silvered gold dial. This year, the Breguet Classique Hora Mundi 5727 is introduced with the same complication, but without its predecessor’s visual representation of the continents – the dial bears clou de Paris guilloché instead. More engine-turning work is found on the 24-hour sub-dial, whose upper and lower halves, which correspond to the day and night, show the flame and cross weave motifs respectively.

The new iteration may be powered by the same engine underneath the dial, but it looks completely different, and arguably more wearable in everyday settings.

Breguet holds four patents associated with the Hora Mundi thanks to its unique complication, which is programmed to track and display the time in two cities on demand. When the crown at eight o’clock is pushed, the watch’s hour hand, 24-hour indicator, and date display at 12 o’clock simultaneously change from one preselected time zone to the other. Setting these two desired time zones is easily done by pulling the same crown out and turning it forwards or backwards until the desired city appears in the window at six o’clock.

The previous Hora Mundi, 5717, measures 43mm wide and 13.55mm thick. The new version, 5727, has the same diameter but clocks in at a slightly thinner 12.6mm. It is available in either white or rose gold.
