Replica Breguet unveiled the Breguet Hora Mundi 5717 in 2011 with its hand-engraved map of America, Europe, Africa or Asia and Oceania on the dial. The brand has released a more classical but equally stunning version of the model for 2016. It’s called Classique Hora Mundi 5727 and features the signature instant time zone system with memory.

Breguet Mens Replica is now introducing a new interpretation of this major timepiece: the Classique Hora Mundi 5727 replica watch. In place of a depiction of the globe, the dial of this 2016 edition features a “clou de Paris” hobnailing motif entirely hand-crafted on a silvered gold dial.
