Breguet Marine Chronograph 5827 5827BA/12/5ZU

Breguet's Marine collection, introduced in 1990, draws on the founder's role as official chronometer maker to the French Navy from 1815. It is the brand's sports-luxury line, with larger cases, crown guards, luminous hands and dials that mix guilloché patterns with nautical motifs such as waves.

The collection was redesigned in 2018 and again in 2023, when titanium became a central material. Key references include the 5517 time-and-date model, the 5527 chronograph and the 5557 Hora Mundi world-time model. Because the generations look similar, confirm the exact reference, case material and dial code against the papers, and check whether the bracelet or the rubber strap is included.
