Breguet Marine Big Date 5817BR/Z2/5V8 in 18K Rose Gold

The Breguet Marine Big Date Ref. 5817BR/Z2/5V8 is an exceptional expression of maritime elegance fused with mechanical mastery. Drawing on Breguet’s historic role as official chronometer maker to the French Navy, this contemporary Marine model delivers seafaring utility with aristocratic sophistication.

Crafted in 18K rose gold, the 39mm case commands attention with its polished contours, fluted caseband, and iconic lugs. The deep black dial, highlighted by a radiant guilloché center and luminous Roman numerals, provides a dramatic contrast that accentuates Breguet’s timeless design language. One of the most distinctive features of this model is the oversized date window at 6 o’clock, which offers an elegant solution for everyday legibility.

This timepiece houses an in-house automatic caliber 517GG visible through the sapphire case back, finely decorated with Côtes de Genève stripes and a gold rotor engraved with a wave motif—a nod to its nautical inspiration.
