Breguet has spent 2026 quietly re-arguing the case for the Marine, and this week the argument reached its two flagships. The Marine 5517 and Marine Chronograph 5527 return with dials engraved with a new guilloché motif named for the Quai de l’Horloge — the Île de la Cité address where Abraham-Louis Breguet set up shop in 1775 — its rippling pattern sealed under semi-transparent coloured lacquer that shifts with the light like harbour water at dusk.

The wave motif of the outgoing models is gone, and so are the Roman numerals: in their place, applied Breguet numerals in 18k gold, with the date resettled at six o’clock for symmetry. Each reference comes in three metals. In titanium, the 5517 wears a smoked deep blue and the 5527 a grey-to-black gradient; white gold brings glacial ice-blue tones; rose gold pairs with black and navy. Cases are unchanged in their essentials — 40mm for the three-hander, 42.3mm for the chronograph, both good for 100 metres with screw-down crowns.

Inside, the in-house calibre 777A drives the 5517 with a 55-hour reserve, while the 5527 keeps its 582QA flyback chronograph. Prices run from CHF 20,000 for the titanium 5517 on rubber to CHF 71,100 for the gold chronograph on bracelet — and these are permanent-collection pieces, available now.

It amounts to a subtle but decisive shift: less sport, more couture. The Marine has always been the Breguet you could wear to sea; engraved with the address where it all began, it is now equally a Breguet that carries its history on its face.
