Breguet Renews the Marine with the “Quai de l'Horloge” Guilloché on the 5517 and 5527

On September 24, 2026, Breguet unveiled twelve new references for its Marine 5517 and Marine Chronographe 5527, featuring the “Quai de l'Horloge” hand-guilloché pattern and Breguet numerals instead of Roman numerals.

On September 24, 2026, Breguet officially presented new versions of its two benchmark sports models: the Marine 5517, a three-hand watch with date, and the Marine Chronographe 5527, equipped with a flyback chronograph. The announcement covers a total of twelve references, with prices ranging from $26,400 to $93,900 depending on the material and strap option selected.

The most visible update is on the dial. Both models abandon Roman numerals in favor of Breguet numerals, a typography unique to the manufacture and inherited from its historic pocket watches. They also adopt the hand-guilloché pattern named “Quai de l'Horloge”, a decoration introduced during the house's 250th anniversary celebrations in 2025, whose name refers to the Parisian address on the Île de la Cité where Abraham-Louis Breguet kept his workshop. This guilloché is executed by hand on a gold base, then treated and coated with a layer of lacquer to achieve the final shade, giving the dial a characteristic optical depth.

The colors vary according to the case metal. On the Marine 5517, white gold receives an ice blue dial, rose gold a black dial, and titanium a deep blue dial with rose gold hands and hour markers. The 5527, for its part, offers a gradient blue dial in white gold and rose gold, as well as a gradient gray dial for the titanium version. In both cases, the rubber straps feature the texture of the guilloché pattern on their surface, establishing a formal continuity between the most noble part of the watch and its most functional element.

In terms of dial layout, the date has been repositioned to 6 o'clock on both references, whereas it previously occupied a position that disrupted the overall symmetry. On the Marine Chronographe 5527, the hour counter, formerly located at 6 o'clock, has been removed. The chronograph now only retains a minute counter at 3 o'clock and a small seconds subdial at 9 o'clock, freeing up space for the guilloché decoration and simplifying legibility without altering the mechanical nature of the flyback.

The technical specifications remain unchanged. The 5517 is powered by the automatic Caliber 777A, running at 4 Hz with a 55-hour power reserve, housed in a 40 mm case that is 11.5 mm thick and water-resistant to 100 meters. The 5527 relies on the Caliber 582QA, also automatic, composed of 343 parts, with a flyback function, a 48-hour power reserve, and a frequency of 28,800 vibrations per hour. Its case measures 42.3 mm in diameter and 13.9 mm in thickness. On both movements, the balance spring and pallet horn are made of silicon, and the sapphire caseback reveals the gold oscillating weight, whose profile is inspired by a ship's rudder.

Each model is available in titanium, 18-karat white gold, and 18-karat rose gold, with a choice between a three-link metal bracelet and a rubber strap, representing six variations per family and twelve references in total. The Marine 5517 in titanium on a rubber strap is priced at $26,400, while the gold version on a metal bracelet reaches $80,300. The 5527 in titanium on rubber starts at $33,000 and goes up to $93,900 in gold on a bracelet. It is worth noting that this update does not affect the entire Marine collection: the GMT Hora Mundi and the Alarme Musicale remain unchanged.

The symbolic significance of this renewal is part of an asserted continuity. Since Abraham-Louis Breguet was appointed watchmaker to the French Royal Navy by Louis XVIII in 1815, the house has maintained a documented connection with ocean navigation. Its marine chronometers accompanied several expeditions, notably Hyacinthe de Bougainville's circumnavigation of the globe between 1824 and 1826 and Jules Dumont d'Urville's Antarctic mission in 1840. The “Quai de l'Horloge” guilloché pattern and the Breguet numerals applied to these new Marine models constitute, in this respect, a deliberate stylistic anchoring in this heritage. Both models are available now in Breguet boutiques and at authorized retailers.
