Pre-Owned Breguet Marine Royale Alarm 45mm 18K White Gold — Black Rhodium Dial, Full Set Dated 2011 (Ref. 5847BB/92/5ZV)
On the 27th of October 1815, King Louis XVIII appointed Abraham-Louis Breguet Chronometer-Maker to the French Royal Navy. The modern Marine Royale Alarm is the maison’s deliberate citation of that appointment — an alarm wristwatch that functions underwater, two hundred years after the first Breguet marine chronometers were set into the holds of French naval ships.
Available now at Black Tag Watches (Aventura, Florida), this 2011 example — reference 5847BB/92/5ZV — is cased in 18K white gold with a black rhodium dial, powered by the in-house calibre 519R mechanical alarm, water-resistant to 300 metres, and offered complete with its original Breguet box, warranty certificate dated 2011, and an additional alligator strap.
What Is the Breguet Marine Royale Alarm?
A Collection Descended from an 1815 Royal Appointment
Breguet’s Marine collection is not a thematic sport line in the contemporary sense. It is the direct lineal descendant of the specific commission Abraham-Louis Breguet received on the 27th of October 1815, when King Louis XVIII appointed him Chronometer-Maker to the French Royal Navy. From that date forward, Breguet produced a series of one-day, two-day, and eight-day marine chronometers for naval service, signed “Breguet et Fils, Horlogers de la Marine Royale,” and installed in the captain’s quarters of French naval vessels to determine longitude at sea. For collectors of pre-owned Breguet, the Marine line carries a provenance that most modern sport collections cannot claim — it is a direct citation of a two-century-old naval appointment rather than a marketing theme.
From Historical Chronometer to Modern Alarm Wristwatch
Three surviving historical chronometers specifically — including a two-day marine chronometer sold by the maison in 1822 — are cited by Breguet as the direct inspiration for the modern Marine Royale Alarm wristwatch, reference 5847, launched in 2010. The reference is a 300-metre dive watch with a mechanical alarm complication: a working instrument that extends the Marine line’s naval heritage into a genuinely functional modern tool watch. This example is offered in white gold — the materially rarer configuration relative to the rose-gold variant — with a complete original delivery dated 2011.
Dial & Case Design: Fluted White Gold, Wave-Crest Guilloché
Case Construction and the Marine Signature
The 45mm case is rendered in 18K white gold and stands 17.5mm thick — proportions shaped by the dual-barrel architecture required to drive both the time movement and the independent alarm mechanism — with the Marine collection’s signature fluted case flanks, a stylistic motif Breguet carries across the line as a citation of its own early-nineteenth-century vocabulary. A unidirectional rotating bezel surrounds the dial for dive-time tracking. The case is substantial by necessity: the alarm complication requires the space, and the 300-metre water resistance requires the construction.
The Black Rhodium Dial and Alarm Indicators
The black rhodium dial carries the maison’s hand-engraved guilloché — a wave-crest pattern specific to the Marine collection — with applied Roman numeral hour markers and the signature Breguet “pomme” moon-tipped hands in gold. The alarm functions are integrated into the dial without crowding it: a small aperture at 12 o’clock displays a note symbol when the alarm is activated, a power reserve indicator at 10 o’clock monitors the alarm’s independent mainspring, and a date aperture sits at 6. The alarm time itself is indicated by a short arrow-head hand with blue luminescent material, set with a rubber-sheathed secondary crown; a dedicated gold push-piece at 8 o’clock toggles the alarm on and off. The dial reads as working instrument rather than decoration — every function occupies its own geometry.
Movement: Manufacture Breguet Calibre 519R — Mechanical Alarm
The Independent Alarm Barrel
Inside the Marine Royale Alarm is the manufacture Breguet calibre 519R — an in-house automatic movement of 36 jewels running at 28,800 vph (4 Hz) with a 45-hour power reserve, developed and produced entirely by Breguet at the maison’s Vallée de Joux facility. The 519R is one of the more specifically-engineered calibres in the modern Breguet catalogue: it carries a dedicated independent alarm barrel with its own mainspring and striking-hammer configuration, meaning the alarm is powered separately from the going train and does not deplete the watch’s running power reserve when activated. The separate power reserve indicator at 10 o’clock monitors that alarm barrel independently.
An Alarm That Works Underwater
The alarm hammer strikes a gong configured specifically to remain audible both in air and — unusually among mechanical alarm wristwatches — underwater, where the lower ambient noise of the aquatic environment actually clarifies the alarm’s sound relative to above-surface conditions. The movement is signed, numbered, and visible through the sapphire display caseback; the engine-turned 18K gold oscillating weight is hand-finished and individually numbered. The alarm complication is one of the least-produced classes in modern haute horlogerie — Breguet and Jaeger-LeCoultre’s Memovox are the primary serious contemporary manufacture examples — and the 519R is Breguet’s own in-house execution of it.

Why Buy a Pre-Owned Breguet Marine Royale Alarm?
One of the Rarest Modern Complications
The Marine Royale Alarm 5847 occupies a specific corner of the modern Breguet secondary market — recognised by collectors who read a mechanical alarm complication as a substantive horological argument rather than a tool-watch curiosity, and largely bypassed by buyers whose Breguet familiarity stops at the Classique and Tradition dress lines. The mechanical alarm wristwatch is one of the rarer modern complications in serious manufacture production: outside of Jaeger-LeCoultre’s Memovox lineage and this Breguet calibre 519R family, the alarm complication is almost entirely absent from the contemporary high-horology catalogue. That scarcity of the complication itself — not just the reference — is the collector’s argument.
A Discontinued White-Gold Reference, Fully Documented
Combined with the Marine-line heritage anchored on an 1815 royal appointment, the dive-functional 300-metre specification, and the materially rarer white-gold case configuration, the 5847BB occupies a position in the market that its production numbers reflect: full-set white-gold examples from within the production window are increasingly difficult to source, and original retail approached $45,000 to $50,000 at delivery. Against contemporary white-gold complication retail — and against the current Breguet catalogue, which no longer offers the Marine Royale Alarm as an active reference — this 2011 example offers direct entry into one of the maison’s more historically-cited modern complications at a level that rewards horological literacy over badge recognition, with a complete original delivery, the additional alligator strap, and the signed white-gold buckle intact.
