Breguet Unveils Marine Haute Joaillerie 9509 Poseidonia

by Hours and Minutes Australia

Inspired by the beauty of the seas, to be more specific, a seagrass species that is endemic to the Mediterranean Sea called Poseidonia Oceanica, Breguet presents the new Marine Haute Joaillerie 9509 Poseidonia.

Sitting snugly on any woman’s wrist, at 35.80mm, this petite beauty is encased in an 18-karat white gold round case. The bezel despite being set with the purest baguette-cut diamonds, beautifully facilitates reading. The sides of the white-gold case and the crown are delicately fluted, alternating between polished white gold and baguette-cut diamonds. A briolette-cut diamond tops the crown, claw set with six baguette-cut diamonds. The crown protection is set entirely invisibly with 14 baguette-cut diamonds. The setting continues to the clasp of the strap buckle, echoing the inset bezel and the shape of the open-tipped Breguet hands. The B for Breguet stands out against the slightly colored metallic finish in the center of the buckle. All these varying elements come together in a manner that radiates effortless charm and an essence of pure femininity—something only the master jewellers at Breguet could achieve.

The dial showcases arabesques of the Poseidonia Oceanica plant using invisible-set gemstones. The radiance of 85 baguette-cut diamonds, totalling approx. 2.56 carats interplays wonderfully with the Tahitian mother-of-pearl dial. Breguet’s artisans select each mother-of-pearl attentively to harmonize its iridescent pattern, unique to each gem, with the inset curves of the Poseidonia. Together, their radiance evokes rays of sunshine playing on the sea’s surface. The lines of the pattern unfurl, with diamonds extending out to the lugs of the strap. You’d think that so many diamonds would look too ostentatious, but the Marine Haute Joaillerie 9509 Poseidonia, still manages to look dainty and pretty.

Creating a stunning contrast are the gold Breguet hours and minutes hands. The tip of the second hand reveals the letter B of the maritime code of signals – a distinctive feature of the Marine collection.

In addition to the diamond and Tahitian mother-of-pearl Marine Haute Joaillerie timepiece, Breguet is introducing three other versions available with white mother-of-pearl marquetry: sapphire-set blue (Featuring a combination of blue sapphires, amethysts, colored sapphires, tsavorites, and diamonds), ruby-set red (Featuring a combination of rubies, colored sapphires, and diamonds) and emerald-set green (Featuring a composition of emeralds, tsavorites, colored sapphires, and diamonds). In each version, the curves of the Poseidonia are set in different colors. Each of the 85 gems composing the pattern is selected for its hue, is then cut and set invisibly.


Under the white gold case beats an extra-thin, self-winding 591C caliber, whose bridges are engine-turned by hand with the Marine motif – inspired by the deck of a ship. On the bevel of the white-gold rotor, the sparkling diamond border contrasts with the intensity of the Tahitian mother-of-pearl. The words Horloger de la Marine (Watchmaker to the Navy) are engraved on the rim of the caseback in white gold. This refers to the title of Chronometer-maker to the French Royal Navy bestowed upon Abraham-Louis Breguet in1815.
