Breguet introduced new versions of the Reine de Naples. Here are the photos along with the descriptions from the press releases. I did not take photos from all new variations, hence I included some press photos, which are easily recognizable.

BREGUET RÊVE DE PLUME HAUTE JOAILLERIE


I get in general not too excited about high jewellery watches, but look at the beautiful execution of the case – outstanding indeed.

BREGUET RÊVE DE PLUME HAUTE JOAILLERIE
The Plumes collection draws its inspiration from the story of Queen Marie-Antoinette of France, wife of Louis XVI and the Breguet company's effective ambassador for ladies' jewellery watches. This guardian of time never stopped writing to her husband the king as well as to her family in Austria. Marie-Antoinette used her pen to express the desire for freedom that pervades her correspondence. This universe led to the creation of very poetic timepieces developed on such ancient decorative methods as engraving or uncommon gemsetting techniques that recall the featherweight delicacy of a quill pen.
This year, the Plumes collection is enriched by a new watch called Rêve de Plume. This timepiece in rose or white gold features the sculpture of a feather that starts at the spherical gem-set attachment at 6 o'clock and goes on to follow the left side of the bezel. Breguet's craftsmen and women resorted to diamonds of different sizes to represent every part of the feather. Thus the central 'shaft' part of the feather is set with baguette diamonds that taper as they approach the end. Similarly, the elements evoking the 'weblike' part of the feather are set with brilliant-cut diamonds of varying sizes, like drops of water sliding along a plumage. Despite the complex setting of diamonds, the piece as a whole gives an impression of lightness and effortlessness. The dial in white mother-of-pearl features a new engine-turned pattern, which again conjures up the delicate vanes of the feather, spreading out from 6 o'clock on the dial. Using engine-turning techniques to add another dimension is a delicate operation because mother-of-pearl is extremely brittle. Indicating the hours and minutes with open-tipped hands in blued steel, this watch is also set with diamonds on the bezel and the flange while the crown is surmounted by a briolette-cut diamond. This outstanding piece once again demonstrates the attention to detail that characterises all of Breguet's creations. The sides of this jewellery watch are finely engraved with feathers, rather like the delicately fluted casebands that are one of the identifying features of a Breguet watch.

BREGUET REINE DE NAPLES HAUTE JOAILLERIE 8909

At the heart of the Reine de Naples collection, the reference 8909 made its appearance to much comment in the press. Indeed, this timepiece in such an iconic shape wore an exquisite bracelet set with diamonds and sapphires. Furthermore the dial displayed a studied mix of bluish natural mother-of-pearl, white gold and diamonds. The combination was highlighted by baguette diamonds set into the bezel and caseband. This year, the Breguet company's artisans decided to create a version of this outstanding piece in rose gold. While the first model evoked the immaculate snows of the North, this version calls to mind the warm tones of the East. The clarity of the diamonds on the bezel and caseband are as stunning as ever, while the sapphires on the bracelet have given way to flaming red rubies. In this watch, the dial is more contrasted, with the crimson glow of the rubies standing out against Tahitian mother-of-pearl. Fitted with a self-winding movement, this timepiece shows the hours and minutes on a subdial in silvered gold set with diamonds. The aperture for the moon can be seen at 12 o'clock with the power-reserve indicator.
The diamonds in this jewellery watch total around 16 cts.

BREGUET REINE DE NAPLES PRINCESSE MINI 9807
Besides these high jewelry pieces, Breguet showed two versions with mother of pearl dials. Re. 9807 is the steel version and Ref 9808 is the red gold version. I did not take pictures of them and therefore include the photos from the press release:

BREGUET REINE DE NAPLES PRINCESSE MINI 9807 & 9808
In 1810, Abraham-Louis Breguet produced the first wristwatch for Caroline Murat, queen of Naples. This timepiece is noted for the delicate shape of its case with its elegant curves that, apart from being an ode to femininity, cannot but evoke the origins of all life. The watch is not only distinguished by its emblematic shape, but also by its movement. While many watchmakers produce mechanical movements for men only, Breguet has since its beginnings designed mechanical timepieces for women. This year, the Reine de Naples collection welcomes two new versions to the expected delight of those with slender wrists. The seductive power of the collection is concentrated in these Reine de Naples Princesse Mini models, measuring 32.7 x 27.3mm. The first version comes in a steel case with a self-winding movement. Its domed dial is in
shimmering white natural mother-of-pearl, while the hour markers are in a marquetry of natural white mother-of-pearl. This is a real achievement because mother-of-pearl is naturally brittle, making its use in marquetry particularly tricky. Another version has also been made, this time in a rose gold case. It has the same movement as the steel watch, but the domed dial is slightly different, being made of mother-of-pearl from Tahiti. Another feature exclusive to the rose gold model is that the spherical attachment of the strap is set with diamonds while the crown wears a briolette diamond.
