Breguet Marine Dame White Gold — Marea Motif Mother-of-Pearl Dial | Ref. 9518BB/V2/984/D000

The Marine Dame 9518 in 18-carat white gold exemplifies Breguet's conviction that a watch for women need not sacrifice an ounce of mechanical credibility to achieve its decorative ambitions. At 33.80 mm across and a remarkably slender 9.89 mm in depth, the white-gold case wears with the lightness of a fine jewel while housing a fully developed self-winding movement and an exhibition sapphire caseback that displays calibre 591A in its entirety. The diamond-set bezel — each stone carefully matched for colour, clarity, and cut — encircles the dial with a brilliance that transforms the watch into an object of gemological as well as horological distinction.

The marea motif on the mother-of-pearl dial is the piece's defining signature: a pattern that evokes the play of tidal currents across shallow coastal water, engine-turned or printed with exceptional precision to create depth and movement in a material already celebrated for its iridescent beauty. Applied Breguet numerals in white gold mark the chapter ring, their delicate open-tipped serifs lending a historic gravity to the composition, while slim blued steel hands complete the ensemble with the understated elegance Breguet has refined over two and a half centuries.

Calibre 591A provides approximately 38 hours of power reserve from its self-winding rotor, sufficient for continuous weekend wear, and the case is rated water-resistant to 50 metres. Presented on a blue leather strap that coordinates with the dial's oceanic theme, the 9518BB/V2/984/D000 at £29,360 is a distinguished proposition for the collector who values the complete Breguet experience in a feminine format of genuine horological substance.
