Breguet Reine de Naples White Gold — Jour/Nuit Diamond Silver Dial | Ref. 8998BB/11/974/D00D

The Reine de Naples 8998 Jour/Nuit stands apart from every other reference in the collection by virtue of its central complication: a day/night indicator that distinguishes the hours of sunlight from those of darkness — an indication of particular practical and poetic significance on a watch designed for a woman's wrist. On the 8998BB/11/974/D00D, this complication is expressed through calibre 78CS, a self-winding movement developed specifically for this purpose, providing approximately 57 hours of power reserve — the most generous in the Reine de Naples collection.

The 32 mm white gold case, 10.6 mm deep and set with a diamond-encrusted bezel, frames a silver dial of refined simplicity. The Jour/Nuit display integrates harmoniously with the dial's architecture, its indicator marking the passage from day to night with quiet mechanical certainty. The sapphire exhibition caseback offers a privileged view of calibre 78CS's construction — its movement bridges lavishly finished, the rotor signed and engraved in the manner that has distinguished Breguet's work since the eighteenth century.

Presented on a black leather strap that emphasises the white gold case's cool luminosity, the 8998BB/11/974/D00D is, at $104,880, the most significant investment in this selection — and it justifies that position through the rarity of its complication, the quality of its construction, and the completeness of its conception. Few watches in any collection combine a ladies' format with genuine horological ambition as successfully as this Reine de Naples Jour/Nuit.
