Housed in an 18-carat white gold case measuring 39.5mm in diameter and 9.8mm thick, the Millenary reference 77247BC.ZZ.1272BC.01 is framed by a diamond-set bezel and lugs set with 116 brilliant-cut diamonds totalling approximately 0.60 carats. Glareproofed sapphire crystal protects both the front and caseback, while the crown is finished with a pink sapphire cabochon. Water resistance extends to 20 metres.
The dial presents a white mother-of-pearl off-centred disc accompanied by a small seconds counter, anthracite Roman numeral transfers, and pink gold hands — an arrangement that reflects the Millenary's signature asymmetric layout. The hand-wound movement is visible through the sapphire caseback.
Completing the watch is an 18-carat white gold bracelet secured by a folding clasp, carrying through the case's precious metal throughout the entire piece.
