The Patek Philippe 6300/400G Grandmaster Chime is a pinnacle of horological artistry, combining unparalleled mechanical complexity with dazzling aesthetics. Encased in white gold and adorned with 409 baguette-cut diamonds set in an "invisible setting," this Haute Joaillerie masterpiece showcases opulence. The watch features 20 complications, including five chiming modes, two of which are patented world exclusives: a time-strike alarm and a date repeater that announces the date audibly. The double-faced reversible case, equipped with a patented rotation mechanism, allows wearers to alternate between two distinct dials, offering both functional and aesthetic versatility.

Inside, the manually wound calibre 300 GS AL 36‑750 QIS FUS IRM powers the watch, supporting grande and petite sonnerie, minute repeater, perpetual calendar, second time zone, and multiple power reserve indicators. This exceptional timepiece is accompanied by matching white gold cufflinks adorned with baguette-cut diamonds, emphasizing its status as a complete luxury set.
