Patek Philippe Grand Complications White Gold — Black Dial | Ref. 6300/400G-001

There are watches, and then there is the Grandmaster Chime Haute Joaillerie 6300/400G-001 — a 49 mm white gold monument to everything Patek Philippe has learned across 187 years of uninterrupted watchmaking. Introduced as the centrepiece of Patek's 175th anniversary celebrations, the Grandmaster Chime houses twenty complications, including five chiming functions: a grande sonnerie that strikes the hours and quarter-hours automatically, a petite sonnerie, a minute repeater, an alarm with strike confirmation, and a striking mechanism that announces the time at the touch of a pusher. The manually wound movement is a complete manufacture achievement — no other living watchmaker makes anything like it.

The 6300/400G-001 adds the Haute Joaillerie dimension: the bezel is set with diamonds, transforming an already extraordinary technical object into a piece of wearable art that blurs the boundaries between watchmaking, jewellery, and sculpture. The black dial carries Arabic numerals that provide human scale against the watch's monumental 49 mm case, while the transparent case back reveals an architecture of breathtaking density. Each side of the reversible case presents a different dial face — a practical innovation as remarkable as any of the movement's complications. The screw-down crown, fold-over clasp, and alligator leather strap ensure that wearing this titan of horology is as secure as it is extraordinary.

Priced at nearly $4.5 million and produced between 2017 and 2022 with box and papers, the 6300/400G-001 exists at the absolute summit of what a private individual can acquire in new or near-new watchmaking. It is not offered to those who merely wish to own an exceptional watch. It is offered to the rare collector for whom watchmaking is a lifelong passion — and for whom the next generation deserves nothing less.
