Patek Philippe Grandmaster Chime 6300/400G-001: The Zenith of Haute Joaillerie

For the elite horological collector, the Patek Philippe Grandmaster Chime 6300/400G-001 stands as the ultimate synthesis of mechanical complexity and extravagant artistry. As a flagship of the Grand Complications collection in 2026, this “Haute Joaillerie” edition elevates the world’s most sophisticated wristwatch into a breathtaking jewelry masterpiece. It is a timepiece that transcends mere utility, serving as a legacy of Patek Philippe’s unrivaled mastery in both engineering and gem-setting.

Radiant Gem-Setting and Invisible Artistry

The defining unique characteristic of the reference 6300/400G-001 is its magnificent exterior. Crafted in a substantial 49.4 mm 18k white gold case, the watch is resplendent with 409 baguette-cut diamonds, totaling an impressive 31.35 carats. The artisans at Patek Philippe have utilized the “invisible setting” technique on the caseband, lugs, and swivel links, creating a seamless, shimmering surface of light where no metal is visible between the stones. This meticulous setting transforms the complex reversible case into a brilliant sculpture of fire and ice.

A Symphony of Twenty Complications

Beneath its diamond-encrusted exterior lies the legendary manually wound Caliber GS AL 36-750 QIS FUS IRM. Comprising 1,366 individual parts, this movement supports a staggering 20 complications, including:

• Five Acoustic Functions: Featuring a Grande and Petite Sonnerie, a Minute Repeater, and two patented world-firsts: an alarm that strikes the programmed time and a date repeater that audibly chimes the date on demand.
• Double-Faced Reversible Case: An ingenious patented rotation mechanism allowing the wearer to alternate between two distinct dials.
• Instantaneous Perpetual Calendar: Displaying the day, month, leap-year cycle, and a four-digit year display in an aperture with perfect precision.
• Ebony Black Opaline Dials: The time side features a hand-guilloched hobnail pattern and white gold applied Breguet numerals, while the calendar side offers a clean, functional layout for the perpetual calendar displays.

Unparalleled Craftsmanship and Exclusivity

Every detail of the 6300/400G-001 is a testament to the “Patek Philippe Seal,” the industry’s most rigorous hallmark of quality. The watch is paired with a hand-stitched, shiny black alligator leather strap featuring a fold-over clasp set with 22 baguette diamonds (1.19 ct), ensuring that the opulence remains consistent from the bezel to the wrist. To complete the ensemble, this exceptional timepiece is often accompanied by matching white gold cufflinks adorned with baguette diamonds, cementing its status as a complete luxury set for the modern connoisseur.
