Patek Philippe Grand Complications Ref. 5308G-001 White Gold

The Pinnacle of Fine Watchmaking

The Grand Complications Ref. 5308G-001 stands as one of Patek Philippe’s most extraordinary achievements—a timepiece that unites multiple hallmarks of haute horology into a single, breathtaking creation. Presented in 18K white gold and measuring a commanding yet elegant 42 mm in diameter, this masterpiece demonstrates the perfect balance between technical innovation and aesthetic refinement.

A Quadruple Complication of Rare Prestige

The Ref. 5308G-001 is not merely a watch; it is a quadruple complication that brings together four of the most celebrated functions in watchmaking:

• Minute Repeater – A chiming mechanism of sublime acoustic clarity, handcrafted to Patek Philippe’s exacting standards. Each note resonates with warmth and precision, making every chime a miniature concert on the wrist.

• Split-Seconds Chronograph – A highly sophisticated mechanism that allows measurement of intermediate times, equipped with two patented innovations: a backlash-free chronograph clutch ensuring flawless hand movement, and an isolator system that reduces energy loss when the split-seconds hand is stopped.

• Instantaneous Perpetual Calendar – An exceptional technical feat that allows the day, date, and month to advance simultaneously within 30 milliseconds, ensuring perfect legibility and effortless transitions at midnight.

• Moon-Phase and Additional Indications – A poetic display of lunar cycles at 6 o’clock, paired with leap-year indication and day/night display, reinforcing both functionality and visual harmony.

Together, these four complications create an instrument of unmatched horological complexity—yet designed to be read at a glance and worn with comfort.

The Dial: An Ice-Blue Masterpiece

The face of the watch is as captivating as its mechanics. A luminous ice-blue sunburst dial radiates elegance, subtly shifting tones under varying light. The dial is adorned with white-gold baton indexes and faceted dauphine hands, each meticulously polished to capture the play of light. Three calendar apertures stretch gracefully across the upper arc of the dial, while the moon-phase and small-seconds counter anchor the composition at 6 o’clock.

The aesthetic is one of balance, clarity, and sophistication—a design language that speaks directly to collectors who value both technical mastery and visual poetry.

The Case: Strength in White Gold

Crafted from 18K white gold, the case measures 42 mm across and 17.71 mm in height. Its most distinctive feature is the set of open-worked lugs, a sculptural element that lightens the profile while enhancing the watch’s noble presence. The case is offered with a solid white-gold back for discretion, or a sapphire-crystal exhibition back to admire the intricate Caliber within. Every angle is polished by hand, affirming Patek Philippe’s reputation for uncompromising craftsmanship.

The Movement: Caliber R CHR 27 PS QI

Beating at the heart of the Ref. 5308G-001 is the self-winding Caliber R CHR 27 PS QI. This movement is a marvel in itself, comprising 799 individual components and 67 jewels—each painstakingly finished by hand according to the standards of the Patek Philippe Seal.

A platinum micro-rotor ensures efficient winding while preserving the slim profile of the caliber. Operating at a frequency of 21,600 vibrations per hour (3 Hz), the movement delivers a power reserve of 38 to 48 hours depending on chronograph usage. The architecture of the movement is as much art as science, featuring traditional Geneva stripes, chamfered edges, and meticulous hand-finishing visible through the exhibition back.

The Strap: Elegance Secured

The watch is paired with a hand-stitched navy blue alligator leather strap, chosen to harmonize with the ice-blue dial. Its glossy finish adds refinement, while a patented fold-over clasp in 18K white gold secures the timepiece with comfort and confidence.

A Statement of Legacy

The Patek Philippe Grand Complications Ref. 5308G-001 is not a watch for everyday life—it is a horological sculpture, designed for connoisseurs who understand and appreciate the highest expressions of watchmaking art. With its quartet of rare complications, its innovative engineering, and its timeless aesthetics, it occupies a place among the most prestigious creations ever crafted by Patek Philippe.

In the world of fine watchmaking, where innovation must harmonize with tradition, this watch represents nothing less than the pinnacle of the Grand Complications collection. It is both a celebration of heritage and a testament to what is still possible when the limits of mechanical ingenuity are pushed to new heights.
