Patek Philippe 6159G-001 Perpetual Calendar Silver Dial White Gold Watch

Patek Philippe Retrograde Perpetual Calendar – Ref. 6159G-001

The Patek Philippe 6159G-001 is a contemporary reinterpretation of one of the brand’s most iconic complications. This model blends classic perpetual-calendar architecture with a modern aesthetic, offering a bold new expression within Patek Philippe’s Grand Complications collection.

The watch is housed in a 39.5 mm 18k white-gold case, designed with refined proportions and an elegant profile. A defining feature is the Clous de Paris hobnail-decorated bezel and caseback, adding texture and traditional craftsmanship to the exterior. Despite its intricate mechanics, the watch maintains a slim silhouette at approximately 11.5 mm, making it suitable for both formal and sophisticated everyday wear.

The dial is one of the most distinctive elements of the 6159G-001. Crafted from smoked sapphire crystal with grey metallization, it achieves a subtle transparency that reveals glimpses of the movement beneath while remaining perfectly legible. The dial transitions from light to dark, creating visual depth along the edges. Polished white-gold baton hour markers and dauphine-style hands, both with luminescent accents, provide clarity against the modern, semi-transparent surface.

The perpetual calendar layout is executed with remarkable symmetry. A retrograde date display arcs gracefully across the center of the dial, with a hand that sweeps back to the starting position at the end of each month. The day, month, and leap-year indicators are arranged in crisp apertures for intuitive reading. A beautifully rendered moon-phase indicator completes the design, adding a touch of classical charm to the contemporary dial layout.

Powering the 6159G-001 is the Caliber 26-330 S QR, a self-winding movement engineered for precision and long-term reliability. Operating at 28,800 vibrations per hour, it provides a power reserve of 35 to 45 hours. The caliber automatically accounts for varying month lengths and leap years, requiring no adjustment until the year 2100. Through the sapphire caseback, the movement’s refined finishing—gold rotor, Geneva stripes, chamfered edges—can be fully appreciated.

The watch is fitted with a black composite strap that carries a fabric-like texture, giving the piece a subtle sport-elegant character and enhancing its modern identity. A white-gold folding clasp secures the strap while maintaining the cohesive luxury of the design. Water resistance is rated at 30 meters, consistent with its status as a complication-focused dress watch.
