Watch Spotlight: Patek Philippe Perpetual Calendar Chronograph 5270G (Men’s 18K White Gold)
History at a Glance
The Patek Philippe 5270 continues a distinguished lineage of perpetual calendar chronographs that began in 1941 with the legendary Ref. 1518—the first series-produced perpetual calendar chronograph by Patek Philippe. Over the decades, this lineage evolved through iconic models like Ref. 2499, 3970, and 5970, each a masterpiece in its era.
When introduced in 2011, the 5270 was groundbreaking—it marked the brand’s first perpetual calendar chronograph equipped with a fully in-house, manually wound CH 29‑535 PS Q caliber.
Fun Fact
Upon its debut, the 5270 also became Patek Philippe’s largest perpetual calendar chronograph to date, boasting a 41 mm case—a full millimeter larger than the previous 5970 model.
Technical Highlights at a Glance
-
Movement: In-house, manual-winding CH 29‑535 PS Q calibre featuring chronograph, perpetual calendar (day, date, month, leap-year), day/night, and moon‑phase indications.
-
Case: 41 mm, elegant 18K white gold, completed with a polished concave bezel, angular “horn” lugs, and a sapphire display back that showcases the movement.
-
Dial Layout: Day and month are displayed via twin apertures at 12 o’clock; a combined moon‑phase and date subdial at 6 o’clock; small seconds and 30‑minute chronograph counter; plus leap‑year and day‑night indicators.
-
Case Thickness: Approximately 12.4 mm—a balanced thickness for a watch packed with complications.
Why It Stands Out
Combining a significant history with modern engineering, the 5270G is a horological tour de force: a restored classic dial architecture, full perpetual calendar, chronograph functionality, and Patek Philippe craftsmanship—all encapsulated in a refined white gold frame. Its introduction not only honored tradition but elevated Patek’s technical autonomy with its in-house movement.
