What makes the reference 5327 especially different is the larger case. Patek Philippe increased the diameter of the watch to 39mm, against 37.2mm for the reference 5140. This doesn’t seem like a big deal yet it is. This small increase in size has a big impact on the wrist. The watch simply looks more substantial. More so, the increase in diameter also provides Patek Philippe with ample room to introduce Breguet numerals on the dial. The result is a stunning, classical looking perpetual calendar, yet in a more contemporary size.
The fact that Patek Philippe carried over caliber 240 Q to reference 5327 has a good reason, as it remains one of the benchmark movements in the world of Haute Horlogerie. It started its career in 1977 when the base movement, ultra slim caliber 240, was first introduced in the Golden Ellipse. In 1985 the perpetual calendar version, caliber 240 Q, was released in reference 3940. With a height of only 3.75mm it is incredibly slim for a perpetual calendar movement, yet also very attractive, not only because of its superb finish but also because of the stunning micro-rotor. The fact that the movement has such a long, and distinguished, history, hasn’t kept Patek Philippe from innovating as over the years they improved the going train, fitted it with a Spiromax® balance spring, and a lever and escape wheel in Silinvar®, all aimed at increasing the reliability and precision of the caliber.
This article’s 2017 coverage described yellow-, white- and rose-gold versions of reference 5327. Patek Philippe’s current official product pages list two references: 5327R-001 in rose gold with an ivory lacquered dial, and 5327G-001 in white gold with a blue sunburst dial. Both pages list a 39 mm case and the self-winding Caliber 240 Q.
