324 S C

About the Patek Philippe 324 S C

It descends from the 315 of the 1990s and was introduced around 2004, with 213 parts, 29 jewels, a 21-carat gold central rotor, a Gyromax balance and a beat of 28,800 vph for a 45-hour reserve, at 27 mm across and 3.3 mm high. From the late 2000s it received the Spiromax silicon balance spring, and since 2009 it has carried the Patek Philippe Seal in place of the Geneva Seal. It is the maison's everyday automatic, as the micro-rotor 240 is its thin one; the 240 piece explains that division.

In the library it sits under 31 Nautilus references, the 5711 and the 7118 ladies' model, 16 Calatravas, the 5227 with its hinged caseback and the 5296, 14 Aquanauts, the 5167 and 5168, and 7 Twenty~4 Automatics. The 40 mm case accounts for 21 references and the 35.2 mm Nautilus for 10. Five are limited editions.

The 26-330 S C of 2019 is its successor, with a stop-seconds function and an anti-backlash reduction wheel, and the 324 S QA LU is the annual calendar built on the same base.
