Patek Philippe caliber 26‑330 S C

The Patek Philippe calibre 26-330 S C is a self-winding movement displaying central hours, minutes, and sweep seconds together with a date in an aperture. It also incorporates a stop-seconds function, allowing the time to be set precisely to the second. The movement measures 27 mm in diameter and 3.32 mm in thickness. It consists of 207 parts, uses 30 jewels, and is wound by a 21K gold central rotor. It operates at 28,800 semi-oscillations per hour and offers a power reserve ranging from a minimum of 35 hours to a maximum of 45 hours. Its regulating organs include a Gyromax balance and a Spiromax balance spring, and the movement bears the Patek Philippe Seal. Within Patek Philippe’s current movement range, calibre 26-330 S C is used as a self-winding base for time-and-date watches with central sweep seconds.
