The New Patek Philippe Twenty~4 7340/1R Perpetual Calendar

Introduced in 1999, the Twenty~4 collection was Patek Philippe’s first dedicated line of feminine timepieces. The original model featured an Art Deco-inspired manchette (cuff) design, but in 2018, the brand unveiled the Twenty~4 Automatic, which is a round-cased iteration powered by an automatic movement. This year, Patek Philippe elevates the collection further by introducing a perpetual calendar complication, marking the collection's debut in the realm of Grand Complications.
Crafted entirely in 18K rose gold, the watch features a 36mm case with a slender profile of just 9.95mm, making it sit gracefully on the wrist. The case is meticulously finished with a combination of polished and brushed surfaces, enhancing its refined aesthetic. Two dial options are available. The Ref. 7340/1R-001 features a silvery opaline dial with a vertical satin finish, evoking the texture of shantung silk that feature irregular texture, while the Ref. 7340/1R-010 presents an olive green sunburst dial for a more contemporary appeal.

Remontoire

The word remontoire comes from the French word “remonter“, meaning “to wind”, and it is a secondary, smaller spring used to apply power to the balance and escapement mechanism of a timepiece. The remontoire itself is then periodically re-wound by the power from the mainspring. It serves to stabilize the drive force transmitted to the escapement and compensates for variations in the geartrain's friction. It ensures accuracy by managing the power distribution throughout the clock.

There are different types of remontoires, including gravity remontoires and spring remontoires. Gravity remontoires counteract fluctuations in force caused by the mainspring winding down, while spring remontoires utilize a spring as their power source.

Remontoires are designed to rewind periodically, ensuring long-term accuracy by averaging out rate variations. The concept of a remontoire is not new, with historical roots dating back to Swiss clockmaker Jost Burgi in 1595, who invented the gravity remontoire, and English clockmaker John Harrison in 1739, who created the spring remontoire.
