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.

Power Reserve

Power Reserve

Also known as a remaining power indicator, the power reserve is an indicator that shows the amount of remaining energy in a watch. It indicates the duration of the watch's operation after the main power source, such as manual winding or automatic self-winding, stops. The remaining power is displayed through a sub-dial, an indicator on the main dial, or through dedicated markings, with the display method varying from watch to watch.

The remaining power is usually expressed in units of time, such as hours or days. The duration of the power reserve varies from watch to watch and depends on several factors, such as the type of operating mechanism, the size of the movement, the type of power source, and the functions present in the watch. The power reserve capacity can range from several hours to several days.
