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.

Glossary

Caliber

Caliber, is a term that describes the engine of a mechanical watch, through a reference number for each watch, and this number indicates the size and shape of the watch movement, and is also used to identify the origin of the watch or its maker.


Each watch manufacturer or brand typically has its own set of calibers, which may vary in terms of design, complexity, and features.

Calibers can be categorized into different types, such as manual-winding calibers that require manual winding of the crown to keep the watch running, or automatic calibers that use a rotor to automatically wind the mainspring through the movement of the wearer's wrist. There are also quartz calibers, which are powered by a battery and utilize electronic circuits to regulate timekeeping.

The caliber number or code is often assigned by the manufacturer to identify a particular movement or model. It helps watchmakers, collectors, and enthusiasts differentiate between different watch models and understand the technical specifications and features of a specific watch.
