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

oscillator

 An oscillator refers to a key component of the watch's timekeeping mechanism that generates a regular and precise oscillation or vibration. The oscillator is responsible for providing the reference frequency or beat rate, which determines the accuracy of the watch's timekeeping.


Traditionally, mechanical watches utilize a balance wheel and hairspring as the oscillator. The balance wheel is a weighted wheel that swings back and forth, while the hairspring acts as a restoring force, regulating the speed of the balance wheel's oscillations. The balance wheel and hairspring assembly is often referred to as the balance wheel system.

In modern quartz watches, an electronic oscillator called a quartz crystal resonator is used. A tiny piece of quartz crystal is cut and shaped to vibrate at a precise frequency when an electric current is applied. These vibrations are converted into electrical signals and used to regulate the timekeeping of the watch.

In both mechanical and quartz watches, the oscillator's regular oscillations provide the basic unit of time measurement, which is divided into increments to display the hours, minutes, and seconds. The accuracy of the oscillator determines the watch's ability to keep time reliably, with higher frequency oscillators generally associated with increased precision.
