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.

Hertz (Hz)

Hertz (Hz)

Is a unit of measurement for frequency, representing the number of cycles or oscillations per second. This unit is used to describe the frequency of a watch's movement or the vibrations of a balance wheel.

Traditional mechanical watches typically operate at frequencies ranging from 2.5 to 4 Hz, which means the balance wheel completes 2.5 to 4 oscillations per second. This frequency is sometimes referred to as "beats per hour" or "vibrations per hour," indicating the number of oscillations the watch's movement performs in one hour. On the other hand, modern high-frequency watches, such as those equipped with quartz movements or certain mechanical movements, can operate at much higher frequencies. For example, quartz watches typically operate at a frequency of 32,768 Hz, making them more accurate in timekeeping.
