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.

Gongs

Gongs

Are the thin, coiled metal strips responsible for producing sound in mechanical watches. They are typically made of steel or other alloys with excellent sound-conducting properties. Gongs are shaped in a circular or spiral form and are carefully positioned within the watch movement. When struck by small metal hammers, they vibrate and produce distinct and melodic tones.

Gongs are used in watches that feature complex functions such as minute repeaters or alarm watches. The gongs are carefully designed and tuned to produce subtle and pleasant tones when struck.

The difference between gongs and bells:

Gongs produce a series of tones that differ in pitch and duration, while bell provide only a single tone.
