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.

Balance Wheel

Balance Wheel

The balance wheel is a weighted wheel that oscillates back and forth thanks to the balance spring, and its main purpose in watches is to regulate and adjust timekeeping.

The balance wheel converts the continuous rotational motion from the balance spring into precise and equal oscillations. The frequency of the balance wheel's oscillations is accurately adjusted to allow the watch to maintain accurate and regular time. As the balance wheel swings back and forth in equal oscillations, it allows the gear mechanism in the watch to advance a specific amount with each oscillation, thereby moving the watch hands forward consistently. Thus, the balance wheel enables the watch to maintain time accuracy by providing a constant and regular regulation of the watch's movement.
