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.

Impulse

Impulse

refers to the push or force required to maintain the oscillation of the balance wheel in a mechanical watch. The balance wheel, along with the hairspring, regulates the accuracy of time display in the watch. The impulse is provided by the escapement mechanism, which interacts with the balance wheel, allowing it to move forward and then releasing it at the right moment for it to swing back (oscillate back and forth).

Watchmakers focus on designing, adjusting, and lubricating the escapement mechanism to improve the impulse and achieve good timekeeping performance.

Quartz watches do not rely on impulse as they use a different mechanism based on the oscillation of a quartz crystal.
