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.

Open-work

Open-work

Is a decorative process where a watch is stripped down to expose the intricate internal mechanisms of its movement. This involves reducing the size of the dial or completely removing it, as well as hollowing out the plates, bridges, and other components to reveal the gears, balance wheel, and other parts. Additionally, the watch hands may be designed with a small center portion that secures and moves the hands. Openwork watches showcase the beauty of the mechanical movement, allowing users to see the intricate mechanisms and the interaction of gears and different parts of the watch movement.

The difference between an openwork watch and a skeleton watch:

Both designs showcase the watch movement, but an openwork watch allows users to see most of the movement and its different mechanisms. This is achieved through hollowed-out plates and bridges that highlight the gears, balance wheel, and various delicate parts of the movement. On the other hand, a skeleton watch does not have hollowed-out plates and bridges, which means users cannot see the intricate parts of the movement such as gears and the balance wheel.
