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.

Glossary

Safety roller

A crucial component that prevents the escapement from unlocking accidentally when the watch experiences sudden shocks or forces while the impulse jewel is disengaged from the pallet fork. It acts as a protective mechanism, ensuring that the escapement remains locked even during unexpected impacts, thereby preserving the watch's accuracy and reliability. By preventing premature unlocking, the safety roller contributes to the stable and precise movement of the watch's hands, maintaining its overall timekeeping performance.
