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.

Main Spring Winder

The main spring winder, also known as the mainspring winder or mainspring winder tool, is a tool used in watchmaking to wind and unwind the mainspring of a mechanical watch. It is an essential tool for professional watchmakers and watch repairers, enabling them to efficiently and accurately wind and unwind the mainspring, facilitating the maintenance and repair of mechanical watches.


The mainspring winder consists of a handle or clamp and a set of interchangeable tips or columns of various sizes to accommodate different watch movements. The tips are designed to fit the main barrel arbor of the mainspring and provide a secure grip for winding and unwinding the mainspring.

The use of the mainspring winder requires precision and skill in handling to ensure proper winding or unwinding of the mainspring. It is a delicate process that requires experience and expertise, as improper handling of the mainspring can lead to damage to the watch movement or even injury to the watchmaker.

The mainspring winder ensures proper winding for optimal power transmission and maintains the accuracy of time measurement in the watch.
