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.

Telemeter

Telemeter

Is a feature found in some watches that allows the user to measure the distance between the watch and a visible or audible event. It is typically used to determine the distance of a lightning strike or other events. For example, the chronograph hand is activated upon seeing the lightning and stopped upon hearing the thunder.

The Telemeter scale is usually placed on the outer edge of the watch dial or on a subdial. It works based on the principle of sound transmission through the air at a known speed. When observing the event, such as a lightning flash, the wearer starts the chronograph function. The wearer stops using the chronograph when hearing the sound of the event, such as thunder. By reading the corresponding point on the Telemeter scale where the chronograph hand stopped, the user can approximate the distance of the event.
