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.

Longitude

Longitude is the angular distance of a specific location on Earth, measured east or west from the Prime Meridian. The Prime Meridian, located at 0 degrees longitude, serves as a reference point from which longitude lines are measured. Longitude lines extend from 180 degrees west to 180 degrees east, forming a complete circle around the Earth.

Longitude plays a crucial role in determining the location between east and west and is used in conjunction with latitude to create accurate geographic coordinates. Measuring longitude is essential for navigation, timekeeping, and precise location determination on maps and Global Positioning Systems (GPS).

Longitude lines also play a significant role in certain watch features that rely on geographic data, such as world time complications or sunrise/sunset indicators.
