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.

Tachymeter

Tachymeter

Is a gauge that measures the speed of a moving object over a specific distance. It is usually found on the edge of the bezel or the outer rim of the watch dial. It is used to measure speed based on elapsed time. The tachymeter scale is typically marked with units of speed such as kilometers per hour (km/h) or miles per hour (mph).

The timing function starts working like a chronograph and measures the time it takes to travel a certain distance. Then, you can read the speed of the moving object on the tachymeter scale based on the elapsed time. The tachymeter scale is commonly used in sports such as car racing and other activities that rely on speed.
