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.

Sunray

Sunray polishing is a specialized technique used to create mesmerizing light effects on watch dials. It involves engraving a pattern of parallel lines or rays on the dial's surface, which mimic the rays of the sun. These engraved lines serve as a canvas for light to interact, resulting in a captivating and dynamic visual display.

The Polishing Process:
The sunray polishing process requires precision and expertise to achieve the desired effect. Here is a general overview of the typical steps involved:

Engraving the Dial: Using specialized machines, the dial is meticulously engraved with parallel lines or rays. The spacing, depth, and direction of the lines are carefully determined to achieve the desired aesthetic.

Burface Preparation: After engraving, the dial's surface undergoes various preparation stages, including smoothing and polishing to ensure a flawless finish. This step is crucial in enhancing the reflective properties of the dial.

Coating and Finishing: To enhance the visual impact of the sunray effect, a thin layer of lacquer or a metallic coating is applied to the dial's surface. This additional layer contributes to the overall brilliance and depth of the dial's appearance.

Sunray polishing technology provides watchmakers with a versatile tool for creative expression. The play of light and shadow on the engraved lines creates a three-dimensional effect, making the dial come alive when exposed to different lighting conditions. The radiance and depth add a touch of sophistication and elegance to the timepiece, making it visually captivating from every angle.

Application and Popularity:
Sunray polishing has gained significant popularity among both luxury and mainstream watch brands. It offers an opportunity to elevate the visual appeal of the dial, making it a sought-after choice for timepieces across various styles and price ranges. Whether it's a classic dress watch or a sporty chronograph, sunray polishing adds an element of visual interest that catches the eye.
Sunray polishing technology has revolutionized the watchmaking industry by introducing a captivating visual element to watch dials. Through meticulous engraving, surface preparation, and coatings, watchmakers achieve stunning light effects that elevate the aesthetics of timepieces. As this technique evolves and combines with other decorative processes, we can expect even more breathtaking creations in the world of watches, captivating enthusiasts and collectors alike.
