【2017 SIHH Geneva Watch and Fairs】 Audemars Piguet Royal Oak Series Frosted Gold "cream gold" watch
| 【2017 SIHH Geneva Watch and Fairs】 Audemars Piguet Royal Oak Series Frosted Gold "cream gold" watch Tribute to the 40th anniversary of the legendary ladies watch design Audemars Piguet, a Swiss luxury watch brand, presents a new Frosted Gold "cream gold" collection from the Royal Oak Collection, paying tribute to the 40th anniversary of the Royal Oak Collection Ladies Watch. Audemars Piguet and Florence jewelry designer Carolina Bucci, the modern approach to interpretation of the legendary design of the Royal Oak Women's watch, effort to create a bright sparkling platinum and rose gold new watch. In 2016, Audemars Piguet paid tribute to creating extraordinary female designers over the years: In 1976, Jacqueline Dimier re-introduced the 1972 classic originality of Gérald Genta to create the first Royal Oak Collection ladies' watch. Today, Royal Oak Series "cream gold" watch in the unique interpretation of jewelry designer Carolina Bucci come out bright. Royal Oak Series "Cream Gold" watch reflects Audemars Piguet's heritage of high-level jewelry craftsmanship tradition, through the ancient hammering process, also known as Florence craft, to shine bright visual effects. Carolina Bucci modern design with a new interpretation of this ancient craftsmanship by Audemarsts watchmakers into high watchmaking art, perfect for the unique structure of the Royal Oak series case and strap. The unique texture created by the Florentine craft, combined with the drawing and polishing process of the Royal Oak Collection case and strap, has also become an opportunity for both parties to reach a cooperation. Carolina Bucci's workshop uses the Florentine craft to create jewelry that has been decades-old. The workshop uses diamond-top tools to hit the gold, making it a very fine notch on the surface, showing a diamond-like glittering effect. In recent years, Carolina Bucci emphasizes the scrubbing effect in product design, and is widely used in the design of products such as bracelets and pendants. The challenge for Audemars Piguet is to use a matte finish on the case and strap of the Royal Oak watch and to keep this collection of classic, minimalist lines. In addition, watchmakers need to consider the order of polishing and wire drawing processes due to their unique gradient band structure. The craftsmen at Carolina Bucci Workshop and Audemars Piguet conducted months of experimentation to make the surface brighter in the light and to retain the softness and flexibility of the Royal Oak Band. This is a crafted complex process: do not increase one point, not diminished, but make the Royal Oak watch a new look. Audemars Piguet Royal Oak Ladies Watches After 40 years of aging, Audemars Piguet Royal Oak "Cream Gold" watches are designed to highlight Audemars Piguet's ongoing commitment to innovation and to pay tribute to Jacqueline Dimier's classic watches. As one of the few modern women's watch designers, the design style Jacqueline Dimier laid for Aide still affects Audemars Piguet's watch design philosophy. Jacqueline Dimier joined Audemars Piguet in 1975. Her first work is a new interpretation of the Royal Oak Collection by Jerome Zorda as a modern watch for women. Jacqueline Dimier did not undermine the classic tough style of this watch, but in a unique design language to show the rich features of the Royal Oak series, and through the beautiful and harmonious size ratio, to create a more light, rounded appearance. This coincided with the idea of Carolina Bucci, although she and Jacqueline Dimier have different times perspective, but they uphold the Royal Oak Series design philosophy: to highlight the feminine design to create a new watch and keep the Royal Oak Series Classic elements. Today Audemars Piguet blends the classic design of Jacqueline Dimier with the modernist approach of Carolina Bucci, blending modern watchmaking and jewelry making with the new Royal Oak Collection "Cream Gold" - 40 years of baptism, legendary, Long lasting.
