Jewelry Miura Co., Ltd., a Japanese jewelry manufacturer, has launched the world's first mechanical watch featuring a dial made from 18K purple gold via the crowdfunding platform Kickstarter, according to a press release published on desertsun.com.

The introduction of this novel material into the sphere of horology marks a notable development in the application of precious metal alloys for timepieces. This debut, facilitated by a public crowdfunding campaign, brings a patented and officially hallmarked material to the market in the form of a watch dial. The initiative by Jewelry Miura represents a new use for an alloy known for its distinctive coloration and challenging manufacturing properties, applying material science to an industry where aesthetic innovation is highly prized. It demonstrates a focused effort to expand the palette of materials available for luxury watch construction.

What We Know So Far

  • Jewelry Miura Co., Ltd. has launched what it reports is the world's first mechanical watch with an 18K purple gold dial on the Kickstarter platform, according to desertsun.com.
  • The company has reportedly secured patents for its proprietary purple gold production technology in key markets, including Japan, the United States, and Europe.
  • The 18K purple gold used in the watch dials has been officially hallmarked by the Japan Mint, certifying its precious metal content.
  • Purple gold is described as an 18K gold alloy created through the combination of pure gold and aluminum.
  • The material is inherently brittle due to its unique crystalline structure, which prevents it from being processed using conventional metalworking techniques like bending or stretching.

The Innovation Behind Purple Gold Watches

The core of this development lies in the material itself. According to the company's release, purple gold is an 18-karat gold alloy, meaning it is composed of 75% pure gold by mass. Its distinct and vibrant purple hue is not the result of a surface coating or plating process. Instead, the color is an intrinsic property derived from the material's specific crystal structure, which is formed by alloying gold with aluminum. This ensures the color is permanent and will not fade or wear away over time, a critical attribute for materials used in fine jewelry and horology.
