Myths about the "Gold" table Myths about the "Gold" table How is the difference between different "gold" watches? The passage of ISO8654 today is still based on the Swiss watchmaking industry's 1966 standard for the division of "Gold" alloys. This standard will gold alloy color, from 0N to 5N is divided into six levels. These figures refer to the finished color: 0N and 1N have only 58.5% gold content, and therefore can not be called 18K gold. As for 2N to 5N, which is commonly known as 18K gold, gold content of 75% or more. The highest grade 5N alloy contains almost no silver or contains a very small amount of silver, the finished product will be the more red. According to a more specific compositional criteria, the World Gold Council classifies 18K gold into three color categories: Gold: 75% gold, 15% silver, 10% copper Platinum: 75% gold, 25% platinum or palladium Rose gold: 75% gold, 9.2% silver, 22.2% copper Although all called rose gold, but this rose gold is also different. Watchmakers are also fine-tuning the proportions of the three ingredients (gold, silver and copper) to create their own exclusive formula. Myths about the "Gold" table (Left) Gold: Jacques Douro gold foil carved enamel hour dial 18K gold gold leaf carved watch (Middle) Platinum: Cartier new Cléde Cartier watch series, 18K white gold K gold case (Right) rose gold: BVLGARI Bulgari brand new Papillon Heure Sautante watch (102069) Rose gold and red gold is the same? Strictly speaking, the two are not the same. In addition to the nuances of the most obvious colors, the content and proportion of different types of metals in red and rose gold are also different. Oriental people like gold, but the soft gold is easy to deform and it is easy to wear. Therefore, ancient people began to try adding a small amount of other precious metals in pure gold to increase the hardness of gold. K gold is now a lot of color, gold and other metals in the fusion, as long as the addition of different types of metal, the formation of different colors of gold. For example, the most common red lines nowadays include copper, silver and nickel or palladium added to white, and sterling silver added to green. Red series of K gold jewelry to join the main gold, copper, 75% of the gold by adding 25% of the electrolytic copper is red gold, 18K gold formed under this ratio the color of the red. If you add silver, the color will be lighter, the more silver you add, the lighter the red. When 18K gold, silver content increased to 10%, copper retreated to about 15%, the color will be more partial powder, it has become a rose gold. So, in fact, red gold should look more red than rose gold. Myths about the "Gold" table Rose gold: PIAGET ALTIPLANO gold guillines decoration watch, 18K rose gold case. Red Gold: IWC Parkido Fino hand-wound single-button chronograph watch, 18K red gold case. In addition to the common "four gold" (gold, rose gold, platinum, red gold), what are the "new gold"? Sedna gold Sedna gold Omega Constellation series Zorpia watch This alloy is unique to the Swatch Group, the first brand it is used for watchmaking is Omega. Sedna ™ Gold is a new Omega named alloy that is made of three metallic elements, gold, copper and palladium. This is a 18K rose gold, the minimum content of gold is 75%. Sedna ™ gold's unique rose-red color benefits, in part, from the proper proportions of copper, and palladium ensures the lasting beauty of Sedna ™ gold-reddish colors. The new alloy comes from the name Neptune, the astronomer called Sedna, and Sedna is considered to be one of the most color-shaded objects in the solar system. In addition, Sedna is also the name of a goddess living in the bottom of the Arctic Ocean in the legend of Inuit. Omega constellation series Sedna watch Omega constellation series Sedna watch The Omega Constellation Sedna watch is the first watch made with 18K Sedna ™ gold. The patented alloy 18K Sedna ™ gold from a fusion of gold, copper and palladium ensures the case's unique rose gold color lasts forever. Hour markers, hands and clasps are also made of 18K Sedna ™ gold. The luxurious silver "dial" dial inspired by the first constellation watch in 1952, made of high-quality brown leather. The watch is equipped with Omega's innovative Si14 silicon balance wheel hairspring and the revolutionary Omega 8501 coaxial movement, clearly visible through sapphire backs. The Omega Constellation Sedna watch is water resistant to 10 atmospheres (100 meters / 330 feet). The limited edition 1,952 pieces of the Omega constellation Sedna watch were commemorated in 1952 as the birth of the famous constellation Omega watch. Omega constellation series supremacy watch Omega constellation series supremacy watch Zumba watches adhering to the Omega watchmaking concept, the internal carrying the most advanced mechanical movement brand, inspired by the design of the constellation series earlier models. Each watch has undergone a series of independent testing and certification. Zunpa watch the two most distinctive design is the dial and bezel. Dial design style has long been called collectors watch collection, grooved bezel has been decorated in a variety of famous constellation above the watch design elements. Premier watch engraved on the back of the badge engraved with the Observatory held a precise time trial dome screen. The eight stars above the Observatory symbolize the most important precision record Omega has created, and they also symbolize the eight test standards that must be passed to certify the Astronomical Observatory issued by the Swiss Federal Institute of Metrology (METAS). Honey gold Honey gold Honey gold is a special kind of gold alloy. Is it something sweet like from a bee? It's a rare innovation in a fun metal, 18k gold family. The alloy was developed in cooperation with a university by Lange and applied for a patent. Honey is still a gold color 18K gold, with 75% of the gold element, first look at the color between gold and rose gold, some white but the tone is warm. This alloy is said to contain a small amount of silicon for luster and higher hardness with a Vickers hardness of 300HVI (160HVI for 18k gold, 190HVI for rose gold and 135HVI for 950 platinum). Watch: Lange's 18th anniversary of the 1815 honey gold commemorative models Anniversary of the birth of Lange 1815 gold color gold commemorative models German watch brand Lange to celebrate its founder F. A. The 200th Anniversary of Lange, February 2015 Launched the 1815 limited edition commemorative of the 200th Anniversary of Platinum on Black, followed by the 1815 Limited Anniversary commemorative of Silver Plated Honey at the Watch and Miracle Show in late September. Although the material is very different from the platinum case, but its size is exactly the same, are 40mm diameter, bezel outer rim and the shell has a small step --- It seems that this will slowly become the appearance of the 1815 series It's The disk design is still the classic 1815 features: small three-pin layout, the outermost track track scale, Arabic numerals. But the face plate is slightly different, the original 1815 dial surface smooth and delicate, and the new honey gold 1815 limited edition silver disc is very interesting, with a vintage sailing chronometer silver dial texture particles. Honey Gold 1815 200 anniversary of the limited edition of 200 pieces, the retail price of 33,500 US dollars, or € 31,500, the price with the same as the beginning of the limited edition of platinum. 5Npt Gold - Panerai Panerai Panerai watches use this nearly 5Npt alloy copper content of nearly one quarter (24.1%), in addition Panerai also added a small amount of platinum in the formula (0.4%), used to prevent oxidation of the alloy.

This unique 18K synthetic gold with unprecedented wear resistance, effective solution to the senior watch metal surface in the production, processing and wear of the widespread process of scratches and scratches, called "the world's most hard Gold. " Magical Gold is amazingly wear-resistant because it can withstand compressions of up to 1,000 Vickers, far outperforming standard Vickers hardness of 18K gold or 600 Vickers hardened steel up to 400 Vickers. This means that only diamonds with a Vickers hardness of 2,000 leave so-called scratches on their surface.
