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.

(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.

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

This alloy is unique to the Swatch Group and the first brand to use it for watchmaking is Omega. Sedna â„¢ 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 â„¢ gold's unique rose-red color benefits, in part, from the proper proportions of copper, and palladium ensures the lasting beauty of Sedna â„¢ 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

The Omega Constellation Sedna watch is the first watch made with 18K Sedna â„¢ gold. The patented alloy 18K Sedna â„¢ 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 â„¢ 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

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 is a special kind of gold alloy. Is it something sweet from a bee? This is a rare innovation of 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

In order to celebrate the 200th anniversary of FALange, its founder, in February 2015, the German watch brand Lange released the 1815 limited edition commemorative of the 200th Anniversary of Platinum, followed by the release of Silver Plated Honey at the Watch and Miracle Show in late September 1815 limited edition commemorative.

5Npt Gold - 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.

Magic Gold

Magic Gold is a gold and ceramic composite precious metal jointly developed by Hublot and the Swiss Federal Institute of Technology (EPFL). 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.

Watch: Hublot Big Bang Unico full magic gold

In 2015, at the occasion of the 10th anniversary of HUBLOT Hub Big Bang, Hublot launched the Big Bang Unico Full Magic Gold Watch!
