Decrypt gold on the watch

Historically, many alchemists have tried to use some means to make cheaper and cheaper gold to make a profit, thus accumulating the different textures and colors of gold after adding different elements.

Unlike standard 18K gold, the 18K pink gold, which is slightly red in color, has a different name for red gold, rose gold, etc., and because it used to be popular in the early 19th century Russia has the name of Russian gold. Its composition is roughly 750 ‰ of pure gold with 250 ‰ of electrolytic copper, with ductility, high hardness, not easy to deform or scratch and color change and so on. The latter is especially due to changes in the composition of the alloy if you add silver, the color will be lighter, the more silver to add, the lighter the red. When the silver content increased to 10%, copper content retreated to about 15%, the color will be more partial or partial pink. Today, people have become accustomed to using different numbers to define changes in their hue 3N powder (consisting of 75% pure gold plus 13% silver plus 12% copper), 4N powder (with 75% pure gold plus 9% silver Plus 16% copper), 5N powder (composition of 75% gold plus 4.5% silver plus 20.5% copper). As you can see, the less silver is added and the more copper, the more the color is redder.

In addition, the most likely cause for misunderstanding is 18K white gold. Although the color is generally difficult to distinguish from stainless steel, platinum, etc., but it is still a 18k gold, but its composition is slightly different. Which accounted for the proportion of pure gold is still 750 ‰, as for the other 250 ‰ of metal, it is often the secret of every home. Vacheron Constantin in 2007 to change the men's watch platinum formula. The more common platinum components are pure gold 75% plus palladium 12.5% ​​plus copper 6% plus silver 4% plus 2.5% nickel and then electroplating rhodium protection, but Vacheron Constantin will increase the proportion of palladium to 15%, this expensive action makes Platinum does not need to be electroplated rhodium can be more shiny, the factory also pointed out that such a formula will increase its strength, not to wear. In fact, the same as 18K white gold, 18K pink gold is also prone to fade phenomenon, so Patek Philippe and Rolex in recent years have promoted their 18K gold powder special formula is the so-called "eternal" do not fade new material, in fact, only the experts To distinguish the color of the differences.

In addition, with the help of modern alloy casting technology, one can also create a completely different 18K gold in texture color. The former, such as Yu Bo material research and development of the new world's first anti-scratch material magic gold. It all started with a whimsical "18K gold that will not be scratched." With a six-month feasibility study, with the help of the EPFL, 18k gold, a new wear-resistant, gold-ceramic combination was finally born. This is a new material never seen before. Only diamonds can leave a real scratch on their surface, distinguishing them from other gold in dark sub-color. The significance of the birth of magic gold is not limited to a material, but opened the door to the advent of many new materials. At present, magic platinum, magic silver, magic aluminum and other materials are actively research process.

The latter, as Lange to commemorate the founder Ferdinando Adolf Lange and launched the 165YearsHomage to FALange Anniversary series of three complex function watches, as distinguished from the traditional limited edition watch, watchmaker Lange think of The method of changing the metal composition, the birth of honey and gold material (Honey Gold) This material is still 18K gold, but the hardness of its hardness exceeds 300 degrees Vickers, to double the hardness of other gold alloys even more than Platinum Its gloss is very unique, the color is far lighter than the average 18K, very long history of the charm of antique watches. According to the manufacturer, the reason for this effect is that manganese and silicon have been added and subjected to high temperature treatment. Without a word, it adds a bit of mystery, as if it was a modern mystery made by some modern alchemists in confined underground chambers, by tinkering with flasks and electric furnaces.

A similar situation and Patek Philippe still adhere to the formula secret 18K blue gold. Whether it is oval 3738, or its classic gold cufflinks, that unfathomable blue brilliant, has attracted the attention of many people, as a reservoir praised Patek Philippe perfect work as a reason. In fact, as long as you find a real expert, people can synthesize brown, gray and even a variety of different colors of black 18K gold to come, but people think that habitual thinking of gold must be yellow, white and red on the rare, blue even more prominent.

Gold without fake, different colors, modern alchemy make the watch more colorful.
