If you think that gold is just a precious metal watch, you are not satisfied.

Perhaps it is the limited production of gold and the oldest currency in circulation. The production of coins, jewellery and watch works in gold has also become a valuable value-preserving item from the past to the present.

In the 2600 BC Egyptian hieroglyphics, there was already a description of "Golden". It is said that the Egyptian king of Mitanni, Tushrata, claimed that there are more gold mines in Egypt than in the mud.

Gold is the oldest currency in history. In the sixth century BC, gold was used by humans in the form of money. It is said that during the period from the sixth century to the fifth century BC, the currency that was circulated in Chu State and was called 郢爰 was built with gold. The ancient Egyptians developed the dewaxing casting method as early as 1200 BC to make a variety of gold masks and jewelry.

â–³ Ancient Egyptians are good at using gold to create gold foil, and will synthesize other metals to change the hardness and color of gold.

In the first century BC, it was the beginning of the rise of ancient Roman civilization, when the ancient Romans developed a large amount of gold mining in the form of water conservancy mining. According to reports, global gold production in 2017 reached an innovation of 3,269 tons, but due to the decline in recycled gold production, the annual gold supply fell by 4%. The latest data shows that the total amount of gold in the world is 171,300 tons, and the estimated total global supply is 205,000 tons. Some people predict that the world's gold will be mined in 2025.

â–³ Gold is the longest-running and popular metal of value. It is expected that global gold will be mined soon.

Perhaps it is the limited production of gold and the oldest currency in circulation. The production of coins, jewellery and watch works in gold has become a common value-preserving item from the past to the present. The case is made of yellow K gold. Watchmaking, while Huang Kjin is mixed with different metals in pure gold to present different shades. The most common is to add copper to form what we call red gold or rose gold. The alloy of 14K or 18K gold added to silver appears yellow-green, which is called green gold; and gold added to palladium or nickel (now replaced by other metals) becomes platinum. However, these precious metals such as gold, rose gold and platinum, which we are familiar with, can no longer satisfy the refined watch industry. Now, based on these precious metal materials, the physical properties of precious metals are improved by the method of making or adding alloy components. Common in some watch brands with strong research and development capabilities.

â–³ Gold is one of the main manufacturing materials for watch cases. When gold is added to different metal components, it becomes a precious metal such as rose gold and platinum.

The most famous Rolex eternal rose gold retains the color of rose gold, but it strengthens its non-oxidizing color, and the color is perfect and never fades. The secret is that it is slightly higher under the adjustment of pure gold to copper. In 2 percent of platinum, this patented eternal rose gold has become one of Rolex's most popular watch materials.

â–³ Rolex's patented eternal rose gold material is added to platinum gold to keep its color stable. In 2018, Rolex's new Rainbow Radio chronograph watch case is made of eternal rose gold.

The addition of other precious metals produces gold materials that enhance physical properties, as well as the 18K Sedna gold developed by Omega. Like the Rolex Eternal Rose Gold, it emphasizes its vibrant red color and long-lasting brilliance. The 18K Sedna gold is pure gold in rose gold. After the proportion of copper has been adjusted, palladium metal has been added to achieve the characteristics of long-lasting color tone. Omega 18K Sedna gold has also been patented. Like Rolex, it has the same technology and equipment in the factory. Omega can have such advantages to create fascinating 18K Sedna Gold.

â–³ Omega's exclusive Sedna gold is made of palladium metal added to the rose gold to give it a stable and long-lasting color.

Rolex's eternal rose gold and Omega's 18K Sedna gold are difficult to distinguish at the level of color, purely subjective preference, I think Omega's 18K Sedna gold color is more red gold, and Rolex's eternal rose gold The rose is pink more.

â–³ Omega has developed the exclusive Sedna gold from the factory. The color is more red than that of rose gold. It has been used in a large number of models. This picture shows the Omega Speedmaster series timing to the Observatory.

However, in the experiment of gold material, Omega is not only a special research and development of 18K Sedna gold, but its patented Ceragold porcelain gold is processed by mechanical finishing of the fired ceramic bezel, and then engraved with a high-performance laser. Preset the scale and time scale on the circle, then add a conductive layer to the surface of the finished ceramic bezel and the mark groove, introduce 18K gold and pass the similar plating effect to make the 18K gold implant grow on the ceramic watch. On the circle, finally put it into the gold electrolytic cell for 48 hours. At this time, the whole bezel is covered with a layer of 18K gold thickly. After the final cleaning and polishing, it becomes 18K gold perfectly deep in the bezel scale. Ceragold porcelain gold. Strictly speaking, Omega's Ceragold porcelain gold is not a metal, but a special process that combines ceramic and gold.

â–³ Omega Ceragold porcelain gold technology is a seamless combination of ceramic and gold, the first process to decorate 18K gold on ceramic parts.

â–³ Omega Ocean Universe 600m 45.5mm coaxial chronograph bezel is made of Omega's original Ceragold technology.

The rose gold case can be used in different processing and alloy formula adjustments, and can be used in different color levels. Some people prefer a more golden color, while others prefer a more intense red gold, but all the rose gold case. In addition to smooth surface polishing or matte brushing and polishing, there are almost no other surface effects. Bucari's Octo Finissimo automatic sandblasting watch, published in 2018, is based on rose gold and sprayed with rose gold powder. Sand treatment on the surface, so that the overall case and chain material looks like the sand of the desert is covered, I personally feel that Bulgari should name the material of this watch as desert cream pink gold. With a matte finish and a subtle sandblasting effect, the Octo Finissimo sandblasted automatic watch has an ultra-thin overall case and chain strap, like a men's special rose gold bracelet, hoarse and calm, yet bold and bold. The focus is on wearing a suit and not wearing a cuff. The Octo Finissimo sandblasted automatic watch allows Bulgari to have a signature design on the precious metal.

â–³ Bulgari's new Octo Finissimo ultra-thin self-winding watch, launched in 2018, uses sand blasting technology to create a unique surface texture of rose gold.

As a high-end traditional watch brand, Audemars Piguet has dominated the martial arts for more than 40 years with the Royal Oak. The Royal Oak, which is full of gold material, is also the ultimate style of many fans. However, after the launch of the exclusive Frost Gold Royal Oak, I believe many people turn to the pomegranate skirt of the Royal Golden Oak. In 2017, to celebrate the 40th anniversary of the Royal Oak Women's Watch, Audemars Piguet and the Italian Florence designer Carolina Bucci Caroline. Bucci cooperates with the Italian ancient handicrafts on the rose gold and white gold case and chain belt, and carefully and manually hammers the workmanship to create a decorative effect like frosting, just like in the Swiss mountains. Winter specialties: white snow, snow and ice like a crystal melted in the hands, sparkling.

â–³ Audemars Piguet's Frost Gold Royal Oak watch was decorated with ancient craftsmanship in 2017.

This technique uses a diamond-tipped hammer to carefully hammer and hammer on the precious metal to form a fine dent on the surface, just like a gemstone that perfectly cuts different cuts. It will give off a flashing light and shadow, which is mistaken for a model with a fine diamond.

â–³ Audemars Piguet's Frost Gold effect is a tool that taps the surface of the case, and the light reflected by the groove makes the watch look like a diamond.

The launch of Frost Gold attracted a large number of fans, but this batch of frost gold Royal Oak models only 37 mm (automatic movement) and 33 mm (quartz movement) style, so many men who like this injury Through the heart. Look at the Frost Gold Royal Oak watch, the effect of its delicate hammering cream, under the sharp lines unique to all Royal Oaks, impeccable and impeccably at every detail and the point of the turning point, impeccable Any problem, it has become a jewellery-grade watch. The use of gold in the case, as well as these fascinating and diverse creations, will also be raised to the collection of crafts and jewellery grades, which were originally pure gold with pure monetary value.

â–³ Audemars Piguet Gold Royal Oak watch is available in different sizes from rose gold and white gold, each with a 37mm automatic style (left) and a 33mm model with a quartz movement.
