For HUAWEI WATCH GT 2 GT2 GT3 Pro 46mm Smart Watch Strap

The silica watch belt is made of 100% natural solid silicone rubber by the oil press; The watch belt itself has a certain tension and softness, so it is easy to deformation and immediately recover; Silica watch belt with wear resistance, high temperature resistance, no deformation, non-toxic, tasteless, no side effects to the human body and soft, no cracking, long service life, does not stimulate the skin and other advantages, silica watch belt is a real green environmental protection accessories.
In recent years, people began to put some functional materials, such as negative ions, germanium, titanium, far infrared and so on into the raw materials of silica watch belt processing, is that it has a certain health function. Such as silica energy scale, silica anion table is the use of the negative ions and other elements added to the silica material together with the processing of silica watch band. Watchband, is the effective part of the watch fixed wrist collectively. There are a variety of watchband materials, cowhide is the most common one, and crocodile is the most precious one, crocodile watchband is also known as the "platinum" leather watchband. Platinum is a rare and expensive natural pure white metal, is one of the world's rarest jewelry precious metals, the annual supply is only 5% of gold, has almost twice the strength of gold, 30 times rarer than gold. Platinum luster white, natural pure, purity of more than 90%, natural, often wear will not fade. Pt900 means 90% pure platinum jewelry and Pt950 means 95% pure platinum jewelry.
2) K Gold K gold refers to gold and other metals mixed together alloy, because of its English is Karat Gold, so shortened to K gold. For the precious metal part, is 24 karat, but is too soft to be suitable for making watches. Other metals must be mixed to strengthen the hardness. Generally silver, copper and palladium are the main metals, but no matter what kind of metal is mixed, the proportion of is 75%. With the ratio of gold, silver and copper, five kinds of materials with different colors can be produced, and the copper content is denoted by N respectively. For example, red gold with the highest copper content is denoted by 5N, while white gold is correctly referred to as white K-gold.
3) Half gold
It is made of stainless steel and 18K gold material to match each other, presenting a unique two-color aesthetic feeling.
4) Gold its case is stainless steel, outsourcing a layer of gold alloy, through mechanical rolling into the whole, its thickness to micron as a unit of measurement, 1 micron is equal to 1/1000 mm. Up to 10 to 15 microns thick, usually only 2 to 3 microns.
5) Electroplating (gold plating, thanks to wiiasa brother, electroplating should be placed in the precious metal properties, the opening of the following explanation) electroplating is a common case decoration method in modern watches, electroplating technology rose in the 1970s, because of uniform and firm electroplating, lower than the cost of gold and not easy to fall off, and no yellow shell discoloration, corrosion may soon be eliminated from the market.
6) Silver "In terms of silver purity, 925 is not the highest purity of silver! You can see that the domestic instant silver prices are 99.99%, 99.95%, 99.90%, three kinds of trading purity respectively. These three kinds are too soft to be suitable for jewelry. Generally, 92.5% is the most suitable for jewelry (hardness, ductility, etc.), so 925 can also be called pure silver. But it's not really sterling silver." Silver is an ancient precious metal, the most commonly used material for pocket watches in the 18th century and before, and 925 represents the purity of silver, the highest purity of silver (not the highest purity, common 925-- for jewelry, 975-- for tableware, 990, and even purest -- court notes). Silver is an active metal that reacts easily with sulfur in the air, creating a black oxide layer that blackens silverware. Now in the application of the table is far less than gold, the reason is that it is easy to lose luster due to water, moisture and other reasons.
