What is the strap?
Strap is horological the personage inside course of study to fix in the effective part of the wrist watch.
Precious metal material
(1) platinum is a rare and expensive natural pure white metal, is one of the world’s rarest jewelry with precious metals, from year to year supplies only 5% of the gold, has almost twice as much on the strength of the gold, 30 times more rare than the gold. Platinum glossy white, natural pure, purity as high as 90% above, likes nature itself, often wear will not fade. Pt900 said the purity of 90% platinum jewelry, Pt950 said the purity of 95% platinum jewelry.
2) K K Gold is Gold and other metal alloy mixed together, because of its English is Karat Gold, so called K Gold. Precious metal parts, 24 k gold, but gold is not suiOmega Seamaster 300 for making the watch is too soft, must mix the other metals to strengthen hardness, general is given priority to with silver, copper and palladium, but no matter which kind of metal mixture, the proportion of gold were accounted for 75%. As the proportion of gold, silver and copper, can produce five different colour and lustre of material, represented respectively by N copper content of high and low, such as copper content in the highest red gold in 5 N, said the correct statement is white K gold and platinum.
3) between the gold
Made of stainless steel and 18 k gold mutual collocation is applied, present unique double color aesthetic feeling.
4) plated with gold Its for stainless steel watchcase, outsourcing a layer of gold alloy, the mechanical rolling into one whole, with micron as measurement unit, the thickness of 1 micron is 1/1000th of a millimeter. Up to 10 to 15 microns thick, usually only 2 to 3 micron.
5) plating is common in modern watches watchcase adornment method, rise of electroplating technology in the seventy s, due to the plating uniform and firm, than the cost is low and not easy to fall off, plated with gold and have no forging yellow shell color, the possibility of corrosion, so will soon be out of the market.
“Purity of silver, 925 is not the highest purity silver! You can see the domestic instant silver respectively 99.99%, 99.95%, 99.90%, the purity of three types of transactions, these three are too soft, not suiOmega Seamaster 300 for jewelry, with 92.5% of commonly do jewelry is the most suiOmega Seamaster 300 (hardness, ductility, etc.), so 925 can also be called silver. But not really sterling silver.” Silver precious metals is an ancient, is the 18th century and used to watch the most used materials, represents the purity of silver, 925 is the highest purity of silver (not the highest purity, common is 925 – suiOmega Seamaster 300 for jewelry, 975 – for Omega Seamaster 300ware, 990, and more pure). Silver is a kind of active metals, easy to react with sulfur in the air, black oxide, make silver black. Now in Omega Seamaster 300 used cosco is better than gold, the reason is that it is easy to lose luster due to water, moisture and other reasons.

Other metal material
1) copper in the wrist watch, copper is the best of things, it is cheap, and features are easy to processing, it is mainly used in machine, at present most movement is brass alloy splint. Usually, we can see the movement of the color is yellow and white, yellow movement is usually plated titanium oxide, zinc nickel alloy white movement.
2) steel, chromium and nickel compound of pure steel, chromium and nickel compound stainless steel processing is difficult, corrosion resistance and abrasion resistance are better than the former, the surface can also don’t electroplating, plating only do polishing or sand blasting, sand processing, forming the appearance of the effect of different stereoscopic effect.
3) titanium because in all steel watch upsurge, titanium is emerging. Its material is referred to as “air time” metals. What is titanium? Titanium is found in the earth’s crust, and its appearance can be bright, shiny metal, silver or, dark gray powder. Titanium is a kind of lightweight, rigid, heat resistance, cold metal, the surface with a layer of oxide film, can prevent wear and corrosion.
4) tungsten titanium alloy with 1000 mpa pressure will first tungsten carbide and titanium carbide powder pressing into embryos pieces, die casting, and then again at 1450 degrees Celsius in the special furnace high temperature sintering for high density parts, finally through multiple processes after grinding with diamond powder is made from tungsten titanium alloy sparkle, wear-resisting performance is good.
5) tungsten steel high hardness, wear resistance, the exterior line is clear, bright and clean bright, referred to as the “wear-resisting material”. Can use, and steel composite into mouth or strap watchcase circle, grain, increase the shell, the surface abrasion resistance and ornamental. A, (tungsten steel is too heavy)
6) precision ceramic precision ceramic is bright and clean, wear-resisting, not hurt the skin, the main ingredient is zirconia, under the condition of a certain temperature to obtain a good processability, again through the use of advanced processing methods, made into fine watchcase, strap, all sorts of color can also be through a particular way, more show luxuriant nobility.
7) high-tech ceramics will be extremely fine zirconium oxide or titanium carbide powder, the powder with high pressure injection mould, in 1450 degrees centigrade high temperature sintering furnace form is not easy to wear ceramic components; With diamond powder grinding, can make unique luster of high-tech ceramics.
