Sapphire watch glass in what circumstances are easy to be wear
Abstract：In addition, there is sharp strokes to rub on the surface of the glass, also easy to cause scratches, this depends on row ceng strength and speed, the contact point is sharp, the greater the speed and power, the more likely it is to be scratched
Used to watch seldom useful sapphire watch glass, and now most of the watches are adopted the sapphire glass. Do have great benefits for table glass, sapphire is not easy to scratches and wear, because of its hardness is 9, second only to diamond.
Sapphire glass also will be wear and tear, early rado once in the AD says it is "never wear" watches, is clearly exaggerated, later changed to wear resistance, that's more like it. Indeed sapphire glass just wear resistance, whatever something hard, often are brittle, so sapphire glass under the intense collision, rupture, or crack easily. (see photo)
In addition, there is sharp strokes to rub on the surface of the glass, also easy to cause scratches, this depends on row ceng strength and speed, the contact point is sharp, the greater the speed and power, the more likely it is to be scratched. There is glass mechanical point of view, stress Angle of about 45 degrees, more easily cause larger Nick.
Early (80 s), the Swiss rado manufacturers to come to China to sell its tungsten steel watchcase, sapphire watch glass, live to do performance; Will watch on the ground and under the glass face, and then step on one foot, a watch on the ground was pinned under friction back and forth, leather shoes, after the experiment, wipe off the watch, incredibly watchcase, table glass is intact, still so if brightness is new.
People present at all surprised, had never seen such a strong anti-wear of watches, all think that's amazing. In retrospect, I feel it's a gimmick, suspected Yu Liuqian magic show, actually this is a simple physical pressure of common sense, the problem is that the glass and the contact area of the ground is too big, foot pressure and friction speed can be control by people.
I also take rado, is arch type drill star, has to wear about 15 years, my sapphire watch glass on the edge of the edges, bristles with pit, defects, counter, form the side of the glass is not easy to wear, I want to wear mainly because watches and table surface scratch a larger opportunity. As radar watch sapphire glass surface is whole appearance, is prominent, the most vulnerable to damage its edges. (see photo) around the glass are embedded into the watch case, relative safety.
Sapphire watch glass but caused by wear or scratch, can't through the fine polishing to remove, can't fix that is to say, can only change new, better flat circular glass replacement, if or special-shaped arch, it basically looking for original accessories, costs are not cheap.
