Rolex green glass cannot be imitated by other brands. What is unique about the process?

Rolex has a unique series "Ge Magnetic Series", including lightning needle and green crystal glass. It is of course called "lightning needle green glass". When it was first introduced, it was difficult to find a product like fried food. At one time, it soared to 10 W, and even the black one reached the hype price of 67 w. Because of its high recognition, Milgauss left a deep impression on his cousins, many of whom were friendly and curious.

1) uniqueness of green glass

The design and manufacture of "green glass" is very unique. Rolex didn't even patent this technology. Rolex claims that because the crystal mirror of green glass is too complicated, other brands can't consider plagiarism. Indeed, the reason why Rolex's green glass can't be copied by other brands is that the overall design of Rolex watch uses a layer of green film on the side of the mirror, which makes the whole mirror stand out from the bezel and makes the whole dial full of green by the refraction of the side. Looking at the surface (front) at 90 degrees, you won't notice the green color, but from the side, there will be a green line on the edge of the glass, which many watches can't copy. Simply put, other watches don't have this height.

2) The lightning rod has high diamagnetism.

The biggest advantage of lightning needle is its high antimagnetic degree, reaching 1000 gauss. It is equipped with an escape wheel made of antimagnetic hairspring and paramagnetic material. The movement uses cal.365,438+0, which is anti-magnetic. Rolex also uses a layer of "golden bell jar" anti-magnetic protection, and uses a case called "faraday cage". That is to say, the second layer back cover is added with anti-magnetism, and the professional anti-magnetism cover is covered under the movement panel, which is the mystery of lightning needle anti-magnetism.

Summary of tips: Although Rolex's green glass is not patented, other brands don't imitate it not because the old technology is superb, but because other brands no longer use anti-magnetic covers to prevent magnetism. (Backward technology) For example, Omega's coaxial Zhizhen movement is antimagnetic, and its technology is far ahead of the double-layer back cover technology in the 1950s. The uniqueness of green glass lies in the old and unique mirror design. If you change a watch, you won't have this green light. What do you think of green glass? Please leave a message to share.
