The case and buckle are made of real refined steel, which is more durable and corrosion-resistant! Fully automatic machinery, dial 40mm, scratch resistant sapphire glass mirror, anti reflective convex magnifying calendar window, technical masterpiece! Rolex uses unique technology to make two-color cerachrom word circle of Greenwich II. Brands generally use zirconia to make ceramics, but this material does not show the ideal color. Therefore, Rolex has developed a formula using alumina after in-depth research. The color adding part adopts the infiltration method, let half of the word circle be immersed in the compound solution, and burn the color of this part after a high temperature of more than 1600 degrees Celsius! This process must be very careful and accurate, so as to make the tone of the two halves of the word circle clear and distinct. Because the success rate is too low, the finished products are very scarce
