The green-tinted sapphire crystal fitted to the reference 116400GV Milgauss has quickly become one of the defining characteristics of Rolex’s anti-magnetic line of watches. The Rolex Milgauss was first introduced in 1956; however, it was not until 2007 that it received its now-signature, green sapphire crystal – an exclusive feature that was originally introduced as a way for Rolex to celebrate the 50th anniversary of their Milgauss line.No other watch in Rolex’s current catalog is fitted with a green-tinted (or any other color) sapphire crystal. However, at the present time, all Milgauss watches that are currently in production leave the factory with green sapphire crystals. Rather than simply being a layer or coating, the light green tint is present throughout the entire material of the crystal, and will not fade or discolor after prolonged wear and use.Rolex claims that it took them many years of research and development to master and perfect the secret procedure of manufacturing their green-tinted sapphire crystals and that the actual process of producing the crystals takes multiple weeks. What is most interesting is that despite a usual eagerness to patent their various in-house technologies, Rolex claims that the green sapphire crystal in the Milgauss is “not patented, as it is so difficult to make that no one else would even venture to try.”Rolex will never reveal their exact formulas and secrets about how they manufacture the green-tinted sapphire crystals fitted to the Milgauss; however, we do know some general information about green-colored synthetic sapphire and the production of sapphire watch crystals as a whole.There are a number of different ways to produce synthetic sapphire, all of which fall into the following general methods of production: melt growth, solution growth, and high-temperature/high-pressure growth. It is hypothesized that Rolex uses a hydrothermal method of production for its synthetic sapphire crystals, which is slow, expensive, and uses heat and pressure to imitate the conditions present deep inside the earth that is responsible for the production of naturally-occurring crystalline gemstones.

Rolex released the first Yacht-Master watch in 2007, and then released Yacht-Master II on the Basel in 2013 which became one of the most classic sporty watch in the market. Of course, then there came out many replica versions, I have seen many editions of replica Rolex Yatch-Master II, but today I would like to introduce a good edition to you, comparing to other editions on the look and function, this is the best.Rolex Yacht-Master Watch design comes from yacht racing, which we can tell from its name. This replica has a 1:1 proportion case, 44mm*14mm is a perfect size for its design.

These functions can be adjusted by the crown and buttons on the side, very easy to operate. There is a small red triangle hand on the dial, this is just for decoration, not moving at all. The blue bezel inspiration comes from the ocean where the yacht should be, and it can rotate both ways. Bezel is made of ceramic, new and top material in watch.
On white dial, all functions of the watch are shown on front of your eyes. At 12 o’clock, there is an annual calendar window displaying month, date and week. The small dial at 3 o’clock is a 7-day power reserve indicator, it is showing the remaining power reserve energy of the replica watch, like genuine Portuguese Annual Calendar watch, the power reserve hand of the replica is functional. Although the replica does not have a real 7-day power reserve capacity, it can provide you two-day timing with one full winding.
