As a professional diver’s watch, Rolex is willing to uses gold and other precious metal on its Submariner series. In 2017 Basel, Rolex published several new models, but I always think that those Submariner models they published before are the most classic ones, like 116610LN Black Submariner, 114060 No Date model, etc. Today, the 116613 is for Rolex fans who love two tone style. The replica Rolex Submariner 116613 is made by Noob factory, it is V7 version, absolutely the best one currently. Every detail is replicated to be closer to genuine Submariner watch. Especially the yellow gold coating on bezel and bracelet, it is 18K wrapped gold, not plated, so the gold coating will be more durable and not fade. The case is measured to be 40mm in diameter, 13mm in thickness, which is the same as genuine. Case is brushed 316L stainless steel, while the bezel tooth and crown are 18K wrapped gold. Black ceramic bezel insert features engraved yellow gold markers, the bezel is anti-clockwise rotating. Real black ceramic is used to made the bezel insert, is is more scratch resistant than plastic. Black dial echoes with the black bezel, all hour markers feature yellow gold frame and are filled with white luminous material in the centre, plus hands, they will emit blue light in the dark. Like real Submariner, the innver bezel features correct ROLEX Rehaut.
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.
