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.
Part of the brand’s collection since 1945, the Rolex Datejust is the ultimate everyday luxury watch. While the model comes in a vast assortment of styles including different sizes, metals, bracelets, bezels, and dial designs, what remains constant across all Datejust watches is its time and date functionality. The hour, minute, and seconds hands are always placed at the center while the date window is always found at the 3 o’clock position. In true Rolex fashion, the Datejust watch is easy to use and operate but there are a few things to keep in mind when setting the time and date. Read on for our quick guide on how to set the date and time on a Rolex Datejust.Earlier models of the Rolex Datejust did not yet have the quickset date feature. A quickset date feature means that the date can be set independently from the timekeeping hands. Conversely, on a non-quickset Datejust, the minute and hour hands have to be advanced past midnight to change the numeral in the date window.Rolex introduced the quickset date function to the Datejust lineup in 1977 with the introduction of Caliber 3035 movement. So if your Datejust was made in 1977 or later and is powered by Caliber 3035 or subsequent movements (Cal. 3135, 3136, or 3235) then it has the quickset feature.Regardless of when a Datejust was produced, they all come equipped with a screw-down winding crown to ensure the watch’s water resistance. Therefore, a Rolex winding crown must be unscrewed first before any adjustments can be made.
Other Submariners do not have engravings on case back. From the case back, you can see the pins that connect the case and bracelet, they are crafted to be better so that could firmly connect case head, every piece of the bracelet link is made of solid 316L stainless steel, holding the replica is like wearing a genuine Rolex.In a word, the replica inherits all advantages of Noob 116610 LN Submariner but has its own unique features.This is another great vintage project in the replica watch market, which comes with a replica Rolex Submariner. The replica is manufactured by the same factory as Daytona 6214. I have introduced several pieces of replica watches including Panerai and Rolex in my blog, many of them attracted a lot of readers here and they asked me the price, I have to tell them these vintage watches are all sold at reasonable prices. Ref. 5510 should have be the oldest Submariner model Rolex made, it already had the features of modern Rolex Submariner like Mercedes-Benz hands and rotating bezel, however Submariner 5510 also has the iconic features of its own. Here I will introduce the replica to let you know more about those vintage Rolex watches made in old times.The most outstanding place that also makes the watch full of vintage style lies in its dial, which is black. The hour markers of 3-6-9 and bar-shaped also make it different from other Submariner watches. These hour markers are all applied with yellowish luminescence, so are the hands. The dial printings are also in yellow color except the words “200m = 660ft”. Next to the hour markers, there is a circle of minutes scales in track style, which is also different from modern Submariner watch. We actually call such dial “Explorer Style”. The bezel insert is black and features white printings, there is a pearl at 12 o’clock in red triangle background.
