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.
Sticking with undersea operations, the Oris ProDiver collection is an interesting one, given that Oris is one of the few watch companies that remains actively engaged in dealings with commercial divers. More specifically, Roman Frischknecht is a commercial diver that has been an Oris ambassador for some time, and rather than simply being an ambassador in name, Roman has played a crucial role in the development of the ProDiver collection ahead of its launch in 2009.It was his insight that led to the creation of the brand’s bezel locking system, known as a Rotation Safety System. Given the level of safety and security protocols involved in his line of work, Roman knew that if he was to be using a conventional dive watch in a modern dive environment, there could be absolutely no room for error, thus a locking mechanism (as seen in other divers like the Omega Ploprof, among others) would be mandatory.Although the roots of the Yacht-Master II relate to activities on the water’s surface rather than deep below, its unique functionality is perfectly suited to this category. After all, the Rolex Yacht-Master II is what is often referred to as yachting timer – a countdown chronograph that can be used to properly measure the start time of a regatta, also known as a sailing race.Arguably the most complex watch in the present Rolex collection, the Yacht-Master II uses an interesting combination of bezel position, crown position, and pusher action in order to set its countdown duration between 1 and 10 minutes, with the chronograph capable of flyback (or fly-forward) functionality to the pre-set time with a single activation of its lower pusher. While many Yacht-Master II wearers are unlikely to ever use this highly specific function for its actual intended purpose. being able to run a countdown like this isn’t shy on practical daily-life applications… grilling timer, anyone?
The Rolex Submariner has been a part of the Rolex catalog for well over 60 years. As expected, the famed dive watch has undergone plenty of design and mechanical enhancements over the past six decades, including the all-important timing bezel. Read on to discover all the different types of bezels of the Rolex Submariner.When Rolex debuted the Submariner in 1953, the stainless steel dive watch included a rotating bezel marked to 60 minutes to allow divers to track immersion times. The steel bezel turned both ways for simple timing adjusting, the edge of the bezel was knurled for easy gripping underwater, and the insert was fashioned from black aluminum.The printed 60-minute scale on the earlier versions included markings for every 5 minutes, alternating between batons and numerals. By the late 1950s, Rolex started to include hash marks for the first 15 minutes on the bezel followed by 5-minute markings.Around 1969, Rolex introduced the first yellow gold Submariner, the Submariner Date ref. 1680/8. Accordingly, the knurled rotating bezel was fashioned from 18k yellow gold. What’s more, the Rolex Submariner ref. 1680/8 now offered the choice of either a black or blue aluminum bezel insert and matching dial.
On top is the sapphire crystal to cover the elegant dial.The bracelet is made of the same material as its case, and on the folding buckle, there are the Rolex logo and other information of the model, just as the same as per original. This replica Rolex Yacht-Master watch is driven by a Asian 2813 automatic movement, supporting its functions well. Even though this watch is designed for professional yacht player firstly, but it became a classic and hot model Rolex. More and more people choose it as a timepiece or decoration on the wrist for sport or business occasion. You know, everything happens in fashion.This replica Rolex Submariner has two edition, a normal edition and a latest V6S edition. Here is the difference between these two: there is a laser Anti-counterfeiting Rolex logo on the front case at 6:00 position, this is exactly as original edition. This logo has to use magnifier or put it at a 45 degree under the light to see it. But, the ordinary edition has the painted crown logo that can be seem directly. There comes very the original Rolex package, very fancy and high-class.Replica Rolex GMT Master II 116710LN Black Ceramic Bezel When the factory told me that this watch is the best replica Rolex GMT-Master II watch so far in the market, I was wondering how it would be. I hold this new arrival in my hand and look into it carefully, then I agree with what I was told. No matter the look or the material, it is exactly the same as the original. I think you would like me to show you more details as below.It seems that Rolex designed the GMT-Master II for specific group, but more and more people who travel a lot or love traveling would prefer to wear this watch. The reason is the elegant look and its useful functions. The 40mm case is made of 314L stainless steel and looks good not only during travelling all over the world but also good for any business occasions. On the black dial, there are dots and stick markers, and except for the hour, minute and second function, there is also date display and GMT. The date indicator is at 3:00, and we can see it adopts Rolex’s traditional water-drop design to enlarge it. On the black bezel we can see there are numbers and markers, this is the most outstanding specification of this GMT-Master II watch, from hands on the dial we can tell the local time, and from the bezel and the 24-hour hand we can tell the time zone when you travel. And this is can be adjusted by the crown, so the traveler can always know the time of the departure and arrival places at the same time. The bezel is made of ceramic material, matching the sapphire cover perfectly. The strap is very Rolex style type, matching a folding clasp.The reason they said this is the best edition of replica Rolex GMT-Master II is that it is driven by a 1:1 super clone 3186 automatic movement, which can support it to work as well as the original. And, this watch looks younger than other gold and stainless steel models, looking good on the young as well.Specification: Movement: Clone 3186 Automatic Case: 40mm*13mm, 316L stainless steel Bezel: Real Black Ceramic Crystal: Sapphire, Anti-scratchDial: Black Bracelet: Solid 316L Stainless Steel Water Resistant: 100m .Replica Rolex Day Date II Two Tone 18K Gold Watch ReviewI am going to show you a replica Rolex Day Date II watch that is a very classic model from this classic watch brand. As one of the brand’s iconic models, Day Date II is always made of steel and gold, which becomes a perfect match as a case of this brand. The replica edition of this Rolex watch I want to present to is the best one I have met, as it is made of real 18K gold instead of gold-plating in most of the replica versions.Looking on the elegant white dial, we can see there are three golden needles and Roman numeral markers. I always like Roman numeral markers are much more than other styles, what do you think? At 12 o’clock position is the week window, and below the window there is Rolex’s logo which is attractive as always.
