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.
While their sister-company, Tudor has garnered a strong following with their vintage-inspired heritage watches, Rolex is notorious for only moving forward with their designs, and never re-creating (or re-releasing) vintage Rolex inspired watches from the past. However, despite not manufacturing any outright heritage watches, Rolex does implement a few subtle, vintage-inspired design traits into the otherwise very modern watches that they manufacture today.Most obvious among the various vintage design elements is the red line of text on the dial of the new Rolex Sea-Dweller reference 126600. An obvious throwback to Rolex’s early Submariner and Sea-Dweller watches which had their respective names printed in red letters on the surfaces of their matte black dials, the red line of text on the dial of the new Sea-Dweller 126600 is an unmistakably vintage-inspired design element, which Rolex has recycled and reintroduced on an otherwise very modern and technologically-advanced, luxury dive watch.
While bidirectional rotating bezels may be quicker for wearers to turn to the appropriate spot, as a dive bezel it’s not the best option. If the bezel gets accidentally knocked, this could cause divers to miscalculate how long they have been underwater. Therefore, a unidirectional bezel is more prudent because accidental knocks to the bezel can only result in overestimating immersion time – it’s far preferable to start ascending to the surface earlier or spend longer than necessary at a decompression stop.Rolex began equipping the Submariner with unidirectional bezels starting with the Submariner Date ref. 16800, which was introduced around 1979. The no-date Submariner model received a unidirectional bezel with the introduction of the Submariner ref. 14060 in 1990.Like the previous generation, the new unidirectional bezels included aluminum bezel inserts. In 1983, Rolex introduced the first two-tone Submariner model in the form of the Submariner Date ref. 16803, which sported a yellow gold knurled bezel with a black or blue aluminum insert. To celebrate the 40th anniversary of the Submariner in 2003, Rolex introduced the stainless steel Submariner Date ref. 16610LV with a green bezel insert.In 2008, Rolex introduced the first Submariner models equipped with unidirectional bezels featuring Cerachrom inserts. Cerachrom is Rolex’s proprietary ceramic alloy that is not only resistant to scratching but also to fading. The 60-minute graduations are cut into the bezel and then the ceramic bezel insert is fully coated with either yellow gold (for yellow gold and two-tone models) or platinum (for white gold or steel models). The gold/platinum is then polished away from the ceramic surface until only the recessed numerals and markings are left with the metal filling.By 2012, Rolex had rolled out the Cerachrom bezels across all Submariner models and color options include black, blue, and green. A quick way to know the color of the bezel is to look at the letters in the reference number: LB (blue bezel), LN (black bezel), and LV (green bezel).
IWC watch is always famous for its thin, big dial and elegant design, every gentleman likes to own at least one IWC watch. Z factory has been tried hard to released different editions of replica IWC Portuguese Chronograph IW371445. And they are getting better and better on everything, this time, Z factory engineers have been spending more than 18 month to do this V6 edition and I think this is the best edition that I have ever seen out there from the market. Is there any difference between the original and V6 edition? Comparing the two, which are almost the same only some slight differences. Let’s have a careful look at it.
This replica with a big white dial,42.3mm, it is easy to see time having this design, and collocates with blue hand, it can up its charming glamour and be more attractive at the same time. There are some details also reveal the symbolic design of Portuguese collection fully. For example, its dedicated minute ring is liked track, the relief Arabic numerals, the dedicated leaf hand. What’s more, combined with white dial and blue hand, it is really more vivid as a whole with this detail. Almost all these details are designed for gentlemen specially.
After in stock again, let’s check the most important place that has been improved on this replica watch. It is the 8500 movement. The replica uses a completely new movement, which took V6 factory one year to research and produce, it is not based on Miyota or Asia 2824, it is just a brand-new movement that was independent designed by V6 factory, according to genuine Omega 8500 Caliber. Now this re-made movement works completely same as genuine, such as real hack feature and independent adjustable hour hand to adjust hours and date. The movement not only looks the same as genuine in appearance, it also functions like real.About other details, they are as accurate as older edition. Dial is sandwiched and the bottom plate is applied genuine Swiss Superlumed material, top plate has skeletonized hour markers, and there are 3-6-9 Arabic numeral markers. Silver hour and minute hands are cut very well and full of angular sense. The Omega Logo and “OMEGA” word are not printed, they are stainless steel made in silver tone, raised from black dial, just like the 3-6-9 hour markers.
The first ceramic bezel Submariner appeared in 2009 with the introduction of the steel and gold Rolex reference 116613. A stunning blend of classic and modern dive watch design, the ref. 116613 has since become a highly sought-after dive watch, both at retail and on the pre-owned Rolex market. Other metal variations of the ceramic (aka “Cerachrom”) bezel Submariner would later follow. However, none is as intriguing as the Rolex Submariner two-tone example.The Rolex Submariner was introduced to the market in the early 1950s and was the first timepiece in the brand’s catalog to offer water resistance up to 100 meters. This depth rating would eventually be increased to up to 300 meters, where it remains for the modern versions of the Submariner that are sold today. Other notable upgrades made to the line over the past six decades include improved materials (904L Oystersteel), longer-lasting lume (Chromalight), higher-beat Caliebr 3135 perpetual movements, tougher scratch-resistant sapphire crystals, and unidirectional rotating timing bezels.The Submariner was first offered in stainless steel, then in yellow gold. The first two-tone Submariner wasn’t released until 1984, with the reference 16803. This take on Rolex’s famous professional diver introduced the line to a brand new level of collectors who sought a gold Rolex but didn’t have the budget for an all-gold timepiece. Fast forward to 2009 with the release of this article’s featured ref. 116613, a completely redesigned dive watch with an upgraded bracelet and case, a redesigned bezel fitted with a ceramic insert, and a larger display on the dial.The Rolex Submariner is a dive watch legend. From its many appearances in the James Bond franchise to gracing the wrists of numerous A-list celebrities, the Submariner has become one of the most recognizable and coveted luxury watches in the world. The line is varied and offers options in either an all Oystersteel (904L stainless steel), Rolesor (two-tone steel and gold), or solid 18k gold. Today, we will compare two of the most iconic two-tone Rolex Submariner references – the Rolex 16613 and Rolex 116613.
The chemical composition of synthetic green sapphire includes copper and aluminum oxide, with the copper being the element that is ultimately responsible for its signature green hue. The process of synthetic sapphire production is an expensive and exacting one; however, the additional obstacles that accompany the addition of copper – and the precision required to achieve the right amount of green tint without compromising the strength or clarity of the crystal are likely responsible for its exclusive use on the Rolex Milgauss line of watches.When synthetic sapphire is manufactured, the material has to “grow” over the course of a period of several weeks. Particles attract to one another, forming layers that fuse together to create a dense and ultra-hard substance. The end result of production is a “boule” – a solid piece of synthetic sapphire shaped like a chunky cylinder, which is then cut and shaped to its necessary dimensions.Due to the high costs of production, most watch crystal manufacturers cut their synthetic sapphire boules in a perpendicular fashion, as to maximize the number of crystals that can be created from a single boule. Although this is entirely unconfirmed, it is rumored that Rolex cuts the boule along a diagonal axis to maximize the clarity and strength of the finished crystal. In addition to complicating the cutting and shaping process itself, cutting the boule along a diagonal axis significantly increases the amount of waste, which further adds cost to an already expensive manufacturing process.Despite not making an appearance until just over ten years ago, the green sapphire crystal has quickly become one of the defining characteristics of the Milgauss line. Its pale green tint possesses no functional advantages over a traditional, clear/uncolored synthetic sapphire crystal; however, the green crystal that is exclusively fitted to the Rolex Milgauss 116400GV is one of the primary reasons that individuals seek out this particular reference. The green crystal is something entirely unique to the Milgauss collection and is not something that is found on any other Rolex watch, past or present.
