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.
As the series of Planet Ocean, how can ignore its powerful movement to handle with its operation overall. This replica equipped with Plated Swiss Eta 2824-2 Automatic Movement, and with the function of shock resistance. It was sure that it can be precise and stable in travel time.Such outstanding replica Omega, no matter you stay on land or explore deep sea, it may bring you more surprise. You was just like the movie of 007, accompany with this wrist watch to get through any difficulties and enjoy you life.
The case is 40mm in diameter and made of 316L stainless steel, round bezel is very thin, so we can see a very big dial under the sapphire crystal. Whole case is brushed, including four lugs. The face of bezel is also brushed while polished on edge. Like genuine, you can operate the two pushers to start or stop chronograph. Case back is locked by four screws, there are vertical brushing on the center. When open the case back, the inside has beautiful geneva stripes and correct engravings like genuine watch.Dial is blue. There are two small dials at 6 and 12. The subdial at 6 o’clock is displaying small seconds, while the subdial at 12 o’clock is for 30-minute chronograph. The two small dials are sunken on the main blue dial, together with the beveled inner bezel, the whole dial shows a 3D visual effect. Besides, silver Arabic numeral hour markers are also three-dimensional.
The Oyster case was an innovation of its time when it was developed by Rolex in 1926. It ushered in a brand new era of durable, everyday watches that could be worn during almost any activity without damaging the internal movement. The Submariner takes the design of the Oyster case one step further and increased its waterproofness up to 300 meters/1,000 feet.The ref. 16613 features a standard 40mm case in highly corrosion-resistant 904L stainless steel. An 18 karat yellow gold screw-down crown and unidirectional bezel accompany the case, giving it a desirable two-tone design. The dial and bezel set are most commonly available in either black or blue, with some examples of the gem-set “Serti” dial (either champagne or silver in color and set with diamonds and blue sapphires) also available on the secondary market. Depending on the year produced, the ref. 16613 also features either a holes or no holes case and either Tritium or LumiNova used for the luminescence on the dial and hands.Regardless of the year of production, all two-tone Rolex 16613 Submariner watches are powered by Rolex’s trusty Caliber 3135 automatic movement. The 31-jewel movement beats at a rate of 28,800bph and includes a date complication, a 48-hour power reserve, automatic winding technology, and a sophisticated Breguet overcoil balance-spring. The movement has been a fixture in many Rolex wristwatches for more than three decades, and for a good reason. The Cal. 3135 has proven itself to be an accurate and robust movement, which can deliver decades of reliable performance if properly maintained.
Initially only available in White or Yellow Rolesor (Rolex’s name for a combination of steel and gold), they were just successful enough for an all-steel reference with a smooth bezel to follow in 2012.Yet it seemed to be too much of a design departure for either the traditional customer base or else the brand itself, and the Datejust II was discontinued by 2016. The Datejust 41 replaced it as a very much a scaled-up version of the 36mm piece, with the classic dimensions intact.But there was always a relatively small but enthusiastic audience for the DJII, as decidedly masculine a dress watch as you are likely to find. Issued with a range of dial options (although, strangely, only ever produced on the Oyster bracelet) it offers plenty of choices and is the ideal model for a larger wrist.Rolex is very proud of their patented Cerachrom ceramic alloy, and rightly so. Scratchproof, fade-proof, nigh on unbreakable, it is the perfect material for the brand’s bezels and it has been rolled out across most of the tool watch collection. On the Daytona, it is fitted to models forged from platinum, all three flavors of gold, and the only two steel pieces left in the contemporary lineup – those lusted after models which are more difficult to get ahold of than a Wonka factory golden ticket.But Cerachrom is a fairly new invention. Previous iterations of the stainless steel Daytona have always had steel bezels, something no longer obtainable if you are buying brand new. The last reference to have one was the ref. 116520, which ran from 2000 to 2016, and was the first Daytona to house Rolex’s own in-house chronograph movement, the Cal. 4130.
