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.
GM factory grows bigger, now it even has more Rolex in stock than Noob. We need to wait for a long time for Noob factory to release their stocks, but if you place orders from GM factory, then you just need to wait for less time. I have to admit that Noob created the best Rolex replicas in the past, now the glory of this factory no longer exists, its main competitors J12 and GM all do better than them. The only one advantage of Noob factory which they still keep is their super 4130 clone Daytona, now Submariner and GMT-Master are no longer their star products.GM is a great factory, it often publishes new watches and has a large stocks, today, I want to introduce a Yachtmaster II from GM factory, it is the first replica Rolex YachtMaster II watch that is made with 904L stainless steel in our market. In recent years, Rolex has unveiled several YachtMaster models in different sizes, but I still love the YachtMaster with counterdown function, although this replica does not have the counterdown function, it is still a good replica watch.I like this YachtMaster watch due to its blue color usage on the bezel and dial, the blue color is exactly in line with the ocean them which Rolex YachtMaster wants to present. The replica is made of 904L stainless steel on case and bracelet, 44mm case is brushed, with two chronograph pushers set at 2 o’clock and 4 o’clock. The bezel is rotatable and features a blue ceramic insert with deep engravings that has the same tone as platinum markers of genuine Rolex.The dial is white, the circle on the center is for countdown for yachting, while on this replica, the countdown function is fake, so the central hand with a big red triangle does not work. The dial has a good visibility, a small second subdial at 6 o’clock has a blue circle with white markers, central seconds-chronograph hand is in bright red color, which will start to work if you push the button at 2 o’clock. By the way, the hands are updated, they are the new hands which Rolex updated in 2017 basel.Movement is clone 4161, it is the first time for a factory to use a clone 4161 movement on a replica Rolex YachtMaster, you know, even Noob and AR still have not used this movement, so, GM factory created the precedent.
The men’s Rolex Submariner was developed in 1953 and made its official debut during Basel Watch Fair the following year. One of the first dive watches to offer a 100-meter depth rating, the Submariner essentially paved the way for the modern dive watch as we know it today. Over the years, the Submariner has seen many notable upgrades, including the addition of a date display in the 1960s, the switch from acrylic to sapphire crystals in the late 1970s, and the change from radioactive tritium to photoluminescent lume in the 1990s. The Submariner was initially only available in stainless steel; a two-tone variant didn’t become available until 1984 via the ref. 16803.That brings us to the two examples that are featured here in today’s comparison video. The Rolex 16613 made its debut in 1988 and was the final aluminum bezel Submariner. The ref. 116613 was introduced in 2009 and features a completely redesigned feature set that swapped the aluminum bezel out for a tougher Cerachrom ceramic insert and features an all-new case and bracelet design. While both references are similar, they each bring a different aesthetic to the table.The Rolex Submariner 16613 was produced for over twenty years. During that time, it became available in many variations, including either a black or blue dial and bezel set, stunning champagne or silver “Serti” dials adorned with gems, lug holes on the case or no holes, and different luminous material on the dial. Two features that remain consistent among the reference variations are the two-tone steel and gold finish of the case and the aluminum insert on the bezel.With the unveiling of the modern 116613 Submariner in Yellow Rolesor (aka two-tone stainless steel and 18k yellow gold) came a newer-style “Super Case” which, despite offering the same 40mm diameter as the ref. 16613, appears slightly larger. The lugs and crown guard are wider, and the bezel received a new mounting design, giving the case a slightly more robust appearance and refined bezel action.
The case is made of 316L stainless steel and then has 18K rose gold coating plated, the gold coating is thick, which is almost 5 mils. You must concern whether the rose gold coating will fade or not, I must say yes, even gold coating on genuine watches will fade, but on the replica, it will keep its gold tone after two years of wearing, that’s enough for us. The case has a very big diameter, which is 46mm, even though the case is brushed very well, but check its case edge, it does not feel as smooth as replicas made by ZF. The back is see-through crystal, which uses sapphire like the crystal on the front.The dial is in blue color, looks very charming. Amazong all IWC Le Petit Prince models, the one with blue dial is the most popular. Like the case, hour markers and hands all feature rose gold edge. Both subdials have refined circles, the small second hand is runniong on subdial at 9 o’clock. The subdial at 3 is an indicator that is displaying the remaining power reserve. It is marked with 7 DAYS, but the replica has 3-day power reserve. At 12 o’clock, there is a fan-shaped indicator that features three small windows, which displays month, date and week separately. The Annual Calendar function just works the same way as genuine watch. To get a better readability, the replica not only has big hour markers, it also has genuine Swiss lume material applied on markers and hands.
