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.
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.
The GMT Master II ref. 16710 is one of the most iconic and influential examples of the brand’s multi-time zone pilot’s watch. It brought an upgraded case and movement to the line, making it a huge success and leading to its impressive production run of almost twenty years. The ref. 16710 was then replaced by the ref. 116710 in the late 2000s as a completely new generation of Rolex GMT-Master tool watches began to make an appearance with a brand new case and bracelet design, improved materials, and a new movement.Rolex developed the GMT-Master in the early 1950s at the request of Pan Am Airlines. Its release came during the dawn of international flight. The famous air carrier required a dual-time wristwatch to issue their pilots, and the GMT-Master was born. The GMT-Master II was released a number of years later in 1983 with the ref. 16760, and brought with it independent hour hands that allow the wearer to read two time zones on the dial and a third on the bezel.The first GMT-Master II ref. 16760 featured a bulkier case and is often referred to by avid collectors as the “Fat Lady” or “Sophia Loren.” In 1989, Rolex would release a refined variation of the Fat Lady GMT in the form of the sleeker reference Rolex 16710 with a thinner case and movement. The ref. 16710 was well-received among collectors for its upgraded case and movement, and it would go on to become one of the most successful GMT-Master II models, remaining in production for nearly twenty years.A completely redesigned version of the stainless steel Rolex GMT-Master II was introduced in 2007, which meant the discontinuation of the long-running ref. 16710. The Rolex 116710 is similar in design as its 5-digit predecessor with an all-steel finish, a perpetual movement with independent hour hands, and a bidirectional bezel; however, that’s where its similarities end. The ref. 116710 is almost an entirely new watch and boasts a redesigned bezel, case, bracelet, and dial, as well as the newer Caliber 3186 perpetual movement.
On brown dial, each detail is very close to genuine, cream yellow Arabic hour markers are three-dimensional and plump. Blue steel hour and minute hands are wide, they are applied with luminous material, so are hour markers. The dial has a perfect lume effect at night. The Lume light is green and lasts for a long time. At 3 o’clock, date is displayed through a small square window, date font is white and has the correct thickness. More important, the date font is centered in the window, not too right or too left.Genuine IW327006 titanium watch is equipped with IW35111 in-house movement, which is actually developed from Swiss ETA 2892. The replica uses a Sea-Gull 2892, which has the same construction as ETA 2892, maybe the decoration on rotor and movement plate is different, but the watch has a solid case back, so I do not care the decoration, as long as it is stable. Absolutely if you do care about the subtle details, you can install one genuine ETA 2892 inside the replica by yourself, it is easy. The improved Sea-Gull 2892 movement of the replica has the same winding feel, its date adjusting direction is also correct.
First, its size is 40.9mm×12.3mm, which can satisfy your requirement in sense of beauty. It is a little big with such diameter, and it is thinner than other normal wrist watch. Using such different size proportion really can give us special feeling in vision. And such unique style is almost revealed in every design details perfectly. Its case was made of solid 316L stainless steel, which is so delicate and bling in appearance. Combining with the scratch-proof sapphire crystal, it is so perfect collocation that has reflected its skillful craftsmanship fully. And also reflects the extraordinary temperament of wearer at the same time. Its dial uses black color, which can highlight its elegance and nobleness. What’s more, It’s markers are in golden, really a good matching with its black dial. It can be more lived with such decoration. Gold and black as main color in the whole, it reveals the style of gentleman. As we all known, In China, gold color means noble, which is only used for king in ancient age, and most of us still has this feeling now.
