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.
Maybe they have already felt strong competitiveness from AR factory, if still can not bring us some big surprises, they will be completely defeated.Back to the V10 Submariner 116610LN and 116610LV. The biggest change is made on the bezel, which Noob factory claims that is could be interchanged with the bezel of genuine Submariner. The engraved depth of the bezel markers are the same as that of genuine Submariner, besides, the Platinum tone of the bezel markers will not fade as time goes by.About the movement, Noob offers two options, one is an Asia ETA 2836, the other is a Super Clone 3135. The latter one has the same time and date adjustment as genuine Rolex 3135 Calibre. Both have a high quality.Please read the following specification to know both watches better, and check a lot of photos below. Movement: Super Asia 3135/Asia ETA 2836 Automatic Case: 40mm*13mm, Solid 904L Stainless Steel Bezel: Uni-directional Rotating Black Ceramic, Anti-clockwise Crystal: Sapphire with Etched Crown Logo at 6 o’clock Dial: Black with Superlume on Hour Markers and Hands Bracelet: Solid 904L Stainless Steel with Deployant Clasp Water Resistant: 30m
