As previously mentioned, the case also received a ceramic “Cerachrom” insert, which is virtually scratch-proof and will not fade and lose its vibrant color like aluminum. The ref. 116613 is also available with Rolex’s patented “Chromalight” lume on the dial, which offers a bright, blue glow for up to 8 continuous hours (as well as larger plots). Similar to the ref. 16613, the newer model Submariner Rolex 116613 is also available with either a blue or black dial and bezel combination. However, the Serti dials on the 116613 only come in blue or black (rather than champagne or silver), and do not feature sapphires set into the markers on the 6, 9, and 12 o’clock locations. Instead, ref. 116613 Serti dials only have 8 diamonds set in them, and feature lume-filled indexes for the 6, 9, and 12 o’clock hour markers.Both the Submariner 16613 and 116613 run on the Rolex Caliber 3135 perpetual movement with a 48-hour power reserve. However, the version of the Cal. 3135 inside the newer ref. 116613 is fitted with an upgraded paramagnetic blue Parachrom hairspring for better resistance to shocks and temperature variations.
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.
