At the heart of the Deepsea’s case is Rolex’s patented Ringlock system, which uses a super hard, nitrogen-alloyed steel central ring to internally support both the extra-thick sapphire crystal and the Grade 5 titanium caseback. While the Ringlock system is largely responsible for the overall increase in the case size of the Deepsea, it actually enables the watch to be smaller than it otherwise would be, had it were to follow a more traditional case design while still retaining its same colossal depth rating.The primary purpose of the Ringlock system is to reduce the amount of stress placed on the case of the watch. As pressure on the watch increases at greater depths, the majority of it gets exerted on the front and back surfaces of the watch. Since the nitrogen-alloyed stainless steel compression ring internally supports both the crystal and the caseback of the Deepsea, the amount of force exerted on the actual case itself remains relatively minimal. Additionally, as the crystal and caseback get squeezed together, with the majority of the force being supported by the internal compression ring, the front and back gaskets of the watch get pressed together, ensuring an extra tight seal.The caseback on the Rolex Deepsea consists of two components: an inner caseback made from Grade 5 titanium, and an outer, screw-down caseback ring that is constructed from Oystersteel (904L stainless steel). With a traditional, single-piece, caseback design, the entirety of the pressure placed on caseback gets exerted on the case of the watch itself, particularly near the threads. By separating the caseback into two components, Rolex is able to redistribute much of the force being exerted on the rear surface of the watch. The outer, screw-down ring performs the sole duty of keeping the inner, titanium caseback tight on the watch, while the nitrogen-alloyed steel compression ring ultimately supports all the pressure being exerted on the titanium case-back itself.
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.
Other Submariners do not have engravings on case back. From the case back, you can see the pins that connect the case and bracelet, they are crafted to be better so that could firmly connect case head, every piece of the bracelet link is made of solid 316L stainless steel, holding the replica is like wearing a genuine Rolex.In a word, the replica inherits all advantages of Noob 116610 LN Submariner but has its own unique features.This is another great vintage project in the replica watch market, which comes with a replica Rolex Submariner. The replica is manufactured by the same factory as Daytona 6214. I have introduced several pieces of replica watches including Panerai and Rolex in my blog, many of them attracted a lot of readers here and they asked me the price, I have to tell them these vintage watches are all sold at reasonable prices. Ref. 5510 should have be the oldest Submariner model Rolex made, it already had the features of modern Rolex Submariner like Mercedes-Benz hands and rotating bezel, however Submariner 5510 also has the iconic features of its own. Here I will introduce the replica to let you know more about those vintage Rolex watches made in old times.The most outstanding place that also makes the watch full of vintage style lies in its dial, which is black. The hour markers of 3-6-9 and bar-shaped also make it different from other Submariner watches. These hour markers are all applied with yellowish luminescence, so are the hands. The dial printings are also in yellow color except the words “200m = 660ft”. Next to the hour markers, there is a circle of minutes scales in track style, which is also different from modern Submariner watch. We actually call such dial “Explorer Style”. The bezel insert is black and features white printings, there is a pearl at 12 o’clock in red triangle background.
Although the Rolex Submariner began its life in 1953 as a sturdy no-frills stainless steel dive watch, today, this famed diver is considered to be one of the world’s greatest luxury watches – while still very capable of plunging into the deep to accompany aquanauts. The Sub’s graduation from utilitarian to upscale no doubt began when Rolex introduced the very first Submariner in solid yellow gold. Nothing says fancy like armor made of shiny precious metal. Let’s find out which reference was the first Rolex Submariner gold watch and lay out the details. When your life depends on a limited tank of oxygen strapped to your back, you are naturally more concerned about the passing minutes rather than what day it is. Which explains why early dive models from the 1950s (Fifty Fathoms, Submariner, Seamaster 300, Breitling Superocean, etc.) didn’t worry about putting a date window on the already limited real estate of the dial. The First Yellow Gold Rolex Submariner Not only did Rolex make the Submariner ref. 1680 in stainless steel, but the company also manufactured a solid yellow gold Submariner 1680. It’s important to note that the first yellow Sub is sometimes simply called the yellow gold Submariner 1680 or the Submariner 1680/8; however, it is not the Submariner 16808 – that’s an entirely different generation. Back to the yellow gold Submariner Date 1680. Rolex’s first gold diver made its debut in 1969, flaunting an 18k yellow gold 40mm Oyster case fitted with a matching 18k yellow gold Oyster bracelet. Early examples of the Submariner ref. 1680/8 featured a rotating bezel with a black aluminum insert and a matching black dial.
