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.
IW389001 is in whole black, including the dial, it is the model I prefer. While IW389002 has a green dial. There is one little difference between the two watches on the dial, that is IW389002 has a red circle on the center of the dial to display 12 hours. Two subdials are positioned at 12 and 6 o’clock. The subdial with a small red hand is small seconds subdial, while the subdials at 12 o’clock have two small dials in sunken design, the outer one is 60-minute chronograph counter, while the inner one is 12-hour chronograph counter. All hour markers are in white, the markers at 3, 6, 9 and 12 o’clock are applied with luminous material, they will emit a strong green light at night.Compared with the green dial of IW389002, I like the black one of IW389001 more. It has a match of white details in blackground, which greatly increases the dial readability. Black looks cooler too.
I believe that you have a overall look at the new replica IWC gentleman now, welcome to leave your comments or questions, would like to communicate with you.AquaTimer is a great collection of IWC, it belongs to the diving watch series of IWC, actually, AquaTimer had become a famous diving watch a long time ago, it was the first batch of professional diver’s watches released in watch industry, and has made a great contribution in the development of diver’s watches. In recent years, it seemed like IWC has ignored the research and development of AquaTimer series, because there were no attractive and striking models added to their AquaTimer collection in SIHH each year. About this replica IWC AquaTimer 2000 I am going to introduce today, its genuine watch was the latest model in 2016, but still not a big surprise to us. In my opinion, IWC added too many modern elements into the design of this AquaTimer, although the watch is full of modern and high-tech sense, it has lost its original taste – that’s the favor we could find in all old AquaTimer models. I think IWC has put too much focus on their Pilot series.
