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.

In recent days, AR factory published a lot of Rolex Daytona replica watches that are made of genuine 904L stainless steel, these Daytona replica watches are best of the best in our market, however, these Daytonas have one fatal flaw, that is the non-working minute and hour chronograph. So, although ARF Daytona replica watches are made of the best material, they are still not perfect for watch fans who require full functional chronograph. Today, the Daytona replica watch that is going to be discussed in this article is an old model published last year, by J12 factory. Although the watch is made with 316L stainless steel and equipped with an Asian Valjoux 7750 movement, it works accurate, you know, high stability is very important for a chronograph watch. Nowadays, replica watches from big factories like Noob, J12, BP and ZF could be made 99% the same as genuines in outlook, only the movement is the biggest flaw, so to make the fake movement look closer to genuine caliber, these factories are spending a lot of time and effort in modifying the basic movement to make it look real, everyone knows too much modification on movement will affect its stability, so, in my opinion, these new Super Copy 3135 used on Submariner and clone 4130 on latest ARF Daytona are not as good as you think. However, this yellow gold Daytona uses the old Asian Valjoux 7750 movement, whose accuracy and stability have been tested for years by a lot of chronograph replica watches, so, this Daytona I am about to post is very rare and really good, you will never regret after purchase.

Made by J12 factory, the case polishing work looks much superior to Daytonas of other factories. Case is 40mm in diameter and 15mm thick, case corners and edge are smoothly polished, so you will get a comfortable wearing feeling from this replica watch. Bezel is in yellow gold tone and fixed, three buttons on the right are also in yellow gold and have the same construction as genuine Rolex Daytona. When not in use, the two chronograph buttons could be locked tightly by screws to make sure the watch is water resistant. If you want to start the chronograph, just loose the screw on button at 2:00 and then push it.White dial has three working subdials, the small dial at 6 o’clock is for small seconds display, the subdial at 3 o’clock is 30-minute chronograph counter and subdial at 9 o’clock is 12-hour chronograph counter. Fortunately, all could work like genuine Rolex Daytona. Secs@6 Valjoux 7750 chronograph movement is very reliable.The bracelet is made of 316L stainless steel and has a thick yellow gold coating on the central links, the yellow gold tone never fade. The last reason why you choose this replica Daytona other than the ones from AR factory is it is sold at a much cheaper price.After releasing Submariner 116610 and 116610LV, Noob just published another important model in this week, it is 116710 BLNR. This Rolex Submariner was selling well and I have given its review on my another blog. 116710 BLNR is a popular GMT Master II watch of Rolex, it is easily identified because of the blue black bezel, some watch fans call it Batman bezel. 116710 BlNR I introduced before was a V7 published by Noob factory, the one I am going to discuss today is the latest V8 by Noob, it is currently the best version that uses top quality watch material and Swiss 3186 automatic movement.
