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.
Case is 42mm in diameter, made of 316L stainless steel and has a fine brushing. Bezel and lugs are well connected, whole case profile is 1:1 replicate from original.Arc-shaped sapphire crystal has ar coating, the sapphire has passed hardness test by special instrument, and it is highly scratch resistant. Under sapphire crystal, it is black dial that has several layers to give wearer a great three-dimensional visual effect. The replica has white, black and blue options on dial. Rome hour markers are made of 18K platinum, each is well built. Date is shown through the small window at 6.Bracelet is in high quality, I do not know what type of bracelet it is, but indeed attracts my eyes, I think it looks more beautiful than Rolex Oyster bracelet. Buckle is deployant and has the same construction as genuine.If you are looking for a replica Omega that looks perfect from inner to outside, this is the one. You will never regret, and the watch will match any type of dresses especially good for meeting in business occasions.
The dial is in dark grey and got its design idea from the dashboard on Spitfire. So is the replica. Case diameter is 43mm, so the dial looks big. With a sloping inner bezel and sunk subdials, the whole dial looks very three-dimensional. 60-second small dial positioned at 6:00 is for small seconds display, top subdial at 12:00 is for minute chronograph. Small second hand is in striking red. There is a fan-shaped window at 3:00 with a triangle mark that is pointing at current date. White lume is applied on hour markers at 12, 3, 6 and 9, so are on hands.Like case, the bracelet is also made of solid 316L stainless steel, it contains five sections of links. The clasp is so special because it has unique fish-scale patterns, we call them Geneva Stripes that were only found on movement plates before. Deployant buckle has a polished square metal part that has engraving “IWC”. Inside the case, it is a Valjoux 7750 movement, well it is a cloned one, not real Swiss ETA 7750. But the factory used a Shanghai chronograph movement to clone this 7750 movement, if you know something about Shanghai Watch Factory, you will learn that Shanghai 7750 is the most stable chronograph movement used in replica watches. At last, let’s check the watch specification of this replica.
