Titanium is the material of choice for the inner caseback on the Deepsea due to its strong corrosion-resistant properties and its ability to repeatedly flex under stress without developing the same degree of metal fatigue as steel. Since the crystal on the Deepsea will be subjected to the same extreme pressures as the caseback, its scratch-resistant sapphire crystal has been beefed up to be a massive 5.5mm thick, and it is crafted in a domed shape (without a Cyclops magnification lens) to better distribute the pressures being exerted on the face of the watch.Like both the Submariner and the normal Sea-Dweller, the Deepsea is equipped with Rolex’s Triplock winding crown that screws down and uses a system of gaskets to create three sealed zones to protect against moisture intrusion. Additionally, since the Deepsea is a variation of Rolex’s Sea-Dweller collection, its case is equipped with a helium gas escape valve, which allows the watch to safely be used for saturation diving applications.One of the hallmark characteristics of modern dive watches is the degree of the over-engineering present in their designs and the almost-ludicrously excessive performance-statistics that manufacturers are able to achieve. Although the Rolex Deepsea Sea-Dweller is easily the most capable and robust dive watch available in Rolex’s current catalog, only a very slim percentage of its owners will ever require even a small fraction of its incredible underwater functionality. Regardless, the Ringlock system and the case of the Deepsea are the perfect embodiment of form following function, as the watch was specifically designed from the ground-up to be the ultimate deep-sea diving timepiece.
Sticking with undersea operations, the Oris ProDiver collection is an interesting one, given that Oris is one of the few watch companies that remains actively engaged in dealings with commercial divers. More specifically, Roman Frischknecht is a commercial diver that has been an Oris ambassador for some time, and rather than simply being an ambassador in name, Roman has played a crucial role in the development of the ProDiver collection ahead of its launch in 2009.It was his insight that led to the creation of the brand’s bezel locking system, known as a Rotation Safety System. Given the level of safety and security protocols involved in his line of work, Roman knew that if he was to be using a conventional dive watch in a modern dive environment, there could be absolutely no room for error, thus a locking mechanism (as seen in other divers like the Omega Ploprof, among others) would be mandatory.Although the roots of the Yacht-Master II relate to activities on the water’s surface rather than deep below, its unique functionality is perfectly suited to this category. After all, the Rolex Yacht-Master II is what is often referred to as yachting timer – a countdown chronograph that can be used to properly measure the start time of a regatta, also known as a sailing race.Arguably the most complex watch in the present Rolex collection, the Yacht-Master II uses an interesting combination of bezel position, crown position, and pusher action in order to set its countdown duration between 1 and 10 minutes, with the chronograph capable of flyback (or fly-forward) functionality to the pre-set time with a single activation of its lower pusher. While many Yacht-Master II wearers are unlikely to ever use this highly specific function for its actual intended purpose. being able to run a countdown like this isn’t shy on practical daily-life applications… grilling timer, anyone?
There are diving markers on bezel but no pearl set at 12 o’clock. On solid case back, there are engravings of “STEALTH MK IV” on case rim, and featuring an engraved pattern of SBS’ Frog on the centre.The dial is also in black, you will see larger hour markers and fatter hands on this dial, yes, we call it Maxi Dial, which is only used on some Rolex models. So it is very rare. The hour markers have black luminous material applied, so do the hands. All printings on dial are in white color, except the “STEALTH”, which is black in white square background. The date window is set at 3 o’clock, black date font is in white background, it is curious that this Submariner replica watch does not have a date cyclob.The replica watch is equipped with an Asian ETA 2836 movement, which is used on most replica Rolex and gets a better stability than other automatic movement. Some people here always ask me to change a genuine ETA movement for their orders, but I have to say that only certain replica watches made by big factories could be installed with genuine ETA movement. By the way, for all chronograph watches, they can’t be equipped with genuine ETA 7750 movement in replica watch field.Finally, let us see the nato strap, it is a single strap in full black, which is exactly matching the black pvd case of the replica. There are three black steel keepers on the strap. It is very easy for the wearer to remove the band and replace a new one in any color, but you must ensure the new installed band meets the black theme of this replica Stealth Rolex.The replica is the best verion of blue Submariner, it is also the best seller in 2015 and continues to make its legend. There is an anti-counterfeit laser crown at 6, common versions his it printed, the bezel markers are in silver while other versions are in white. The replica has a lot of things improved, the bezel has the same construction as genuine, it has the same clicking sound as genuine, the bezel markers are deeply engraved, crystal is sapphire, the proportion of Crown Logo on dial is modified, the laser crown is in crystal not printed, it consists of laser points. The connector between case and bracelet is improved, black clasp engraving is closer to genuine. There is an independent laser reference number on inner bezel at 6, each watch is unique.
