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.
On brown dial, each detail is very close to genuine, cream yellow Arabic hour markers are three-dimensional and plump. Blue steel hour and minute hands are wide, they are applied with luminous material, so are hour markers. The dial has a perfect lume effect at night. The Lume light is green and lasts for a long time. At 3 o’clock, date is displayed through a small square window, date font is white and has the correct thickness. More important, the date font is centered in the window, not too right or too left.Genuine IW327006 titanium watch is equipped with IW35111 in-house movement, which is actually developed from Swiss ETA 2892. The replica uses a Sea-Gull 2892, which has the same construction as ETA 2892, maybe the decoration on rotor and movement plate is different, but the watch has a solid case back, so I do not care the decoration, as long as it is stable. Absolutely if you do care about the subtle details, you can install one genuine ETA 2892 inside the replica by yourself, it is easy. The improved Sea-Gull 2892 movement of the replica has the same winding feel, its date adjusting direction is also correct.
