Rolex Comparison between Sea-Dweller and Deepsea

As we all know that the fake rolex Submariner is their most popular and best selling dive watch; Rolex manufactures two other watches that were typically made to out-perform the Submariner at conquering the depths of the ocean. Originally conceived during the 1960s, Rolex’s Sea-Dweller line of ultra-resistant dive replica watches aims to pick up where the Submariner left off, enabling its users to dive deeper and stay at depth longer.
The most recent iteration of the Rolex Sea-Dweller collection, just this model and the older, even more extreme brother, the rolex Deepsea are among the largest and most water resistant watches that Rolex has ever put forward. Although they were both designed with a similar intended purpose, the Sea-Dweller and the Deepsea are totally different watches.  16718-030515-16
Although the Sea-Dweller has traditionally been a 40 mm watch, the replica watch has seen an increase in size to a 43 mm case diameter. What’s more, while previous iterations of the Sea-Dweller have traditionally had flat crystals, the model, however, adds Rolex’s iconic Cyclops magnification lens to the surface of the crystal. With the exception of the “Sea-Dweller” name printed in red on the surface of the dial, this model most closely resembles a larger version of the contemporary, stainless steel Rolex Submariner.
Despite having a particular and highly specialized case, the fake Rolex watch is powered by Rolex’s proven and reliable Caliber 3135 movement. Rolex has been fitting the Caliber 3135 inside their date-displaying watches since its initial introduction in 1988; however the Caliber 3135 is a rock-solid and notoriously dependable, self-winding movement that has earned a legendary name for being able to bear the test of time.
The outstanding inner bezel on the Deepsea is actually a structural component of the watch’s case design. The extra thick, domed sapphire crystal sits on the inner bezel ring, which is made from extra hard and nitrogen-alloyed steel. As the massive pressures found deep below the ocean’s surface press down on the crystal of the Deepsea, the crystal is supported by the inner bezel ring, allowing the watch to withstand water pressure equivalent to a weight of more than 3 tons on the crystal.
Besides, the case-back on the reference 116660 Deepsea is a design specifically engineered to allow the watch to withstand incredibly high pressures that would otherwise deform traditional case-backs. While the case-back on the Sea-Dweller is the usual, solid, stainless steel variety, the case-back on the Deepsea is a multi-part system, in which a slightly flexible titanium cover sits against the other side of the inner bezel support ring, while a stainless steel, donut-shaped piece screws on top of the titanium cover to hold it all together. As depth increases, the water pressure forces the crystal and the titanium rear cover into the gaskets of the watch, pressing them against its extra hard, nitrogen-alloyed steel support ring. This design allows the seal of the Deepsea to improve as pressure increases, enabling even bigger possible depths. 
What are your thoughts on these two models?
Both the replica rolex Sea-Dweller and the Deepsea Rolex are among the most robust and water resistant watches that Rolex has ever manufactured. Generally speaking, the Submariner offers far more moisture protection than they are ever likely to need; however for those that truly require the utmost water resistance, there are no better choices than the Sea-Dweller and the Deepsea.
