Differences 

Though the Rolex Submariner and the replica Rolex Sea Dweller have several similarities when it comes to appearance, the Submariner has one thing that the Sea Dweller does not: a Cyclops lens to magnify the date display. The original Rolex Submariners had no date function, and among watch collectors and Rolex enthusiasts, there is some sort of purity to them. The Rolex Submariners got the date function in the 1970s. Most Rolex Submariners today have the date, so the “No Date” version is of course the more unusual model. On the other hand, the Sea Dweller models are appealing for their inherent toughness and amazing engineering. For those looking for a cleaner and less conspicuous Rolex, the Sea Dweller’s lack of a date magnification, or “cyclops”, is also an attractive aspect; The Rolex Sea Dweller is more suited for deep sea divers and treasure hunters. The Deepsea Sea-Dweller is waterproof to 3900 meters; The Sea Dweller is bigger because of the sapphire crystal, which is 4mm thicker than the sapphire crystal on the Submariner.
