Deep Sea depth rating = 4482m/14710ft ??

The depth rating on the new Sea Dweller Deep Sea is 3900m/12800ft, however Rolex states that this watch can withstand a colossal 2.98 metric tonnes of water pressure.

2.98 metric tonnes = 6570 PSI, which is the equivalent of 4482m/14710ft


Could the listed depth rating of the Sea Dweller Deep Sea have anything to do with this:

"The average depth of the Atlantic Ocean is 3,900 meters (12,800 ft). The ocean bed is made up of hills, mountains, tablelands and valleys just as on dry land."
