The myth of the Sea-Dweller
For many watch lovers and Rolex collectors, the Sea-Dweller is something exceptional. While the Submariner is already one of the biggest watch icons, the Sea-Dweller, which belongs to the Submariner series, is something like the Toolwatch among the Toolwatches: it has a helium outlet valve that is attractive for professional divers and has higher water resistance.
In the case of the Rolex 126600, the water resistance is a lush 1,220 meters - around four times that of the Submariner. While the previous references only had a higher housing due to the better water tightness, Rolex has given the reference 126600 a larger housing at 43 millimetres.
