Rolex Seadweller Deepsea (44mm)
Launched in 2008, the Rolex Seadweller Deepsea is still the largest watch in the Rolex portfolio. While it has the same case size as the Yacht-Master II, it has a much thicker Oyster case, in order to accomodate the Ringlock System – a central ring that supports its extra-thick sapphire crystal and titanium caseback. All these features give the Deepsea an amazing water resistance of 3,900 meters or 12,800 feet.
Rolex Seadweller (43mm)
In 2017, Rolex launched an updated version of its saturation dive watch, the Sea-Dweller. From its 40mm case, the Sea-Dweller now measures 43mm. This move distinguishes it from Rolex’s classic dive watch, the Submariner, and also provides another option for those who want larger dive watches.
