The Rolex Sea-Dweller is the big brother to the Submariner. With a helium escape valve, the case sits larger on the wrist but still wears great. Pretty unique, the Sea-Dweller has a date window but no cyclops.
This example comes with the Rolex Service Certificate from 2017 and a super sharp and clean case.
