Description: The 16660 or otherwise known as the “666” Sea-Dweller is a tank of a watch. Its appearance may appear like a 16800 at first glance, however the dimensions of this watch wear very differently. For starters the entire case is a bit thicker than its Submariner counterpart. In order to balance this extra heft the Dial shrinks ever so slightly but gives it a completely different experience. The Depth rating on this Neo-vintage Sea-Dweller is now 4000ft with the thicker case and larger helium escape valve from its predecessor.  This piece comes with box and papers along with original accessories specific for Sea-Dwellers of this time. The case looks amazingly thick with sharp bevels throughout the lugs
