The Rolex Sea-Dweller 16600 is about as classic as brand watches get in the sport watch category. It’s the kind of piece you buy once and wear forever—built for saturation diving but just as comfortable on dry land. With a 40mm case, no-cyclops crystal, and a real-deal tool watch feel, this one hits all the right notes. It’s got enough wear to give it personality without compromising condition. For anyone looking to add a versatile Rolex sport/dress watch to the collection, this is a no-brainer—especially with box and papers from 2001.
