Saltwater, chlorine and sweat are no match for this pairing. The Marathon Arctic SSNAV-D, reference WW194013SS-0530, puts the white-dial 41mm Steel Navigator with Date on a black 3-piece FKM rubber strap kit, ready for the beach, the boat or the gym.

FKM rubber resists oils, UV and chemicals far better than basic silicone, and Marathon's 3-piece kit is made in La Chaux-de-Fonds, Switzerland, where the watches themselves are assembled. It rinses clean in seconds and dries fast, a natural match for the 10 ATM water resistance secured by the screw-down crown on the 316L steel case. The 11mm profile keeps the watch comfortable through workouts and long days in the sun.

Bright conditions are exactly what the Arctic white dial was built for, and the date at 4:30 is easy to read against it. When the sun goes down, tritium gas tubes illuminate the hands, markers and bezel pip without any charging. Accuracy comes from the ETA F06.412 PreciDrive, a thermocompensated Swiss quartz movement good to about ten seconds annually. And the 90-click bi-directional 12-hour bezel, inherited from the Navigator Marathon designed with Kelly Air Force Base in 1986, lets you follow home time from anywhere.
