Red-eye flights, dim hotel rooms, unfamiliar time zones and the odd dip in a resort pool: the Marathon TSAR WW194007SS-0112 is a very good travel companion. This 41mm Tritium Search and Rescue diver combines Swiss quartz accuracy, a black dial and a stainless steel bracelet in a package that asks almost nothing of you on the road.

Travel is where tritium earns its keep. A luminous paint dial fades after a few hours in a dark cabin, but the tritium gas tubes on this watch's markers and hands keep glowing all night, so checking the time at 3 a.m. never means fumbling for a phone. The date at 4:30 helps when days start running together. A sapphire crystal stands up to airport security trays and carry-on zippers, and the screw-down crown means you never have to think twice before swimming or stepping into a shower.

The quartz movement, a Swiss ETA F06.115 HeavyDrive, also keeps you from returning home to a stopped watch. The bracelet is the right call for a trip: no strap to soak through in humidity, and it looks appropriate at dinner after a day on the water.
