Timex Deepwater Reef Titanium Dive Watch

Timex tested its Deepwater collection with free diver Francesco Sena, who descended 138 feet in the third-deepest pool in the world, Italy's Y-40. The Reef 200 Titanium has a 41mm case and bracelet in Grade 2 titanium, chosen for its strength relative to its weight, and is water resistant to 656 feet. A sapphire crystal covers a date window with a built-in magnifier, and the unidirectional bezel, hands and markers are filled with Super-LumiNova, which glows in the dark. A Japanese-made Miyota automatic movement winds with wrist motion, and the brushed bracelet adjusts to wrists from 5.9 to 8.1 inches. The watch is also sold on a rubber strap.
