Due to high demand, we added stealth to the Torpedo Pro range with the new Ion-Pro. The all black steel case will keep you on target, whether you are on the ground or exploring the deep. In order to combat the darkness of the deep, we added luminosity to the hands, dial markers and the bezel marker. To back it all up, the Ion-Pro comes standard with Sapphire Crystal. This is a watch you can be sure to have your back.
