Phenomenal watch that works well outdoors. I ride/ race dirt bikes and constantly hit trees, rocks, the ground,and even other riders during Hare Scrambles. I do use glass screen protectors but it is a computer for the arm. Mud,rain, dirt, daily wear running equipment for my job and this watch keeps up with everything I need. I graduated from the T Rex Pro to the Ultra because of the dirt bike function and the ruggedness I knew it was capable of. Cleans up well for street wear too! Basically this is the ultimate 24 hour wear watch other than when charging it but that is maybe every other day.
