## Description

Men's Casio Pro Trek Triple Sensor (Ver. 3) World Time Watch

Review: Buen reloj - Es mi primer Casio Pro Trek, porque siempre he comprado G Shock, y la verdad está excelente, robusto, eficiente.
Review: Impressed - I’ve wanted this watch for a long time, and I’m so happy I pulled the trigger. I can’t believe how comfortable and lightweight it is. As soon as you pick it up and put it around your wrist you can feel the quality. The features I like the best are the solar feature and the auto light. You can set it so the backlight comes on when you tilt your wrist. And because it’s solar it detects light and only comes on when it’s in low light conditions. Something else to mention is its size. It’s not nearly as big as I thought it would be. It’s very flat compared to most of my G Shocks. So far I’m very happy.
