I love this watch it looks really cool. It works great and no battery. I replaced a my boliva submariner for this watch and so glad i did. I beat the tar out of my watches weather it diving or at work they take a beating and this one i have had for 3 months now and is working great! The blue on this watch is so bright and so cool. I would definatly buy another invicta watch but hopefully i won't have too!
