In the past, Seiko had delivered some of the best design in Dive watch. It is more than just a watch to tell good time, but an instrument to withstand time, task and the environment. I had the 7002 and it is at the class of its own. Then the Tuna came along and surprised everyone. It is like a straight punch. Simple yet powerful enough to make an impact. In this case, our heart pumping. I strongly recommend all members to have a research on the tuna. It has the impact and effect similar to ipad, and this happened so many years ago...
