Very nice. Though as a graphic designer I find the fonts on the dial a bit too generic and the numbers on the bezel excessively bold.
Naming the watch after an event that took hundreds of thousands of lives (I lost 2 friends in Thailand) is beyond my understanding. Though Tsunami is basically just a noun, you should understand that very, very many people will think you could have just as well named it Genocide or something along those lines. Just my 2 eurocents.
