I'm a die-hard mechanical, 21 jewels Seiko man but I also wanted an occasional wear watch that would ALWAYS be running and ready to wear, so I bought this. It's chunky, the band is made to gun tolerances and it's accurate to about two seconds a week. The lume will light up a wall. I have small wrists but it still looks appropriate and was easy to size, plus the deployment buckle has two pin settings for fine adjustment. It's the best looking all around watch I've ever had. I can wear it to formal functions or go skin diving with it. The solar face charged it immediately but I left it in the sun all day to insure a year or two of running even if I become a vampire and must hunt at night. Buy this, and enjoy.
