The blue face and bezel are almost jewel-like in certain lights. I'm of an age when we were taught in school how to use a slide rule, but, not being a pilot, nor a mathematician, I doubt I'll ever use this one. It is a thing of beauty though, and adds to the charm of the watch.
However, I do, and will, use the stopwatch function. Having time split down into twentieths of a second, and having the ability to time for up to twelve hours, is truly a bonus.
All in all, this is a very accurate, reliable (hey, it's a Seiko) timepiece. At 42 mm, it's comfortably sized for most people, (unless you are a fashionista hipster into wearing a dinner plate on your wrist... ) And it's beautiful.
