I bought the ISO401 about three months ago, and it's become my favorite wrist watch. And I have a LOT of wrist watches, and over the years have owned even more.
Normally, I wouldn't dream of preferring a quartz over a mechanical, mainly on principle. Even so, this is the watch I now wear every day. Frankly, I'm not crazy about the red accents on the dial, and would have preferred the case to be all black. But I've learned to accept the dial's style; I can see the time instantly, without having to stare at the hands. Everything lines up properly. And it really is bright, much brighter than my T25 watches, and helps visibility even in only slightly dark conditions. At night it's practically a source of light all by itself. The strap is very comfortable, and long.
Accuracy is virtually perfect: about half a second in three months. None of the mechanical wrist watches and pocket watches I own even come close--not even a couple of Bulova Precisionist movement watches I own.
The watch also seems to be very durable, and my experience dealing with ArmourLite has been very positive in every way. All things considered, I would definitely buy another one.
