Mechanically, it seems to keep time very well with very little deviation. I think adjusting the time once a year would be all that was necessary to keep it within a minute of the original set-time. Also, as I think someone else pointed out, the second hand does not move normally. You must use the button on the side of the watch to start it in motion; when doing so, the watch behaves much like a classic stopwatch - it's even capable of giving split times. Similarly, the chronographs only function when this stopwatch action is in use.
As to style, the chain-link band is very unique and very tasteful, in my opinion. I have received numerous compliments on my watch and more than a few inquiries as to what kind of watch it is or how to get one like it. Every element of the watch face is very well designed, aesthetically speaking.
Regarding comfort, I must admit I've lost a few hairs on my wrist from time to time (pun intended), but I must add that the number has been notably fewer than those lost to other metal-style bands. Adjusting the band to accommodate your wrist is quite simple to do, and, once adjusted, it conforms the wrist quite nicely and does not stick out on the sides as some stiffer bands may do. It is very lightweight as well, and, given its thin profile, does not snag as easily on shirt or jacket cuffs.
All in all, it's a really classy piece that functions beautifully.
