I purchased this watch back in November 2010, I've been quite happy ever since. I have a relative small wrist, so I rather not have the face of the watch to be bigger than 5 cm. This watch is measured little less than 4 cm and fit nicely on my wrist. The window is flat and the hardlex material seems to work pretty well; it has not had any scratch on the window yet. I think it been flat also help to avoid bumping into things as well. The band gets scratch a lot down at the opposite of the wrist, but it is expected. The design is quite stylish, I wear it to work and also during the weekend's casual environment. Since it is an automatic watch, it need to be wore pretty often to keep the watch going. I have it stopped couple times during the weekend when I forgot to wear it, however, by looking at the time it stops, it would have been running almost for 2 days before it stops (usually stops in Sunday night), which I think is pretty good.
Lastly, I notice it runs little fast. Every couple of month I'd notice my watch is fast by a few minutes, which isn't a big issue since it could be adjusted in 2 seconds. Also, after all, it is an analog watch and the reading of time is quite subjective anyway.
I would highly recommend this watch and any other automatic Seiko's.
