I've owned this watch for over two years and enjoy it more as time goes by. I have quite a collection and of all my watches this large Seiko is actually the most comfortable watch that I wear. My only complaint would be that the hands could be more distinctive for quicker viewing. The accuracy is unmatched. I may have reset the time twice in two years.

One of the best values I have found in watches. Great watch at a fantastic price hundreds off of retail! Case is resilient, I tend to be very rough on watches and this one has stood the test.

I've had this watch for a couple years and am very happy with it. The chronograph is very easy to use. The alarm is easy to use as well. There are two alarm sounds depending if the chronograph is on or not--very cool. The construction is very solid--quite heavy though. The metal band wraps around my wrist pretty well despite having small wrists. The rotating bezel is one more convenient feature. This watch is also just plain manly.

I bought my first Seiko Quartz watch about 20-years ago, when I was preparing to navigate my boat across the Atlantic using a sextant. The Seiko dive watch was intended to be a backup to my Rolex GMT-master, a certified chronometer. But the Seiko had such better accuracy compared with the Rolex, it ended up being my primary piece for establishing the time of my sun-sights. The accuracy was within about two seconds per month.

Over the last twenty years, my Seiko dive watch became rather tired and worn looking. The colours of the bezel are no where near as bright as they were when new. Then, one day, I took a shower while having left the screw-down crown open...and moisture entered the watch. The result was that the hands became corroded, and I couldn't see them anymore without my reading glasses....but the watch still kept excellent time.

So, wanting to buy a new watch, I got the Seiko SNA225 chronograph. It's absolutely gorgeous. It looks like a Rolex Submariner and a Rolex Daytona chronograph rolled into one. I've checked the time-keeping of the SNA225 over two days against the Naval Observatory website. So far I've seen no change in accuracy whatsoever.

The only possible fault with this watch is that the alarm rings about a half hour later than I set it, but I suspect this can be corrected by re-zeroing the alarm dial hands (if I figure out how to do that). In any case, I don't care. I never intend to use the alarm function.

One thing that did confuse me is that there seem to be two similar model numbers being sold, the SNA225 and the SNA225P1. As far as I can determine, they both have identical appearance and functions, and they both have the same 7T62 Quartz movement.

Just got my watch today in the mail. I read the reviews before making the purchase and I can say that I'm happy with the purchase. The only thing I don't love is that the band is a little flimsy. Overall, the watch has great weight, and it feels sturdy, but the band just feels a little light. Other than that it seems to be a really good watch. And I haven't figured out how to set the alarm yet, but I'm sure I will.
