Very good casual watch. Keeps good time. Instructions are available at Seiko.com. You will need the case to find the manual of instructions.

On first blush, watch is attractive and was easy to set. The band on this model is patent leather and leaves a lot to be desired. The reported accuracy for this model is not great but time will tell.

The brown leather band had come with cannot accommodate an Eight inch wrist. It's too tight even on the last hole

I can not say enough about this watch. It is easily the most beautiful watch in my collection. It’s definitely a head turner. The watch is accurate, has a smooth movement, it’s not too big or too small, and the way the light reflects off of the face is just stunning. It’s definitely a win for Seiko!

I liked the original straps as well, but had to try these green straps on it and definitely loved it. It is lighter than it looks, but super chic. In terms of accuracy, it hasn’t been long since I started wearing it but I can say it gained 5 seconds in 24 hours; that’s like the same performance with my tissot le locle powermatic 80

It barely holds power reserve! Also the blue color tone of the image is way different than the actual color you get. Retuned.

Bought this watch as a birthday present for a good friend. Had the opportunity to inspect it and I was blown away at the quality. The sun-burst dial is def one of the best I've seen. Love that it's mechanical/automatic. The deployment clasp is so convenient. It's also quite versatile for a dress/casual watch. Might consider getting one for myself. :)

This Seiko watch has a beautiful dark red dial, as pictured, with brighter but elegant sunburst effects in the light. A quality item. Watch strap adjusts for anyone. Price, seller's response to questions, and delivery time were all reasonable. Good experience. Recommend. Thanks!

It was love at first sight for me. This green dial is phenomenal and after just three days of wearing it, I have lost count of the compliments it has received. IMO the wrist strap is poor. I also ordered a Barton replacement 20mm classic black leather with gold buckle and that looks and feels so much better than the stock strap. Many online reviews complain about the lack of the sapphire crystal (which is tougher than the stock) especially at this price point, but so far, so good. I'll primarily be wearing this when I am dressed up, which is not that often (I'm retired - no day job) so I am not that concerned. And really, if I (or you) wanted to, the sapphire crystals are not that expensive and could be easily added. This is not a diver so keep it as dry as possible. It is rated to just 5 bar so an occasional splash or a few rain drops should be AOK. Just don't shower with it. ;-) The users' manual is a download from Seiko. It is very easy to set (there are a few rules to follow for the date function) and after three days it has kept perfect time to the second. The second hand can be stopped so there are no issues to set to an exact time. It is automatic but can also be hand-wound (consult the manual) easily enough. I registered it on the Seiko web site - easy-peasey, for the three-year warranty. I absolutely LOVE this watch! It is my one and done for a dress watch.

For me, this is the best Men's dress watch under $1000. I really like the iconic design. Overall, the face is bright and easy to read. However, glare gets in the way sometimes. Here, I just angle my wrist away from the light source to put the face in shade and it does the trick. The original wrist band I found a bit cheap and the clasp awkward. So, I replaced it with a black alligator skin leather band and the watch looks and feels much better. The jeweler confirmed he has heard many issues with the clasp-style watch band. I need wind it a bit daily and keep an eye on the time, but for the price that's fine with me. Overall, for me the watch punches above its weight class.
