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.

Purchased this as a dress type watch. Only wear it a few times a week as I don't want to beat it up. Have other watches for that purpose. Keeps time great! It gains about 1 second per day and I find that very very accurate for a automatic watch. It helps to understand how to store it when your not wearing it. If you have a watch that tends to be slow leave it flat on its backside when not wearing it. If your watch is fast, prop it on its side when not wearing it and that will help to regulate the time better. Very good quality watch. Very beautiful!

Love the look of this watch. I couldn't be happier. The dial, listed as "blue" in the product description, though looks white in the product description photo, in reality looks just like that photo, and has a hint of blue in certain light, which is perfect. Everything about the dial, hands and bezel, is classy and not over the top. The size is just right, even the look of the black strap, which many seem to dislike, is not an issue with me. Very happy with this purchase.

The watch I received did NOT have the Seiko instruction manual or any of the factory applied protective tape on its surfaces. Additionally, the back was scratched and the leather band was worn notched in the third hole which indicates the band was adjusted and it had been worn for some time. I was under the impression this was a NEW watch because of the price. Additionally, there were no comments to indicate the watch was used or a demo item.
