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.

It’s a very well made watch. The dial is beautiful and looks high quality. The only thing that tells that this watch is “cheap” is the band. But a quick switch with a better strap or metal bracelet would do the trick

Love the look, quality and size of the watch. I know others dislike the band, but I love it. I like the clasp, fit, and the look. Yes, the band has a high sheen to it - the same as a pair of patent leather shoes, only in dark brown. Personally, I feel the band goes well with the polish of the case, and the brilliant dark green dial. I have a small wrist, and typically wear vintage watches - but the watch is not too large on my wrist, and the band works well.
