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

Bought this as a gift for my husband’s birthday and he LOVED it! He bought another strap tho because the original one is thin

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.

The description "red" can be misleading while the center is red, the edges are dark which match the brown band very well! Very nice color balance! A pro did this.

The brown sunburst changes in the light very well. You can definitely tell it’s not like the cocktail model. The clasp is an okay design. I’d much preferred if they did a butterfly clasp but since the bronze is PVD it wouldn’t make sense. It does enable many wrists sizes to wear it and I’m sure it will look good for any occasion. Look closer at the dial and you’ll know exactly what I mean. It is automatic and not COSC certified so take it for what it is. A breathtaking time piece that will make you want that Grand Seiko!

The face is beautiful. It would be best to look in the daylight to see the complexity of the design but simple at the same time

The only problem I have with this Presard is that I didn't learn about them sooner. Awesome time piece!

The good Beautiful dial pretty sun burst and fits on the wrist well. The strap with the deployment buckle is good as well. The bad. Since it is an automatic movement it is not exact and don’t expect it to be. Final thoughts It’s a good dress or office wear watch and worth the money.
