Good looking watch that makes everyday wear a pleasure
I bought my first Seiko watch over fifty years ago, and it is still running. I bought this one since my old everyday watch was showing a lot of wear, and chose this one due to its name and its appearance. I was very pleased when I opened the box and took this watch out. It did require a little adjustment in the band size, but that process was very easy and very intuitive. Since then, this watch has lived up to its expectations and I am very pleased to wear it around the house every day. And I was pleasantly surprised at the price for this beauty. I many have to buy another one in another 50 years!!!

Mechanical Watches are for Wonder; Cell Phones are for the Exact Time To the Second
I've had this watch for about two weeks now, and so far it has performed flawlessly. It took a little drop with no ill effects, and I bumped it on the door while carrying an old CRT TV, again with no ill effects. It keeps time almost as accurately as my Seiko quartz watch and/or the clock on the cell phone. I have had to set it a couple of times as it ran down on the days I didn't wear it. A full winding seems to last somewhere in the neighborhood of 24 hours. Reading some of the other reviews of these watches, I thought it might be really junky, but so far it has performed like a champ. Only time will tell if it has longevity or not, but for the price I'm really happy with it. Oh, and I think it looks great too. After reading the other reviews I was afraid it would look and feel really cheesy, but it doesn't. I really wanted a vintage blue faced watch, but they were all too spendy for my blood. I was looking for a watch to wear daily that might get knocked around some. This watch is very nice looking and has a nice heft to it, which I like. I adjusted the band via the clasp with a paper clip, and that took about two minutes. I'd say give the Seiko 5 a whirl. I'm glad I finally did.

Seiko 5 automatics are awesome!
This was a gift for my oldest kid. It's my 3rd time buying a Seiko 5 automatic movement watch. Love them. Styling and reliability are great.

Good quality for the price.
The blue face on the dial looks nice. I have a small wrist and the 36mm size fits perfect. I don't like the big watch trend. It runs a little fast but you can take it to a jewelry store and adjust it for you.

What I expect from Seiko
Like:For an automatic, the one I got has excellent accuracy. I don't have exact numbers, but I suspect mine loses less than 5 seconds a day.The stainless & blue esthetic. Love that look.Don't like:Granted, I'm pretty hard on my watches, but for some reason the Hardlex crystal got scratched soon after I bought it. I have another ~30-year-old Seiko that I wore daily that took a beating much more gracefully. I hope what I have isn't a fake or 'refurbished' as it was purportedly genuine and new.

Looks like a cheap knock-off
I've owned a couple of nice Seikos in the past and when I saw the picure and price on Amazon I thought...wow what a nice watch and a great deal. After opening the box which didn't even come in Seikos trademark blue stamped box....this one was a generic black box with no Seiko booklet. I was disapointed to find a lightweight, rattle sounding band, cheap looking watch. It's not horrible but I would pay $50 off the rack at a discount store. I'm returning it but I have to pay $10 for a restock fee plus my shipping back to them.

Seiko Reliabilty
This watch replaced my previous Seiko 5 which lasted for 26 years. These are wonderful watches, self-winding; put it on each day and forget about it. They need servicing every five years or so but they keep great time and are trouble-free. This one is very attractive looking and has a high-quality stainless band. If you need to adjust the wrist-band length, there are YouTube videos that show the various types of Seiko bands and how to adjust them. It only took a few minutes and a little care.

Gran relación calidad precio
Muy bonito. Ideal para fans de los relojes sobre todo automáticos. La correa que viene es bastante grande, pero se puede ajustar en cualquier relojería. La esfera es algo pequeña si tienes la mano grande. Pero en relación calidad precio, es insuperable.
