Best In Class Seiko Watch
I am a watch collector and have a keen interest in classic watches. This is by far Seiko's best watch in a long time. This is classic yet elegant, a perfect balance between modern and retro style. The leather quality is very good, and the dial size is apt and would suit most wrists. The accuracy of the watch is pretty good, I would say, and I have been getting almost 70 hours of power reserve. You would not go wrong with this purchase.

Have been eyeing this for a year for my husband. Watch enthusiast! It was perfect. Just like the picture. There are some complaints about the band. He felt it was stiff but tried to soften it up but he will probably get another metal band. Beautiful watch.

This the real deal.. It is pricey, cant comment on the things i gave only 3 stars because I dont wear it much because it is so beautiful. A work of Art. Hey, it is a Seiko,,,it will last and can be repaired for 20 years after manufacture. And it will hold its value, I sent a 20 year old divers watch in to Seiko and they still had the parts for it, It puts Rolex's to shame. So does grand Seikos, I do own a gold Rolex and the case is all gold

This was probably last good Seiko available online at a decent price. After March 2023, you won't be able to buy a good Seiko at a reasonable price on Amazon. There are importers who are charging twice (even e times of actual market price) the amount these days online. Please avoid online shopping to buy good watches.

Beautiful, piece of art, the compass I couldn’t understand how it works :) , even I viewed a lot of YouTube videos explaining it.
