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.

Beautiful watch the band is a bit stiff
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.

Excellent watch, but not advisable to buy it on Amazon anymore
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.

My favorite watch by a mile.
An absolute masterpiece and a staple for any collection! As an intermediate collector with 18 mechanical watches, the Seiko Alpinist SPB121 is easily my favorite. Why it stands out: Versatility: It perfectly balances elegance and utility. You can easily dress it up for formal occasions or wear it daily as a rugged field watch. The Dial: The green dial is stunning. I am highly partial to green watches (they make up 90% of my collection), and Seiko absolutely nailed this shade. Value: At around $795, it is a significant investment, but the durability, beautiful finish, and dependable automatic movement make it an outstanding value. Highly recommended for both seasoned collectors and those looking for their first serious automatic watch
