    • Great at the right price
This is my favorite “winter sweater watch.” At the right price, this is just a good and good looking watch. If I had to critique it at all, I’d say the green face looks better in direct light than in shade. Without direct light on it, it looks very dark, even black. And the enlarging window over the date isn’t necessary. But the gold numbers and cathedral hands are amazing ... show more

    • Seiko tool watch
I love my watch. The compass is fun to use while I'm walking in the woods. I enjoy telling the time and looking at the beautiful dial. A great and iconic tool watch

I could not be happier! This has been the one watch I e wanted to add to my collection for some time now. I was so happy to find a lower price than retail and to have it arrive a full week before the expected delivery date. The unpacking process was so much fun too since I wasn’t sure if it might be a 1-1 clone. It is 100% authentic and absolutely beautiful! ... show more

Removed one star for the weird band clasp Not at all good for smaller wrists.

First off, know you will swap the band going in so you are not surprised. The face is very good looking, the green appears somewhat dark indoors but shines when it catches the light. The cathedral hands I like as well. This does have a sapphire crystal so it’s durable. Also has an exhibition back to see some innards. Some people don’t like the fish eye for the date window but it does not bother me as I may need glasses. The lume on the cathedral hands really pops when going from sunlight into a dark space. She does feel like a bit of a chunky girl so if you are of slighter disposition and don’t like the feel of a watch on your arm it may not be for you. As far as accuracy she’s been about ten seconds fast per day which I think was in the listed tolerances and is just part of a battery less life. Overall I like and would buy again. ... show more

    • I have to say I love this watch , accuracy is spot on , reserve power is nice!
Okay I have several self-winding watches, from a Omega Seamaster Ocean to a Seiko SKX007. I try to wear them all. The SPB121 is my latest. Things I like, it has kept great time from the get-go. The Sapphire crystal is another, the power reserve is impressive due to the 6r35 movement and hacking and winding .The only thing I am not crazy with is the band. This would be the perfect adventure watch with a band that makes sense. Seiko has a track record of putting okay bands on their watches, so I am not going to penalize them for what I know they do. So yes, I would buy it again. Keep on keeping time folks. ... show more
