Featuring a magnified date calendar and LumiBrite hands and markers, the dial is framed by a black ceramic uni-directional rotating elapsed timing bezel.

    • King of $500 Divers (UPDATED)
Color: White - SRPE37
Review Image by ASChin
I was looking at sub-$1000 divers for a couple of months. Ended up going down the Seiko rabbit-hole and discovered the King Samurai. The list of features at this price shocked me: Sapphire Crystal, Ceramic Bezel, Bright (if somewhat short-lasting) Lume, 200m, White Dial. Nothing in this price range (aside from Baltic) came close. Plus there's something cool about this chunky, old-school Seiko aesthetic. It's not trying to be a Rolex Sub or a Tudor or Omega. It's very workmanlike in its design -- ESPECIALLY if you pair it with a Crafter Blue dive strap. For an extra $65 or so you can take this good watch and make it look great. I've had this beast for less than a week and have already dinged it slightly -- however this is one of those watches that looks better with some character. I smiled when I saw the little dent. Added Bonus: my watch arrived with a "Made in Japan" dial and a perfectly aligned bezel. Three cons so far: 1. Seiko 4R movement runs around 10 seconds fast per day and only has around 40 hour reserve (at this price that's reasonable) 2. Screw down crown can be a bit gritty at times 3. Gripping the bezel isn't easy with the stock strap and very tough with the Crafter Blue upgrade. Overall I'm thrilled with this stylish yet blue-collar diving beast. Guess we were made for each other :) UPDATE: As much as I LOVED that Crafter Blue strap from an aesthetic perspective -- the rubber irritated my skin so much that I went back to the original Seiko strap. I'm so glad I did. The experience reminded me of just how comfortable these Seiko rubber dive straps are. No irritation whatsoever and the band expands nicely during times that my wrist swells. So yeah, this watch is even better value because you can't go wrong with the included strap. ... show more

This is a very quality watch. Feels solid and very comfortable on the wrist. The face is really intricate and aesthetically appealing. Size isn’t too big or overbearing, sits just right. So far the accuracy is great. I’m really happy with the purchase. The shipping was FAST!!

This watch is incredible. Movement is smooth, face is highly legible in all conditions, lume is even brighter than I knew lume could be. You can truly put it on once and very rarely take it off. I can’t say enough good things about this watch. The time it’s keeping is also unbelievable. I set it once a week on Mondays, and will be ±10 seconds by the END OF THE WEEK. That means this watch punches FAR above its weight class as far as accuracy goes; with stats like that, it very easily approaches COSC compliance. Finally, just look at the face. The physicality of it is stunning; each tile-like cutout catches the light beautifully in all lighting conditions. If you’re into watches, buy without hesitation. It’s some of the highest quality-to-cost on the market. ... show more

    • Robust everyday white dial diver
Color: White - SRPE37
Fast and good delivery. Came with own box and plastic protector wraps back and front. Seiko King Samurai White Dial is a robust 200m diver watch, dial pattern is good and increase readability, design is not for everybody but if you like it it wear smaller then dimensions due to unusual lug design. good finishing around the case and a very good everyday beater for price point. Silicon band is comfortable and I think watch would be too heavy with metal bracelet and weight distribution would be uneven with a nato, design would not fit with a leather. Happy with the purchase overall and would recommend it if you like the king samurai design as ceramic insert, overall finish and reliable mechanism around $400 makes this a price performance and robust watch. ... show more

    • The watch the has sparked an interest in owning more seikos.
Color: White - SRPE37
It’s a beautiful watch. Value for money is the best there is, easy to read, and supremely comfortable. It has become one of my favorites to just wear while doing pretty much anything outside of a situation requiring something more formal. Sized as though it was made for me, and shows very little wear with consistent use. ... show more

Beautiful watch. Sapphire glass, ceramic insert bezel, screw down crown and reliable automatic 4R35 movement. This beauty is fully Japan made which is an added value over pieces assembled in other countries. Bezel’s pip aligns perfectly at 12 o’clock. Cyclops, waffle dial, golden tip on seconds hand and exposed inner ring on bezel are nice details along with the different textures in the crown. I love this watch. ... show more

    • Quite nice at this price point.
Color: White - SRPE37
Overall, I'm very pleased and would buy again if priced below $425. The watch is an automatic with 23 jewels. It loses approximately one minute per week, which I find to be quite acceptable. Sapphire crystal helps prevent scratches. Some do not like the metal sleeve for the band saying it slides. I had several black silicone sleeves for another item that I simply placed in front of the metal sleeve. Blends well with the band color and keeps the metal sleeve in place. The numbers are luminescent to a degree. You can see the time in the dark for the first hour or so. I wish it had tritium inserts like a Luminox, but I am happy with the watch. I gives me a nice, business casual watch for when I don't want to wear my Apple Watch or something more dressy with suits. It finds a happy middle ground. ... show more
