SEIKO SRPG21 Automatic Dive Watch for Men - Prospex Collection - LumiBrite Hands, Magnified Date Calendar - 200M Water Resistant

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.

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.

Having followed a couple of 'influencers' on You Tube, I ordered this watch knowing that Seiko's QA has slipped over the past few years. Would I receive one with the dreaded misaligned bezel? A grey market? A knockoff instead of the real thing, especially at 25% off the list price? All I can say is this: If it's a knockoff, it sure has me fooled. Both the case back and the dial indicate the watch is made in Japan and the bezel aligns perfectly with the markers on the dial. It is a gorgeous, perfectly proportioned watch, and pictures do not do the work-of-art dial justice. Crown is large, easy to grip, and makes winding (when necessary -- this is an automatic) and adjusting the date and time a breeze. Lume is outstanding, definitely the winner of the 'lume wars' in my modest collection. I'm finicky and usually do not prefer date complications on a watch and typically do not like a cyclops on my crystal, but they are executed with aplomb on this Seiko and give it a Rolex-esque vibe while maintaining the classic Seiko style. The high-quality silicone strap is soft and supple and is thankfully not a 'lint grabber' like some silicone straps. 120-click bezel feels oil dampened and is second only to my much more expensive Oak and Oscar in quality and feel. Finally, losing less than a second per day, this Seiko is my most accurate mechanical. To sum up, I like this Seiko Prospex so much that (1) I bought an identical one for my nephew as a graduation gift, and (2) it's all but cured my watch jones (for now). If you're on the fence, have no fear. It's the real deal and it's a real winner. Definitely best-in-class at this price.

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.

Me encanta es mucho más hermoso que en las fotos, súper cómodo y aparte se ve increíble, lo compré con buen descuento y es uno de mis Seiko favoritos

I was looking for a reliable sapphire glass automatic that was value for money I had heard good things about the 4R35 caliber as having decent accuracy. I also wanted a magnified date window on a diver styled watch with a good lume. At the end of my search, I came across this King Samurai Manta Ray with the blue silicone strap and brought it on Amazon. This was my first blue dial watch face and I wasn’t sure I would completely like it. When I it arrived, I was a bit skeptical the first two days as I did another round of research on it and looked at all the details with a magnifying glass . Although it wasn’t made in Japan, it was only loosing two seconds a day. Which was amazing! The blue Manta Ray watch face with the Samurai sword hand and lumi bright made it so easy to tell the time day or night. I absolute love this watch! What I noticed is that the watch seems to slow slightly more than two seconds by the end of the day when I take it off. Then, lying it flat at night seems to bring it back slight faster so that it averages about two seconds a day. I love the colour of the strap, but it does tend to come out of the metal holder when I swim or flick my hands after washing my hands. So I’m going to get a blue FKM replacement strap. Overall, I absolutely love this watch and it would be my general purpose watch for decades to come.

It’s amazing watch. This is my first Seiko and I’m truly enjoying it. I have watches which are way more expensive than this, but I can confirm this watch punches above it’s weight class in terms of price, fit and finish. I have had friends who doesn’t know a lot about watches to seasoned collectors. Everyone has appreciated this watch. It’s just such a good watch. One minor criticism is that dial is a little dark, so sometimes it is hard to see the Mantas. With that being said, the dial is absolutely stunning along with rest of the watch.

La construcción del reloj es muy buena. Los materiales se ven bastante bien. El calibre es de casa y bastante confiable. Por el precio considero que es una excelente compra. La versión japonesa fue la que me llego así que si lo recomiendo.

Title is a joke but the watch is really nice. I finally pulled the trigger on a decent, grown up watch. I got it today so it remains to be seen if it’s accurate enough. I’m happy about two things in specific. One, that it’s Made in Japan. Second, that it’s smaller than I thought by the reviews.
