    • 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

    • The perfect 200m Diver
Color: Gradated Blue
Review Image by L-1011
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. ... show more

    • Hard-to-beat Samurai for the money
Color: Gradated Blue
Review Image by MJD from Sunnyville, Ohio
Review Image by MJD from Sunnyville, Ohio
As owner of a regular, black dial Samurai (SRPB51K1), this special edition (SRPF79) features a number of improvements such as a ceramic bezel insert, sapphire crystal with cyclops magnifier, finer and more consistent brushing applied to the "cheeks" of the case, better polishing applied to the case, better and stronger lume, and of course, the beautiful dial with the manta rays that appear to glide under the surface of the water if this was even possible. The dial is absolutely stunning! The contrast between the dial and lumed bits is striking, and the bezel delineated by thin stainless strips complete the look into a design that is unapologetically toolish while also packing some bling. All markers on the dial and chapter ring align perfectly. The bezel rotation has a very stiff action, much stiffer than I remember from the regular Samurai when it was new. This doesn't bother me as I expect to break in over time. The accuracy of the 4R35 movement is, as expected based on my several other 4R35 and NH35 pieces, outstanding. I wear the watch constantly except for chores around the house, and the watch runs exactly accurate as compared to my phone. On the time grapher, the watch runs at +7 seconds/day face up but because of its position dependency (befitting an inexpensive movement), on the wrist it averages basically 0 second per day. Let's be clear, it's not a COSC movement, but Seiko knows how to adjust these 4R35s and extract the most performance out of them at a fraction of the cost of a Swiss equivalent. It's super easy to adjust if need be, something I've done on the SRPB51K1 and which of course I wouldn't attempt as confidently on a mega-dollar luxury watch. I don't care too much for the silicone strap supplied with it since it's too long for my 7.25" wrist, so I wear it on a Seiko bracelet, Miltat bracelet (pictured) or inexpensive "leather" strap (pictured). In summary, much has been said about Seiko no longer offering value, but this Samurai is proof of exactly the opposite! My experience with Seiko watches and movements has generally been outstanding. ... show more

    • Super cool watch

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
