Seiko Prospex SRPC93 ‘Save The Ocean’ Samurai Dive Watch Review

Seiko Prospex SRPC93 'Save The Ocean' Samurai Dive Watch Review Wrist Time Reviews

In the last several years, Seiko‘s Prospex line of rugged sport watches has blossomed into the global hit it deserves to be. At one time, enthusiasts in the know but not in Japan had to quest after these affordable but well-built tool watches that were mostly available only in their domestic Japanese market. Seiko has now not only made many lines including Prospex available globally, but they have also made their vast watch universe easier for consumers to understand. The Seiko Prospex SRPC93 “Save The Ocean” Samurai reviewed here is a good illustration of Seiko’s current approach to its products and marketing. Solidly built, a solid value, and just plain fun, it’s also a great example of why people love the Prospex watches and even Seiko in general.

It might be helpful to start with some perspective on the Seiko Prospex SRPC93 “Save The Ocean” Samurai by viewing it in the context of Seiko’s various price tiers and genres. Seiko’s offerings are so wide ranging and numerous, it sometimes seems like a mini watch industry itself more than a single company. At the most affordable end, Seiko offers basic quartz and mechanical watches for under $100 such as many in the Seiko 5 line. Above that are notable watches like the popular SKX007 and Monster dive watches that sell for under $300. The Prospex line is positioned as more premium, with “professional specifications,” hence the name (from “pro specs”). Existing laterally to the Prospex sport watches is the Presage line for more elegant and “dress”-style watches. Seiko often treats each of these lines (and others) kind of like a brand-within-a-brand.

In the Prospex line are Land, Air, and Sea families. The dive watches in the Sea family are by far the most popular – and where this review is focused, of course. But this Seiko product tree continues to branch before we arrive at the Seiko Prospex SRPC93 “Save The Ocean” Samurai. Finally, there are collections within the mechanical Prospex dive watches, most famously represented by the distinctive case shapes that have been nicknamed by the adoring public things like Turtle and Samurai – even though Seiko does not use these handy monikers themselves and mostly uses cryptic reference numbers. It might seem like a complicated taxonomy that I have described, but it’s a lot more organized than it once was.

To me, the modern Seiko Samurai and Seiko Turtle are like brothers in the Prospex dive watch family. Comparing them is useful because many attracted to the affordable, no-nonsense, slightly quirky, but everyday-wearable Seiko dive watch personality will find themselves choosing between a Turtle and a Samurai. They are more or less priced the same, share a number of specifications, and are dive watches with a similarly chunky wrist profile – even if the measurements are not one-to-one and other elements of the designs are quite different, what they offer seems very similar. In the most representative, black-dialed, versions of each, we reviewed the Seiko Turtle SRP777 here and the Seiko Samurai SRPB51 here. New versions of each of these watches are often released together with more or less the same aesthetic treatment.

That is the case for the Seiko Prospex “Save the Ocean” limited edition collection. As other watch brands have done, Seiko has chosen to support a marine conservation charity to highlight its dive watches. There are actually a number of Prospex “Save the Ocean” collection watches besides the Samurai and Turtle, some of which appear to be Japan-only releases, and the brand will donate a portion of the sales proceeds to the non-profit Fabien Cousteau Ocean Learning Center. Fabien Cousteau is the grandson of the famous Jacques-Yves Cousteau and his organization has a mission “to raise awareness, educate, and inform all citizens of the world of ways to protect and preserve the planet’s waters and endangered marine habitats and marine life.” So it seems like a good arrangement for Seiko and for the environment.

The various “Save the Ocean” edition watches feature a blue dial with a neat horizontal pattern meant to look like a watery surface. Looking closely, one will notice that the horizontal lines are uneven, like ripples or small waves. The Samurai’s aluminum bezel insert design with its 15-minute markers works particularly well with the striped dial pattern, in my opinion, and it is in a matching sporty blue. The dial fades from lighter blue at the top to darker at the bottom, seeming to reference ocean depths – this is something seen elsewhere as well, but most famously on the Rolex Deepsea Sea-Dweller 126660 D-Blue we saw hands-on here. In order to further distinguish this edition as special, the bezel and screw-down crown are given a black treatment contrasting with the rest of the steel case. Overall, this version is similar in a lot of ways to the Blue Lagoon Samurai SRPB09 which we reviewed here, also with a blue dial.

The above linked-to Seiko Samurai reviews discuss the look, details, and wearing experience of the watch, and I recommend you check them out for more perspectives. That includes more on the steel bracelet that the Seiko Prospex SRPC93 “Save The Ocean” Samurai comes on. The bracelet is solid and high quality but has the underwhelming Seiko clasp that many have complained about before. I quickly swapped it out for a couple straps until I put it on the Barton Bands Elite Silicon strap you see in these pictures, and I have been more or less satisfied ever since. Thinner straps such as this also improve wearability by reducing overall bulk. The Seiko Prospex SRPC93 “Save The Ocean” Samurai with its fresh blue colors just begs for fun, sporty strap pairings.

    It’s a Seiko diver, that’s all that needs to be said, we already know it’s going to amass a greater following than Gandhi…

  • SuperStrapper

    I prefer the samurai over the turtle as my eye generally prefers more technical lines and appearances over organic ones, and the turtle’s case is just kinda blobby. The samurai also wears at its dimensions where the turtle wears bigger.
    A close inspection of the case shows that it’s not so immaculate, but it is pretty nice for the money.
    Hopefully seiko evolved further into matching date wheels and ceramics. Which in sure they will when they figure out how to scale them.

  • JosephWelke

    Good review, thanks! I’ve never quite understood how the minute hand reminded people of a samurai sword either. No curve, and it seems double-edged.

    I hate yellowjackets. Little foul-tempered rats with stings.

  • Independent_George

    Researching Seiko divers is how I found ABTW.

    Seiko divers are still the best value around. With all the aftermarket parts that are available, they are the Honda Civic of watches.

    • Berndt Norten

      My SKX-007 is about 7 years old and has been on snorkel and beach duty. It’s my everyday beater. No scratches yet. Worth every penny.

      • DanW94

        SKX in EFX….

    The Blue Lagoon review from 2017 piqued my interest in the Samurai case, creating a longing that simply had to be filled. I have no complaints wearing the watch and my only critique would reference the handset, specifically the Monster inspired hour hand.
    The new Samurai IMO needs a unique handset apart and different from the others, something that highlights the angular case perhaps, keeping the heritage but set apart from similar brand offerings. Other than that, the watch is near-to perfect.
    The Save The Ocean like my Blue Lagoon is well suited for the Crafter Blue strap, a well priced and equally well fitted rubber strap made specifically for the Samurai series.

  • Hattori Hanzo (the real one) was a Samurai actually not a sword maker. In any case, I think picking up after yourself at the beach will do more to save flipper than buying this watch.

  • Bert Kanne

    One of the best new dive watch designs from Seiko, marred by one flaw, the lack of a sapphire crystal. An alternate model with a sapphire crystal should be offered, imo.

    • Tony NW

      With you. My Cocktail got nicked quite quickly. No more >$200 watches with plastic lenses. Ever.

  • Larry Holmack

    Nice enough looking, and the blue dial is really nice…as I have a thing blue dials. But… I am not really looking to yet another dive watch to my collection. I am selling off a few that are not in my rotation anymore…but I have a different Seiko in my sights.
    Nice article Zen…! Just wish a 44 mm watch looked that nice on my giant sized wrist.

    • egznyc

      What Seiko is in your sights? Sounds like it won’t be a dive watch … maybe something dressier?

      • Larry Holmack

        Yeah….and it’s much smaller than I usually wear…but I have been drooling over the Presage, SARD006. I have been wanting this watch since I saw it in a flyer my jeweler gave me the last time I was there getting a battery replaced. He told me that he could give me a nice discount on the watch…so if I can thin out my collection enough… I could afford it and the wife wouldn’t have to know about it!!!

  • Mark

    Great review Zen. It was an enjoyable read. I picked up the SRPC91 Turtle version when it first released. I get so many comments/compliments when I wear it. I think Seiko hit the nail on the head by releasing updates versions of the Turtle and Samurai. For those who like curves the Turtle scratches the itch. The Samurai is perfect for those who like angles. I enjoy both! Although, correct me if I’m wrong, but didn’t the first version of the Samurai get the nickname from the shape of both hour and minute hands? The current version, Seiko went with the oversized arrow for the hour hand. Anyway, a great review of a great watch.

  • egznyc

    Wow – you know, with the lighting and color balance in that photo, it looks like a bronze-cased Samurai (which suits the blue very well). Seiko, if you’re listening …. 😉

  • John___B

    I have the SRBP99 (the PADI edition). Great watch for the street price of just over $300. The crown and bezel action are great (smoother than Orient Ray II watches, another cheap beater people like).

    My biggest annoyance of the watch is that the pip is just ever so slightly off to the left side. That is, when the bezel is lined up at noon, the whole bezel looks like it needs to be slightly more to the right. Looks the same in one of your pics here.

    This seems to be a common complaint for this line of watch. I love Seiko and don’t understand this small lack of quality control.

    That said, still a great watch for the price (and still wish it had a sapphire crystal).

    I get is 1/20th the price of my Submariner, so all in all, a great watch for the money.

  • Berndt Norten

    Perfect watch for the price.

  • Rob

    Picked this up for around $300 new during the holidays. This is my first automatic watch, and I really enjoy wearing it. It’s converted me away from wearing a smartwatch thats for certain.

    The only downside is that it’s acting as gateway watch drawing me into wanting more watches.

    Great photos as well! Made my morning seeing it here.

    • Independent_George

      It’s not a downside. Collect and enjoy!

    • egznyc

      Your first, really? Then again, you said it’s your first auto; perhaps you’ve owned hand-wound watches? 😉

      You sound like a seasoned enthusiast, as beginners usually aren’t referring to something as their “gateway” watch. Anyway, enjoy the ride!

  • AFAIK, the wave dial pattern is based on the throat grooves found in rorquals.
    And the Samurai got its name from the hands.

  • David

    Promised myself I wasn’t going to buy another Samurai as I have the Padi but those pictures………

  • otaking241

    That strap combo is absolutely killer–well chosen! Will have to pick up something similar in time for beach season (would the same strap work with the Turtle version, I wonder…?).

  • I like it. The Wristi shot with the honey bee is great! Thanks for the review.

  • DeepEye

    Lately I’ve became completely disinterested in the Seiko lineup, since none of their newer offerings is under 42mm. There’s not a single Seiko diver (or any other watch for that matter) that caters to smaller wrists.

  • Pete L

    Cool review. Love the textured wavy dial and colour scheme on this one, really suits the substantial but not too chunky case. I guess this wears pretty well with those lugs too although I think it looks a little top heavy with that thin strap. As with all Seiko divers this is great value and would make an excellent beach/holiday watch. The picture with the wasp is awesome!

  • Larry Holmack

    I’ve never had the gold plating come off of any of my watches….not even the Seiko that I bought in 1985. ( Which still have! ) But…then again… I haven’t owned less than 10 watches since I was about 13 years old…back in 1970!

  • Jordan

    What a great watch! And the blue strap makes it even better. Can you tell me which one that is and where to buy it?

  • What fresh hell is this?

    Being a popular Seiko I think the answer is “undoubtedly”.

  • What fresh hell is this?

    More reviews of the watches people actually buy please!

  • Jazzi Jazz

    I was attracted to the modern, angular design, which for me conjures up images of Japanese temples or maybe samurai head gear. The lines are angled and beveled in several dimensions. The side where the crown and crown guard sit is very cool and architectural. Also, the knurled charcoal edge of the bezel and the crown stand out and aren’t wasted.

    But, I’ve had the watch for a few months, and haven’t worn it. For my collection, that usually means, “you’re hesitating, so don’t wear it, and sell it as like new”. I bought it at the same time as an srp637. I knew I wasn’t going to keep both, and I had wanted the 637 for the stainless shroud, so I sold it in favor of keeping this one, but then I had regrets.

    The problem is that I think I prefer looking at it off the wrist than on. As I said, the crown side is spectacular (but you don’t see it), as are the face and the bezel, and the knurling and the dark treatment works well (as would matte stainless). The opposite side from the crown, I’m not crazy about at all. The gap at 9 o’clock is strange to me. I wish they hadn’t interrupted the brushed outer case. Also the gap is polished, very noticeable, I think brushed makes more sense.

    My second issue is the strap and end link combo. I don’t hate the bracelet, but the end link is very wide and long, so much so that it distracts from viewing the face. When I wear the watch, unless i’m looking straight down, wrist under my chin, I see my wrist most of the day from a distance, and see that disproportionately large stainless end link and especially the very long center part of it that protrudes 4mm to link up with the bracelet. that extra 4mm makes the end link distracting, long and not well integrated, and takes away from the face. Makes me think, all that space, and still the bracelet – end link connection looks disjointed, bulky. Add to that the fact that the dial and crystal appear inset, so it doesn’t pop out and steal the show from the glaring end link to bracelet runway, accentuated by the fact the bezel has a raised edge.

    Like others, I think they could done something different with the hands, that take you back to any monster or 5 sports you might have owned, not much difference. With this architectural rectilinear case design, more unique hands to mirror the design of the case would have been appreciated.

    I also love the yellow accents on the blue lagoon, blue + a splash of yellow would have worked so well here on the seconds hand, and maybe the markers or contour on the hands.

    The Samurai has a unique attractive design, there’s no denying that. But if you have a lot of watches, you might stop by a shop if you can and spend some time with it on the wrist viewing from angles you spend most of the day looking at it.
