Sieko Men's SNK381K Stainless Steel Analog with Black Dial Watch

Among several Seiko 5s I have, I like this dial the most because it doesn't reflect light back. The matte dial enhances legibility. Not to mention that the dial feels less cluttered than for example the popular SNK809. But the handset isn't the best when it comes to legibility--if only it was paired with the same "all-white" handset found in the SNKN25 (or the older SNX809). But it still is probably the best choice among Seiko 5 'field-watch' options because the SNKN25 dial just has lumed "pips" (numerals are not lumed unlike with the SNK381), the SNX809 has a case that is polished everywhere and is paired with a white day-date that "swallows" the white hands (the hands gets "lost" when they go over the day-date), and the SNK809 isn't really a "field-watch" (as opposed to the SNX809 which is). As Seiko 5 watches go, this is a good one. And the item I received works well out of the box.

This is in my opinion is the best Seiko 5 for a watch collection. The applied Arabic numeral indices are fully lumed. The black dial with those numerals makes it super easy to read. Combined with the fully lumed leaf hands and lumed lolly pop second hand makes this dial a lume monster! It's just better than any other seiko 5. I appreciate the display back. The day/date window is large and nicely framed at the 3 o'clock. The crown tucks in nicely at 4 o'clock is not screw down but easily sets the time. The case size is small but the dial is so easy to read. The case itself and bracelet are nicely polished. The bracelet is cheap with folded endlinks. It is a pain removing links even with a watch tool kit. The clasp is cheap thinly stamped metal but functions perfectly. Once properly sized, bracelet is comfortable and does not pinch hairs on my hairy wrist. If you wear this bracelet loose it will pinch your hairs. I think this watch looks and feels great and is a unique addition to any collection.

Eighteen millimeters. Let's put that right up front, because there's bad info all over the net about this model for some reason. The lug width is 18mm. The strap/bracelet width to order is 18mm. Eighteen. Not 17, not 20, eighteen. 18. Eight, followed by teen. Get a 10mm strap, then stretch it 8mm wider. So this is a Seiko 5. So much has been written and said about these watches. It's all correct, except as noted above regarding the lug width. The lume is excellent, the dial is very, very easy to read, and I wish they'd upgrade the movement to have the features the NH35 has. Hacking is good. It makes it easier to set the watch accurately, although a bit of back pressure on this watch's crown accomplishes about the same thing. And handwinding is even gooder. That's my biggest complaint about the Seiko watches with this movement. If you have one watch and wear this all the time, it's not an issue, but if you have many and switch them out not being able to handwind is annoying. You don't know how much time you have left before it winds down, and the only way to wind it is to shake it, to wear it and be active. And that winds the mainspring a lot slower, less effectively than movements that can handwind. Okay, enough about that. The framed day/date window is a nice touch, especially at such a low price. The case is nice and slim, with comfortable contours and good finishing. The crown is too small. It's not the easiest crown to use. I won't use the phrase "change it if I could," because I can. But I don't want to, because the way it is it homages, it mimics the 1960s Seikos that were worn by some incredibly tough men fighting for others' freedom. It was a military issue item. Those are collectors items now. This is very, very similar to those watches; I can see it. The tiny crown means it sits very flush, so it won't snag. It won't dig into your wrist. It's safe and out of the way. So it stays. As you can see, I immediately swapped the steel bracelet for a NATO strap. I like the clasp on the bracelet. The end links integrate very well with the rest of the bracelet. That's about it. The overall design is too busy for my taste. Varying widths, varying finishes, and as you can see in one of the photos, it doesn't even move smoothly enough. You can see one of the links hanging up and sticking above the others. It shouldn't do that. But maybe they know how many people are immediately going to remove it and replace it with nylon or rubber. I don't know. I also don't know why they don't offer it with a nylon, military looking strap. Not a big deal. If you think you'd like this, and you understand the handwinding gripes, go for it. To SSG Walter Ferguson, Jr., still unaccounted for, we remember you and your MIA brothers, and those who returned from defending freedom to continue your lives. Thank you for your service.

Hands down the best watch I've ever owned! This is a watch inspired by the older “MACV-SOG” version used by the special Vietnam soldiers in WW2. I love its history behind it and it feels amazing on the wrist. Some people complained about the bracelet it comes with but i love the way it looks and feels with the original bracelet. I have changed the bracelet to a Nato Strap every once and a while but always go back to using its original. Its lume is AMAZING its so bright and easy to read at night which really surprised me.(in the video you can see it) i have now started a watch collection thanks to this watch and have fell down the rabbit hole of buying many watches but this one is by far my favorite one. I highly recommend you getting this watch before it sells out since they are no longer producing this model meaning once it sells out everywhere you wont be able to get it and the price will increase with time. Do yourself a favor and get it while you still can you wont regret it! Ps. Thank you to every single Veteran/Soldier for their service! 🫡

I love the clean, simple, look of this watch. The fully numbered dial makes it easy to check time at a glance, and thanks to the cheerful green glow of Seiko's Lumibrite, it's just as easy to read in the dark. No hacking or hand winding with the 7S26 movement, but plenty accurate and reliable if worn daily. 30 meter water resistance rules out swimming/diving but it's more than adequate protection against sweat, rain, or the occasional dunking that an everyday watch could be exposed to. As for the bracelet, I see folks removing it in favor of leather bands. To each their own, leather bands are comfortable and stylish. That said, there's nothing wrong with the factory bracelet once you resize it. More importantly, the stainless steel bracelet can hold up to working outdoors in the heat of summer without very quickly looking and smelling like the dog's chew toy. All in all an outstanding everyday watch that should give years of service at an affordable price. Nothing not to like with this one.

Notice the name is misspelled. This "watch" is not authentic. The model number DOES NOT EXIST on the official website. It cost over one hundred and thirty dollars, worked only five months with constant readjusting, and then died. No product support, return impossible after two months. WARNING!!! do not buy!

This was an anniversary present from my wife. I really like this Seiko watch! It's very accurate, it gains about 4 seconds a day. The illumination of the face and hands is adequate and lasts most of the night. It's very easy to read you can tell the time at a quick glance. I like the fact that the watch is not too big nor is it too small. Good Luck God Bless

I own a few Seiko watches including automatics, and love this style of this watch. It was just way too small. I do think I have a larger wrist, as I typically enjoy 42 or 43 mm cases. This seemed very small on my wrist. Also the bracelet is extremely cheap. I was already planning on replacing it with a leather strap, which is weird too considering it uses a 20 mm strap which in my experience is small, obviously this is related to case diameter. Attractive watch, could pass for a war masculine watch on a woman's wrist or perfect for guys with a smaller wrists. Do wish it was available closer to 42 or 43 mm.

C’est ma première Seiko, pour voir :) Je suis habitué aux automatiques suisses de milieu de gamme (moins de 1500 euros) mais je voulais tester une entrée de gamme à moins de 200 balles. Le rapport qualité prix est excellent. C’est une montre avec une très bonne finition et un mécanisme très honorable, pour le prix. Elle avance de 15 secondes pour 24h (elle fait mieux qu’une Hamilton 3X plus chère) La visibilité la nuit est bonne. l’épaisseur de la montre est acceptable, pour moi. La réserve de marche permet de tenir une nuit sans problème. Je n’ai pas testé plus de temps. Le seul point négatif que je lui trouve, pour le moment, c’est le bracelet. Très bas de gamme et qui n’inspire pas confiance. A remplacer par quelque chose de mieux (cuir pas exemple). Bref, bilan très positif pour cette petite montre pas chère mais très belle! A réserver pour des petits poignets. Je recommande si c’est ce que vous cherchez.

Sehr schöne Uhr Gut geeignet für schmale Handgelenke

Compra maestra. Mejor no lo compréis y así soy el único que lo tiene. Parece mentira calidad precio. ¿He dicho ya que es automático? Pros: Seiko y Automático, ¡Sumergible!, diseño con la corona a las 4h distinto a la mayoría, fiable - a penas me ha adelantado 1min en una semana, ligero, correa de metal mate/brillo, lumen muy muy luminoso, manecillas en forma de hoja... Contras: esfera pequeña - yo suelo tener minimo 40mm y aún así me encanta- fecha en inglés-árabe?, Cristal no es de zafiro -tampoco tendría ese precio- la correa cuesta ajustarla en casa por el diseño de los eslabones, el lumen no dura demasiado -aunque vale la pena por lo luminoso que es- la caja donde viene es bastante justa, una pena que no venga un libro de instrucciones o así que mejora el aspecto si es un regalo. Aún con esos contras es una compra maestra. Muchos foros lo ponen como un must de Seiko 5, incluso de la marca Seiko en general. Después de unas semanas me uno a esa afirmación. Modelo difícil de conseguir fuera de Amazon. A pesar de la caja y presentación donde viene, si es un regalo vaís a quedar como reyes.

Have had this almost a year and it's been keeping perfect time so far. A very good price for a mechanical timepiece at £99.00, although at time of writing this review, I notice that it's gone up quite a bit! Strongly luminescent for plain legibility in the dark, with the lume delicately applied to the silvery chrome of the numbers and fingers of the watch with a very satisfying precision. The "sword" shape of the fingers is not exactly what I wanted, but you can't have everything. The silver against the black dial is a very pleasing and stark contrast which again increases legibility (important to me because my eyes are not so good close up without my glasses). The large size of the numerals is a big plus in that department. The crystal is pretty tough as it's still completely without chips or scratches despite a good few knocks over the months I've had it (worn every day and all day). The metal wrist band goes well with the watch and is a very good fit after adjustment. It will probably last as long as the watch. Not waterproof, and not sold as such, but it's not going to stop because of rain or washing your hands. Just don't go swimming with it on, or take it into the shower! I like the simplicity of the design and the size. It's not so big that you are always aware if it, but it's big enough to be perfectly readable. The day of the week and the day of the month display at a decent size but do take out the number 3 from the dial display. The automatic wind will keep the watch going overnight and most of the next day, if you leave it off your wrist.

Underrated Watch. Perfect size for smaller wrists. This field watch has an amazing history (Vietnam War). The lume is excellent and accuracy +/- 2 seconds per day. I love it prefer to wear it over my Rolex explorer.
