Great everyday wear watch
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.

I’m a collector and this watch is legit!
Ive been a watch enthusiast for a long time and it’s kind of funny to me that I’m just buying my first Seiko 5 after all these years. I got this one because I love thedial design, which dates back to the same model worn by troops in Vietnam. It looks tough on a NATO or rubber strap, but dresses up nicely on leather. Honestly, it kind of gives me a vintage Rolex Explorer vibe. The fact that its only about $100 means I don’t worry at all about banging it around, but I still know I’m wearing a quality automatic watch. The applied numerals look fantastic and have more powerful lume than any swiss watch I own. Seiko is king of lume. It does wear a little small at 37mm, but it’s perfect on my wrist. Comfortable and unobstrusive. Like most Seikos, it looks and feels like a more expensive watch than is. I just got this and I can see it being my daily wearer for a long time to come. If you want vintage vibes in a watch that has a actual vintage history, this is a really solid choice.P.s. The bracelet it comes with is terrible. This watch is a strap monster and looks infinitely cooler when it’s on a NATO or strap.

Classic Seiko 5 goodness, with MACV-SOG vibes
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.

Rugged and/or dressy
First things first, as stated by nearly everyone else, change out bracelet for a band.Just like the âMACV SOGâ itâs modeled after, this watch performs amazingly as a rugged field watch, but dresses up nice for formal wear as well. Recently purchased this with a leather band, wore it with a suit to a wedding, and aesthetic was perfect.No complaints on function or movements on this watch. Accuracy seems to be there with little to no change from day to day. Lum works as designed. Comfortable size, not too small, not too big. All in all, great watch, favorite one I now own.

Nice Lumed Numerals and Matte Dial
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.

Câest 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. Câest 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 quâune Hamilton 3X plus chère)La visibilité la nuit est bonne. lâépaisseur de la montre est acceptable, pour moi.La réserve de marche permet de tenir une nuit sans problème. Je nâai pas testé plus de temps.Le seul point négatif que je lui trouve, pour le moment, câest le bracelet. Très bas de gamme et qui nâinspire 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 câest ce que vous cherchez.

Forse il miglior Seiko 5 a tema militare di sempre! Questo orologio è visibilmente un omaggio al Seiko 6119-8100 degli anni ’60, che fu utilizzato dalle Forze Armate USA. Si tratta di un “field watch” in piena regola, con quadrante nero super leggibile e linee minimaliste. I numeroni sono applicati (in rilievo) e ben fosforescenti. Tutte e tre le lancette sono fosforescenti (veder muovere quella dei secondi al buio vuol dire avere la conferma visiva che il movimento è funzionante). La cassa è ben fatta, con forme morbide ed una elegante bisellatura che corre sui fianchi. Le dimensioni sono molto compatte, con un diametro cassa di 37 mm, un ingombro polso di 41,5 mm ed uno spessore di 10 mm: di fatto adatte a qualsiasi polso. La corona posizionata a ore 4 e parzialmente annegata nella carrure non da fastidio al polso ed esalta la simmetria della cassa. Il fondello è avvitato e trasparente, e lascia intravedere il movimento; quest’ultimo è il classico meccanico automatico Seiko 7s26, di certo non precisissimo né supersofisticato ma robustissimo, dalla manutenzione poco costosa e dotato di un sistema di ricarica bidirezionale molto efficiente accoppiato ad una molla da 41 ore di autonomia. La resistenza all’acqua è di 3 Bar, sufficiente per resistere a lavaggio mani, pioggia ed eventuali schizzi di acqua ma non immergetelo in piscina o al mare perché non è il suo mestiere. Unica pecca il braccialetto di acciaio, esteticamente gradevole ma dalla consistenza un po’ leggera, che consiglio vivamente di sostituire con un cinturino in cuoio o di tipo NATO che ne esalta l’anima militare vintage (la larghezza dell’ansa è di 18 mm standard, quindi trovare un cinturino adatto non è difficile). Ultimo ma non ultimo si tratta di un field watch che a differenza di molti modelli in questo settore non imita nessuno dei soliti noti, in quanto ha la sua storia e la sua personalità . Nel complesso promosso a pieni voti!

Muy buen reloj, carátula única y muy luminosa.No hay mejor relación precio calidad que la que ofrece la serie Seiko 5 sobretodo en sus modelos clásicos.Excelente acabado del cuerpo en acero inoxidable, cepillado y contraste pulido de gran calidad. La corona a las 4 menos 15 es muy cómoda en la muñeca. La carátula esta muy bien acabada con Ãndices de acero con luminosidad generosa que permite ver la hora durante toda la noche. El brazalete es de acero laminado y doblado lo que lo hace ligero pero es el punto débil del reloj, aún asà es muy cómodo y esta bien acabado. El mecanismo es el 7S26C , automático sin cuerda manual ni hackeo pero muy confiable y duradero ya que no requiere servicio por un par de décadas. No es muy preciso de fabrica pero muy fácil de regular. Este movimiento automático ya regulado me marca +3 segundos por dÃa y corona abajo en la noche marca -2 segundos asà que ha sido regulado a un estándar muy bueno, eso si, hay que usarlo regularmente ya que estos mecanismos varian su precisión en función de su carga de cuerda, es decir, su consistencia de marcha es variable, pero si se usa regularmente se tiene un reloj totalmente confiable. En resumen, por el precio, no hay mejor opción en todo el mundo, además hay modelos para todos los gustos. Este reloj en especial es de tamaño tradicional (37mm) y va de maravilla en muñecas medias de hombre y hasta va bien para Dama. Su estilo es tipo âfield watch or pilot watchâ por la apariencia de la carátula. Estos modelos clásicos de Seiko 5 están siendo remplazados por la nueva serie 5 (tipo skx) asà que hay que comprarlos mientras estén disponibles ya que las series nuevas son muy caras y no respetan la tendencia clásica que tanto éxito tuvo. Asà que totalmente recomendable este Seiko 5 SNK381 y en general toda la serie SNK.
