## Description

Black dial. Silver-tone stainless steel case with a silver-tone stainless steel band. Automatic movement. 30 meters / 100 feet water resistance. Fixed bezel. Fold Over with Push Button Release clasp. Case size 38 mm x 11 mm. Seiko SNK381 Seiko 5 Watch. From Humble beginnings, Kintaro Hattoris Vision for Seiko has become reality. A consuming passion for excellence - imprinted in our Corporate DNA passed from generation to generation. Seiko, for 125 years committed to the art and science of time. A culture of innovation connects a 19th century Tokyo clock shop with 20th century advances in timekeeping to an extraordinary 21st century "quiet revolution." Continually driven by dedication and passion, established a multitude of worlds first technologies transforming the principles of timekeeping. The first quartz wristwatch  changed the history of time. The first Kinetic  marked a new era in quartz watch technology. In 1969, Seiko Astron, the first quartz wristwatch - was introduced. In an instant, Seiko exponentially improved the accuracy of wristwatches And Seiko technology firmly established todays standard in Olympic and sports timing. 1984, another celebrated first  Kinetic Technology  powered by body movement. Kinetic  a quartz mechanism with unparalleled accuracy the driving force behind more worlds firsts. Kinetic Chronograph  the next generation of high performance timekeeping. Kinetic Auto Relay  automatically resets to the correct time. Kinetic Perpetual - combining the date perfect technology of perpetual calendar with the genius of Kinetic Auto Relay. And now Kinetic Direct Drive  move, and the watch is powered automatically. Or hand wind it and see the power you are generating in real time. In the realm of fine watches, time is measured by Seiko innovation  A heritage of dedication to the art and science of time.

Review: Rugged and/or dressy - First things first, as stated by nearly everyone else, change out bracelet for a band. Just like the “MACV SOG” it’s 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.
Review: 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.

### ⭐⭐⭐⭐ Good value on a classic design
*by F***N on May 27, 2025*

It is a good dependable watch. I like that plain classic look and numbers rather than indices. day/date windows are easy to read. It keeps time well has only gained or lost 5-10 seconds per week. Have worn it everyday since I bought it. I changed the wrist band so I can not review that. It has been wet from dunkings in dish water, rained on while on bike, has not shown any signs of moisture inside. The cristal has no scratches on it even though it has been banged on door frames. The lume is good and last longer than stated. August 2 2025 Six months update Have been wearing this watch almost exclusively when not at work. Fabulous watch after six months it has lost/gained 8 seconds and stayed in that margin of area since I put on. The watch was accidently along with its owner submerged in water upto 6' deep when I was out on a hike and the ledge I was traversing gave out and I slid/fell into a small river, that was in June. Took it to the horologist to have it looked at and it did not leak at all. Took these pics today. Will update as needed.
