If there is a SNK375J1 it is made in Japan, has "Made in Japan" written on the dial and is more likely to have Arabic as the second language on the day dial. Seikodidirikan pada tahun 1881 oleh Kintaro Hattoridi kota Tokyo, Jepang. Awalnya Seiko bernama Seikosha dalam bahasa Jepang, "Seiko" berarti "indah", "menit" atau "sukses" dan "sha" berarti rumah. Seiko merupakan lambang dari jam tangan yang presisi, akurat dan selalu berinovasi. Dengan semangat dan moto dari pendirinya yaitu “satu langkah lebih maju kedepan” Seiko semakin berkembang dan dikenal luas di seluruh dunia. You'll get your money's worth on even an entry level Seiko 5 like this one more often than not. However know up front, like I said, "ANY SEIKO 5 IS A CRAP SHOOT" in precision accuracy out of the box. They were intended to get some post sale attention eventually for a fine tuning. Accuracy to within one minute a week out of the box on a Seiko 5 is great based on my experience. Accuracy freaks will be better off staying away from any mechanical watch at any price. Mechanical watches are like people, they are all different with their little quirks, good points and bad points. Here you have a decent automatic watch that can last you a decade or two depending on how beat up it gets. I like Seiko 5's as a work watch and like this particular one more than the other Seiko 5's I have worn because this one looks old school and keeps the best time. Seiko 5 kebanyakan menggunakan mesin movement automatic 17 jewel, 21 jewel, 23 jewels, 25 jewels, dan sebagian kecil 29 jewels. Semakin tinggi jewels yang digunakan maka semakin tinggi nilai jam tersebut. Bahkan sudah ada koleksi Seiko automatic yang menggunakan hingga 50 jewels seperti pada koleksi Spring Drive. Jam automatic Seiko 5 kebanyakan dihasilkan dari gerakan spring (per) sekitar 28.800 gerakan per jam dengan tingkat akurasi sekitar 15 – 25 detik perhari. Gerakan inilah yang akan di ubah menjadi tenaga mekanis yang menggerakkan jarum jam.

Seiko 5's are not the best automatic watches in the world and nobody in Switzerland is losing sleep over Seiko 5's. However if nothing else Seiko 5's are very durable and since the technology isn't exactly groundbreaking they are super affordable. Translation, Seiko 5's are a decent watch that last a very long time even under rough use, yet relative to anything else that is as durable they are really cheap. In short a bargain if you get one that keeps time out of the box to within 1 minute or so per week. Di Indonesia Seiko 5 adalah jam automatic yang paling banyak penggemarnya. Jam ini dirasakan mempunyai nilai jam vintage dan sejarah. Secara tampilan fisik, jam vintage cenderung mempunyai aura klasik yang penuh wibawa. Seiko 5 Sports SRPF70K1 Naruto & Boruto Naruto Uzumaki Model Dual Tone Nylon Strap LIMITED EDITION Rp5.712.000There is a perfectly safe do it yourself regulation method that works for automatic watches called position regulating. For position regulating you put a fully charged automatic watch in a certain position and leave it stationary for hours, such as overnight. With the face up an automatic watch will gain a few seconds more than the normal rate during wear. With the watch on its side it will run a bit slower than the normal rate during wear so it loses time. With the crown (winding stem) pointing UP it will lose a few seconds more time than it will lose with the crown pointing down. Using position regulating like this helps, but if your watch loses or gains more than 10 seconds a day it won't help enough to keep it perfectly on time, but will help some.
