They are all “K” versions. Made in Korea. Not Japan.
I got a SNZ ”J” version and I like it a lot. Its about 2 minutes off after a month when taken of when sleeping. It’s build like tank. Bumped it sometimes against the “glas”. No scratches at all.
BassieAs boozed responded, the "K" and "J" are identical except for certain branding elements, like printing "Made in Japan" on it and having a different day disc. Seiko has been notoriously cagey about answering questions related to this, but the general consensus on the watch-enthusiast forums is that they are all made in the same factories (they make a lot of their watches in Malaysia or Singapore so the "K" likely doesn't mean Korea), and the different letters designate that they are for different markets. The "J" models are for the Middle Eastern market, hence most have a day disc in English and Arabic, and Seiko puts the company's country of origin instead of the product's origin. If it's important to you to have "Made in Japan" on the dial and it's worth paying the premium for it, then you should purchase the watch that makes you happy. Otherwise, they are essentially the same. Cheers!
