J1 vs. K1 — Understanding the Difference

Seiko often produces both J1 (Japan-made) and K1 (export-market) versions of the same model.
The SSK005K1 is the K1 variant, assembled in Seiko’s overseas facilities under identical standards and using the same Seiko-manufactured components.

Key distinctions:

• J1: Dial and caseback read “Made in Japan.”

• K1: Dial omits that text; caseback lists movement and model codes only.

• Price: J1 models are typically higher priced due to regional distribution, not quality.

Both are 100% authentic Seiko timepieces — there are no counterfeit “J vs K” variants.

About Me

A few years ago, I set out to buy my wife a special Christmas gift — a luxury watch that captured how much she meant to me. I didn’t expect that search to spark something deeper.

What started as a simple gift turned into a full-blown fascination. I fell in love with the artistry, mechanics, and legacy behind great watches. Over time, that passion evolved into something bigger: this business.

When you buy from me, you’re not just buying a watch — you’re supporting a dream and becoming part of a story that started with love and turned into legacy.

Thanks for being here. Let’s keep time — beautifully.
