Which SSK003 Are You Getting? (J1 vs. K1 Explained) 

Seiko produces the SSK003 in two official versions:

• SSK003J1 – Japan-made version: Assembled in Seiko’s Japanese facilities, often marked “Made in Japan” on the dial or caseback. These versions usually carry a higher price due to origin and collectibility.

• SSK003K1 – Export version: Assembled in Seiko-owned facilities outside Japan (commonly Malaysia). The K1 is identical in movement, finishing, and materials but typically sold at a lower price.

Both versions share:

• The same Seiko 4R34 automatic GMT movement

• The same 42.5 mm SKX-inspired stainless steel case

• The same blue sunburst dial, red GMT hand, and Pepsi-style bezel

• The same stylized stainless steel bracelet

The only distinctions are:

• Assembly location (Japan vs. overseas)

• Minor dial and caseback text differences

• Pricing (J1 typically costs more)

Neither version is “fake” or lower quality — both are genuine Seiko releases made to Seiko’s rigorous standards.

This listing is for the brand-new, full‑set SSK003K1 export version.
