Seiko Dial Markings Note:
This Seiko watch has a "K" suffix, meaning it's built for international markets and assembled at Seiko's quality facilities outside Japan (e.g., Malaysia).
That's why the dial lacks "Made in Japan" or "Japan Movement"—standard for these models. It does not impact authenticity, quality, or performance.
