Seiko Presage Arita Porcelain SPB497J1 – 40.6mm (Limited Edition)

The SPB497J1 is a true statement of Japanese craftsmanship – and a very special piece within the Presage Arita line: The dial is made of unglazed Arita porcelain . This is precisely what makes this watch so exceptional, because unglazed porcelain is unforgiving. Every step of the manufacturing process must be perfect, every surface flawless, every contour meticulously crafted. Working closely with master porcelain artisans from Arita, the result is a dial that is not only "handmade" but also feels that way: serene, clear, and high-quality – with a subtle, natural depth that simply cannot be achieved with lacquered or glazed dials.

Master Hiroyuki Hashiguchi
The SPB497J1 isn't just about "Arita porcelain"—it's about a specific person behind this dial: Master Hiroyuki Hashiguchi . He's the porcelain master from Arita who handcrafted this unglazed dial. And Seiko does something here that's rarely seen, even in this price range: Hashiguchi is named on the watch's hangtag/label, something more commonly associated with luxury cars. This isn't a marketing ploy, but a genuine statement of quality—because it shows that this isn't just a piece of material being used, but that a master craftsman stands behind his work.

This is especially crucial with unglazed porcelain : the surface cannot "conceal" imperfections; nothing is visually smoothed by a glaze. Every nuance, every texture, every perfect stillness in the white arises from experience, control, and an incredible amount of dexterity. You sense this very craftsmanship when you move the dial in the light: not loud, not shiny – but still, profound, and extraordinary .

Inside, the automatic 6R51 movement with up to 72 hours of power reserve keeps time – a modern, robust Seiko base that perfectly complements this deliberately minimalist, handcrafted design. In short: a watch that doesn't need to be loud to make an impression – and as a limited edition, it also carries the allure of rarity.
