SEIKO PRESAGE SPB445J1 ARITA PORCELAIN CRAFTSMANSHIP MEN WATCH

Seiko Presage SPB445J1 — Craftsmanship Series Arita Porcelain Watch

The Seiko Presage SPB445J1 is the Arita porcelain expression of the Presage Craftsmanship Series — the highest-tier application of traditional Japanese ceramic craft to a watch dial in the current City Chain Seiko range. The dial is a "Hakuji" porcelain — a piece that highlights the pure white colour of the porcelain material through an application of transparent glaze, creating a surface with a warmth, depth, and milky lustre that no painted, coated, or printed dial can replicate. Each dial is individually moulded and fired at high temperature through at least three process stages, and each piece is genuinely unique: the natural firing process produces small variations in surface — tiny dimples, minute dots, subtle colour variation — that are not defects but the marks of authentic hand-fired craft.

This particular expression is the 'Concentric' — the dial features a recessed concentric ring pattern around the centre and a recessed sub-register at 6 o'clock, both of which require exceptional precision to create from a material as delicate as porcelain. The craftsman behind the dial is Hiroyuki Hashiguchi, a master porcelain artisan from Arita, Saga Prefecture, whose workshop has been making porcelain since 1830 and has been developing dials with the Presage team for years. The deep blue hands and indices reference the traditional Arita colour palette — the blue-and-white aesthetic that has defined Arita porcelain since the 17th century.

Powered by the 6R5H automatic calibre with hand-winding, stop seconds, and a 72-hour power reserve, the SPB445J1 delivers +25/-15 seconds per day in a 40.6mm super-hard coated stainless steel case with dual-curved sapphire crystal and anti-reflective coating on the inner surface. The 24-hour hand provides secondary time zone reference. The see-through caseback reveals the 6R5H calibre at work. No date, no Lumibrite — the dial is the only reason for this watch, and it is given the uninterrupted space it demands.

Why You'll Love It

The SPB445J1 is the watch that makes the strongest possible case for what the Presage Craftsmanship Series exists to do. The Arita porcelain dial is not a premium finish on a standard watch component — it is the primary reason the watch exists, and everything else in the specification is in service of it. The Hakuji white with the recessed concentric ring pattern is one of the most technically demanding dial surfaces produced at this price point anywhere in the watch industry: the difficulty of working porcelain into the precise concentric geometry of this dial, the brittleness of the material at each firing stage, the uncertainty of the outcome even for a craftsman of Hiroyuki Hashiguchi's experience — all of this is present in the finished object, which is why the transparency of the hand-firing process is something Seiko discloses openly. At SGD 2,725, the SPB445J1 is the highest-priced Seiko in the City Chain range — and the most deeply considered.

About Arita Porcelain

Arita is a small town in Kyushu — Japan's third-largest island — that came to prominence in the early 17th century when clay suitable for fine porcelain was discovered there. Despite a history of over 400 years, this traditional craft has never stopped evolving in terms of materials and moulding techniques. Seiko's partnership with Arita connects the Presage Craftsmanship Series to one of Japan's most enduring and globally recognised ceramic traditions — and the blue-and-white colour palette of the SPB445J1's hands and indices is a direct reference to the aesthetic that has defined Arita ware since its inception.

The Seiko Presage Story

The story begins in 1881, when Kintaro Hattori founded a clock and watch shop in Ginza, Tokyo — the business that would become the Seiko of today. Seiko Presage was created to carry Seiko's finest Japanese craft traditions into the watch dial: enamel, urushi lacquer, arita porcelain, and cocktail-inspired artistry are all expressions of the same commitment to elevating the dial from a functional surface into a work of craft. The SPB445J1 carries that tradition forward at its most technically demanding and culturally grounded — a watch whose dial has a four-hundred-year heritage behind it.
