How a Seiko Arita Porcelain Dial is Crafted

Authored By DePaula Jewelers

A multi-stage
production process

  • 01Molding

    To produce the dials involves a challenging combination of skill, patience and artistry. First, the base material is put into a special mold which gives dials depth, especially in the version where the power reserve indictor is recessed into the dial with a deep cut.
    The dials are dried and then fired for the first time at 1,300 degrees to harden and whiten the material.

  • 02Glazed/Fired

    Hashiguchi and his craftsmen then apply the glaze by hand, after which the dials are fired again, this time cementing the glaze on to the dial, a process which gives the dials their deep, rich finish and the subtle blue tinge.

  • 03Finishing

    Next, the holes for the date window and hands are cut by laser. Finally, the dials are then fired again to render smooth the surfaces that have been cut.


Two interpretations, one with a new extended power reserve caliber.

This Presage series comprises two interpretations of the design, both of which are powered by Seiko’s high performance 6R series calibers. SPB093 offers caliber 6R27, with a power reserve indicator at the nine o’clock position and a date indicator at six o’clock. SPB095 offers a new caliber, 6R35, which delivers a power reserve of 70 hours.
The crystal glass is a dual-curved sapphire, the exhibition case back reveals the fine finishing of the 6R movements and both versions are 10 bar water resistant. Straps are crocodile leather.
