Seiko Presage Classic Series Automatic 40.6 MM Steel Blue Dial Watch SPB445J1

This creation features a “Hakuji” dial that highlights the pure white color of the porcelain material through an application of transparent glaze. Simple bar indexes have been used so as not to detract from the porcelain’s luster, a quality enhanced by the curved surface of the dial's outer circumference.
On the dial, which measures 31.6mm in diameter, the area just inside the indexes is decorated with a delicate pattern, and the sub-dial at the 6 o'clock position is recessed to achieve delicate shading.

The case design is at once graceful and sharp. Secured by a multi-row bracelet with links in contrasting finishes, the watch rests comfortably and securely on the wrist while enhancing the lustrous appearance of the Arita Porcelain dial.
The tips of the minute and seconds hands are bent toward the dial, bringing them closer to the dial’s markers for heightened legibility, and a dual-curved sapphire glass minimizes the thickness of the case. A super-hard coating enhances the case and bracelet while protecting the watch from scratches.

Arita Porcelain Dial

See-through & Screw case back

This Arita porcelain dial is created through handwork and firing at a high temperature. As a result, it may have little dimples, tiny dots, and an uneven color. These are unique features of genuine Arita porcelain dials, of which no two are exactly alike.
