Seiko Presage Classic Series SPB445 Craftsmanship Arita Porcelain Dial

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.

The Seiko Presage SPB445 is a Classic Series “Craftsmanship” watch featuring a Hakuji Arita Porcelain dial. Seiko uses a transparent glaze to highlight the pure white colour of the porcelain, while simple bar indexes allow the porcelain's lustre to remain the focus. The outer portion of the dial features a delicate pattern, and the recessed sub-dial at 6 o'clock creates additional shading.

The 40.6mm stainless steel case is paired with a multi-row bracelet with contrasting finishes and a dual-curved sapphire crystal. Seiko also highlights the bent tips of the minute and seconds hands, which bring them closer to the dial markers for heightened legibility. The watch is powered by Calibre 6R5H with approximately 72 hours of power reserve.
