Inspired by the traditional color Ai iro

The dial draws on the historic indigo color Ai iro, which has been cherished in Japan for centuries. During the Samurai era, it was considered a lucky color and later became known internationally as “Japan Blue.”

The intense blue hue gives the watch a special depth and ensures an elegant, timeless appearance.

Open heart as an expression of mechanical watchmaking art

The opening in the dial allows a view of the oscillating balance wheel of the automatic movement. This so-called open heart makes the mechanics visible and gives the watch an exceptional character.

The interplay of classic design and visible technology makes the SPB527J1 a standout highlight within the Presage collection.

Inside works the powerful Seiko Caliber 6R5J, offering a power reserve of up to 72 hours. Additionally, the movement features a hacking seconds function, manual winding capability, and a practical 24-hour display.

This combination ensures high everyday usability and reliable precision.

High-quality craftsmanship for every occasion

The balanced proportions and careful finishing give the watch an elegant presence on the wrist. With water resistance up to 10 bar, the SPB527J1 is suitable for both everyday wear and special occasions.
