Description

The Seiko SPB529J blends classic design with modern watchmaking craftsmanship, powered by the reliable Calibre 6R55 automatic movement. This mechanical timepiece is driven purely by the motion of the wearer, offering a robust 72-hour power reserve and accuracy of +25 to -15 seconds per day under normal conditions. Its clean analogue display features three hands and a date window, embodying Seiko’s dedication to precision and everyday functionality without reliance on batteries.

Encased in polished stainless steel, the SPB529J measures 40.2mm in diameter and 13mm in thickness—balanced proportions that offer both elegance and comfort. The grey dial, viewed through a dual curved sapphire crystal with anti-reflective coating, gives the watch a refined and understated charm. Completing the look is a silver upcycled leather strap that ties sustainability with style, reflecting Seiko’s growing commitment to environmentally conscious craftsmanship. The exhibition case back offers a glimpse into the intricate mechanics of the 6R55 movement, celebrating the beauty of traditional horology.

Built for both durability and sophistication, the SPB529J is water-resistant to 100 metres and includes a hand-winding capability for added control. As a limited edition of 3,000 pieces worldwide, it stands as a collector’s piece that harmonizes Seiko’s mechanical heritage with a modern design ethos. This model exemplifies Seiko’s ability to balance timeless aesthetics, sustainability, and mechanical innovation in a single, beautifully executed watch.
