Seiko Presage Classic Series ‘Sumi-iro’ Open Heart Watch

The Seiko Presage Classic Series ‘Sumi-iro’ Open Heart Watch combines Japanese elegance with timeless style. Designed with an eye for detail and inspired by traditional Japanese aesthetics, this timepiece embodies both sophistication and comfort, seamlessly blending heritage with modernity.

‘Sumi-iro’ Ink Black Dial, Case & Bracelet

Firstly, the dial of the Seiko Presage Open Heart is in an ink black shade known as ‘Sumi-iro’ (view white dial version here). The dial takes inspiration from the delicate texture of Japanese silk, a precious material in Japan’s history. Its texture, reminiscent of silk’s fine weave, creates visual depth. Secondly, the recessed ‘open-heart’ feature at 9 o’clock, shows the inner beauty of the movement within which powers the watch. Also, it features a recessed 24-hour subdial at 6 o’clock.

Protected by a dual-curved sapphire crystal with an anti-reflective coating, the curved dial features elegant curved hands and indices that capture and reflect light. This adds a vintage appeal. Additionally, the seven-piece, multi-row bracelet is designed with a nod to 1970s retro style, with each 6mm link adding flexibility and providing a comfortable, natural fit on the wrist.

Automatic Movement

Inside, the watch is powered by Seiko’s in-house 6R5J calibre, offering precise timekeeping. This automatic movement provides accuracy within a range of -15 to +25 seconds per day and delivers a robust 72-hour power reserve, so you can rely on its performance without needing frequent adjustments.
