SEIKO PRESAGE CLASSIC SERIES AI-IRO OPEN HEART AUTOMATIC WATCH – 40.2MM INDIGO BLUE DIAL STEEL BRACELET

'Ai-iro' — the colour of indigo — has been part of Japanese textile culture for centuries, associated with samurai warriors and the deep blues of traditional Japanese craft. The SPB527J1 brings that colour to the Presage Classic Open Heart, rendering it in a silk-textured dial that shifts tone under different light. The 6R5J calibre is visible through the open-heart aperture at 9 o'clock, and a 24-hour subdial adds a second complication at 6 o'clock.

Why This Watch Stands Out

• Ai-iro indigo blue dial inspired by traditional Japanese samurai culture — deeply significant and beautiful
• Open heart aperture at 9 o'clock — the movement beats visibly as part of the dial composition
• Seiko Calibre 6R5J automatic — 72-hour power reserve, hand-winding and hacking
• Silk-textured dial surface that catches light differently across the day
• 40.2mm case with dual-curved sapphire crystal for a classic, refined dress-watch profile
