Created to celebrate 145 years since Seiko began as a Tokyo watch and clock repairer in 1881, the King Seiko SJE121 Limited Edition revisits one of the brand’s most respected achievements, and is limited to 800 pieces. Inspired by the 1969 King Seiko 45KS, Japan’s first certified chronometer, this two tone redux reflects a pursuit of precision that defined an era. Beneath box shaped sapphire crystal, the grey Nanako stamped dial has a finely textured presence, catching the light softly while gold-coloured details add warmth and contrast. The distinctive arrow feather index at 12 o’clock brings a subtle sense of direction and intent.
Slim at just 9.9mm, the curved case and narrow link bracelet sit close to the wrist, feeling balanced and refined throughout the day. Powered by Seiko’s in house 6L35 automatic calibre, the SJE121 offers a 45 hour power reserve and reliable daily accuracy. This is a watch for those who value measured design, historic significance and the quiet pleasure of finely executed mechanical watchmaking.
• Powered by the 6L35 automatic movement with a power reserve of up to 72 hours.
• Presented on a silver stainless steel bracelet with push button deployment clasp.
• Scratch resistant sapphire crystal glass.
• 39.0mm case width.
• 50 metre water resistance.
