Created to mark 145 years since Seiko’s origins as a Tokyo watch and clock repairer in 1881, the Seiko Astron SSH186 Limited Edition reflects both heritage and forward thinking design, and is limited to 1450 pieces. Part of a commemorative collection, this model draws inspiration from a solar eclipse, expressed through a deep black dial accented with warm gold tones that suggest light breaking through darkness. The super hard coated titanium case feels impressively light yet robust, its smooth surfaces and angular profile giving the watch a contemporary presence that sits neatly on the wrist beneath dual curve sapphire crystal.
Designed with comfort in mind, the low centre of gravity and integrated titanium bracelet create a balanced, almost seamless fit. Powered by Seiko’s in house 5X83 solar movement, the SSH186 offers GPS timekeeping, dual time display and a 1/20th of a second chronograph, all charged by light. The carefully arranged sub dials add technical interest without overwhelming the design, making this a refined choice for those who value precision engineering, modern materials and a quietly distinctive aesthetic.
• Powered by the 5X83 solar powered movement with a power reserve of up to 6 months.
• Presented on a black titanium bracelet with push button deployment clasp.
• Scratch resistant sapphire crystal glass.
• 44.0mm case width.
• 100 metre water resistance.
