SEIKO 5 Watches Mod. SSK003K1 – 5 Sports GMT “Blueberry” Automatic Watch

Product Description

The SEIKO 5 Sports SSK003K1, often nicknamed the “Blueberry GMT”, is one of the most popular watches in the Seiko 5 Sports collection. Inspired by the legendary SKX dive-watch design, this model combines sporty aesthetics, automatic movement technology, and practical GMT functionality for tracking a second time zone.  

Powered by Seiko’s reliable Calibre 4R34 automatic movement, the watch offers both automatic and manual winding capability, a GMT hand for dual-time display, a stop-seconds function, and approximately 41 hours of power reserve.  

The striking sunray blue dial is paired with a distinctive black and blue 24-hour rotating bezel, giving the watch its famous “Blueberry” nickname. Large LumiBrite-coated hands and indices provide excellent readability in low-light conditions.  

Its robust 42.5mm stainless steel case is fitted with a durable Hardlex crystal and a transparent case back that showcases the automatic movement. With 100m (10 bar) water resistance, the watch is suitable for everyday wear, swimming, travel, and outdoor adventures.  

The five-row Jubilee-style stainless steel bracelet enhances comfort while maintaining the vintage SKX-inspired aesthetic that collectors and enthusiasts love.
