Seiko 5 Sports GMT SSK003 – “Blueberry” Automatic GMT

The Seiko 5 Sports SSK003 combines the unmistakable styling of the legendary Seiko 5 Sports line with the added functionality of a mechanical GMT complication. Nicknamed the “Blueberry,” this model stands out with its rich blue sunburst dial and striking black-and-blue 24-hour GMT bezel.

Powered by Seiko’s Caliber 4R34 automatic movement, the SSK003 allows you to track a second time zone using its contrasting red GMT hand and 24-hour scale. The movement offers both automatic and manual winding, hacking seconds, and approximately 41 hours of power reserve. A transparent exhibition caseback provides a view of the mechanical movement.

The stainless-steel case is paired with Seiko’s comfortable five-row/Jubilee-style bracelet, giving the watch a classic sports-watch appearance with plenty of wrist presence. Large LumiBrite hands and hour markers provide excellent visibility, while the Hardlex crystal with magnified date window adds one of the SSK series’ most recognizable design touches.
