Description
The Seiko 5 Sports SKX SSK003K1 is a stylish and reliable timepiece built for everyday wear and travel. Powered by the Caliber 4R34 automatic movement with manual winding, it offers a 41‑hour power reserve, 24 jewels, and a dual time display with a 24‑hour hand.
Its stainless steel case is durable yet comfortable, measuring 7.6 mm thick, 30 mm in diameter, and 36.3 mm lug‑to‑lug, paired with a Hardlex crystal and a three‑fold clasp with push‑button release. At 161 g, it feels substantial without being heavy, and the 22 mm lug width allows easy strap changes.
Practical features include Lumibrite hands and indexes for night visibility, a rotating 24‑hour bezel, and a see‑through screw case back that reveals the movement. With magnetic resistance up to 4,800 A/m, the SKX SSK003K1 is built to perform reliably in modern environments.
