Seiko 5 Sports SSK003 Automatic GMT – Blue Dial – Stainless Steel
 
Sporty automatic travel watch with dual-time tracking, a blue-and-black 24-hour bezel and classic five-row bracelet
This Seiko 5 Sports SSK003 combines the familiar SKX-inspired case design with an automatic GMT movement capable of displaying a second time zone. It features a deep blue dial, contrasting red GMT hand, luminous markers and a black-and-blue rotating 24-hour bezel. The stainless steel construction, exhibition caseback and practical 100-metre factory water-resistance rating make it suitable for travel, daily wear and casual sport use.
 
Condition:
Excellent pre-owned condition overall. The Hardlex crystal and date magnifier are clean with no visible scratches, cracks or chips. The case, bezel, dial, and hands are exceptionally clean, while the stainless steel bracelet has only very minor surface scratches from normal wear.
Fully tested with no known functional or mechanical issues. The automatic movement runs properly, keeps time, and the date and GMT functions operate correctly.
Two bracelet links are missing, so the bracelet currently fits wrists up to approximately 7 inches. Additional compatible links would be required for a larger wrist.
