Seiko 5 Sports SSK003K1

The Seiko 5 Sports SSK003K1 Navy reinterprets one of Seiko's most beloved sports watches, drawing its case and dial design directly from the legendary SKX series that generations of enthusiasts have collected for decades. A deep navy blue dial pairs with a bi color rotating bezel that separates day and night hours at a glance, while a newly developed 4R34 mechanical caliber adds genuine GMT functionality, letting wearers track two time zones simultaneously through a dedicated 24 hour hand. Bright red GMT hand detailing ensures clear legibility against the blue dial, while a generous application of Lumibrite across the hands and indexes keeps the watch readable in low light conditions. The five row stainless steel bracelet introduces a genuinely new design still rooted in the original SKX aesthetic, with polished center links contrasting against the more solid outer rows for real visual depth. Reinforced water resistance rated to 10 ATM makes the watch suitable for daily wear and recreational swimming alike, while a screw down see through caseback reveals the automatic movement in action. Backed by up to 41 hours of power reserve on a full wind, this Navy colorway offers collectors a genuinely functional, heritage rooted GMT watch within Seiko's celebrated 5 Sports lineup. The Seiko 5 Sports SSK003K1 Navy carries a retail price of $495.
