Seiko 5 Sports SSK001

The Seiko 5 Sports SSK001 in Black is a GMT automatic watch from the Seiko 5 Sports SKX Sports Style GMT Series, marking the first time a GMT function appeared in the Seiko 5 Sports line and drawing its case design and five-row bracelet inspiration directly from the legendary Seiko SKX series that established Seiko's reputation as the most accessible route to a reliable mechanical diver-style watch. The SSK001 features a black dial with bold Lumibrite luminous hands and markers, a large red GMT hand for second time zone visibility in low light, a bi-color metalized rotating bezel with a Hardlex glass ring indicator where the color split separates night and day hours, a 42.5mm stainless steel case with screw-down see-through caseback, and the classic five-row stainless steel bracelet with polished middle rows contrasting the brushed outer rows, finished with a tri-fold push button release clasp. The movement is Seiko's 4R34 automatic caliber developed specifically for the SSK series, with 24 jewels, 21,600 vibrations per hour, approximately 41 hours power reserve, manual winding capability, and the GMT hand that completes one revolution per day in one-hour increments readable against the bi-color 24-hour bezel scale, providing genuine dual time zone functionality at a price point that established the SSK series as the most accessible automatic GMT watch in the global watch market upon release. Water resistance is rated to 100 meters, suitable for recreational swimming. At $495 retail the SSK001 is available through Seiko authorized dealers globally.
