The Seiko 5 Sports SSK001 is an automatic GMT watch launched in 2022. It pairs a case design inspired by the SKX with Seiko's Caliber 4R34 movement. A red GMT hand tracks a second time zone on the bi-directional 24-hour bezel, and a second 24-hour scale on the chapter ring tracks a third.
The Caliber 4R34 is a 24-jewel automatic movement that beats at 21,600 vibrations per hour. It has about 41 hours of power reserve, manual winding and hacking seconds. The GMT hand adjusts independently of the hour hand. To set it, pull the crown to the first position and turn it clockwise.
The black sunburst dial has applied indices with polished surrounds and a magnified date window at 3 o'clock. LumiBrite on the hands and markers helps legibility in low light. The 42.5mm stainless steel case is brushed with polished sides. It has undercut case sides, a crown at 4 o'clock and an exhibition caseback. The five-link stainless steel bracelet closes with a tri-fold push-button clasp with safety lock.
