About this timepiece
Classic black and ready to cross time zones, the Seiko 5 Sports SKX Sports Style GMT (ref. SSK001) is a proud travel companion whose case and dial take their inspiration from the SKX series, one of Seiko's most-loved sports watches. A bright red GMT hand stands out sharply on the black dial, while the black and gray 24-hour bezel rotates and uses its two colors to split daytime from nighttime hours at a glance. A generous coat of LumiBrite on the hands, indexes and GMT hand keeps a second time zone as easy to read as local time once the lights go down.
Seiko's caliber 4R34 automatic GMT movement beats at 21,600 vibrations per hour with 24 jewels and offers approximately 41 hours of power reserve, with the option to wind it by hand. A Hardlex crystal with a magnifier over the date protects the dial, the bezel's ring indicator is also made of Hardlex, and the screw-down see-through case back shows the movement while helping deliver 100 meters of water resistance. The five-row stainless steel bracelet contrasts polished middle rows with solid outer links and fastens with a three-fold clasp with secure lock and push-button release.

Timepiece History
Seiko's story began in 1881, when a 21-year-old entrepreneur, Kintaro Hattori, opened a shop selling and repairing watches and clocks in central Tokyo. The first watch to carry the Seiko name followed in 1924, and Seiko went on to introduce a long line of watchmaking firsts, including the Quartz Astron, the world's first quartz wristwatch, on December 25, 1969. In 2024, Seiko celebrated the 100th anniversary of the Seiko brand.
The SSK001 belongs to Seiko 5 Sports, a collection rooted in the Seiko Sportsmatic 5 of 1963, Japan's first automatic day-date watch. Seiko 5 Sports itself was born in 1968, adding enhanced water resistance, a strengthened crystal and luminous hands and markers to the Seiko 5 essentials of an automatic movement, a day-date display, water resistance, a recessed crown and a durable case and bracelet, and it found worldwide favor as a go-anywhere watch. In 2019, Seiko 5 Sports was rebranded to carry watch culture forward to the next generation. Its design follows the SKX series, the successor to the watch widely known as the "SKX," a watch loved around the world. Seiko later added a GMT function to Seiko 5 Sports for international travelers, and with the rotating bezel it is possible to track three time zones. The SSK001 comes from the debut Seiko 5 Sports series to feature a GMT function, introduced with black, blue and orange dials.

Care Instructions
Daily Care
• Wipe the case and bracelet with a soft microfiber cloth after wear to remove oils, dust, and fingerprints.
Cleaning
• Use a soft cloth lightly dampened with water and mild soap for occasional cleaning.
• Dry the watch thoroughly with a clean, soft cloth.
What to Avoid
• Avoid bleach, chlorine, harsh chemicals, abrasive cleaners, and household cleaning products.
• Do not use polishing compounds unless specifically recommended by the watch manufacturer.
Stainless Steel and Titanium
• Light surface marks may develop over time with normal wear.
• Titanium can show cosmetic marks differently than stainless steel because of its lighter weight and surface characteristics.
Water Resistance
• Always follow the water resistance rating listed by the manufacturer for your specific watch.
• Water resistance is not permanent and can decrease over time as seals and gaskets age.
• Make sure the crown is fully pushed in or screwed down before water exposure.
• Do not operate the crown, pushers, or other controls while the watch is underwater unless the manufacturer specifically states that it is safe to do so.
• Avoid hot tubs, saunas, and very hot showers, as heat and rapid temperature changes can affect the watch seals.
• Have the water resistance checked periodically, especially after battery replacement, case opening, or service.
Storage
• Store your watch in a clean, dry place when not in use.
• Keep it separated from other jewelry or watches to help prevent scratches.
