Seiko 5 Sports SKX GMT - SSK005

Bold, practical and built for travel, the Seiko 5 Sports SKX Sports Style GMT (ref. SSK005) brings a vivid orange dial and a bold black GMT hand to the much-loved SKX design. Its case and dial take their cue from the SKX series, and the two-color rotating 24-hour bezel separates day and night hours at a glance. Generous LumiBrite on the hands, indexes and GMT hand keeps everything legible in low light.

Seiko's caliber 4R34 automatic GMT movement beats at 21,600 vibrations per hour with 24 jewels and approximately 41 hours of power reserve, and it can be wound by hand. A Hardlex crystal with a magnified date window protects the dial, and the screw-down see-through case back reveals the movement while helping deliver 100 meters of water resistance. The five-row stainless steel bracelet, inspired by the original SKX design with polished middle rows, closes with a three-fold clasp with secure lock and push-button release.

Features

  • Caliber 4R34 automatic GMT – a 24-hour hand tracks a second time zone; approximately 41 hours of power reserve.
  • Two-color 24-hour bezel – a rotating bezel that separates day and night hours.
  • Magnified date window – Hardlex crystal with a magnifier for easy date reading.
  • LumiBrite throughout – on the hands, indexes and large GMT hand.

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 SSK005 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. It is part of the first series of Seiko 5 Sports watches with a GMT function.
