Seiko 5 Sports GMT

Seiko has expanded its Seiko 5 Sports family by adding a new GMT series.

Introduced in 1968, Seiko 5 Sports series of mechanical watches has been renowned for their durability and reliability. In 2019, the collection was relaunched, by introducing new active and youthful watch models.

Now, for the first time, Seiko 5 Sports collection welcomes a new GMT series powered by the Caliber 4R34. Based on the tried and trusted platform of Caliber 4R, this new series offers the convenience of a GMT hand in a case that is just 0.1 mm thicker than the existing one.

Designed for the international traveler, the Seiko 5 Sports GMT watch is now available in three color ways: black, blue and orange.

To enhance readability, the GMT hands and bezels use different colors. For example, the GMT hands are in bright red on the black and blue dial versions and in black for the version in orange.

Just like the time of day hands and indexes, the GMT hand has a generous layer of Lumibrite to ensure legibility in low light conditions. The two-toned rotating bezel allows the user to quickly differentiate the night and day hours.

The bezel-insert is made of Seiko’s Hardlex glass to deliver the high level of durability for which the Seiko 5 Sports collection is renowned.

The design of the case and dial draws inspiration from one of Seiko’s best-loved sports watches, known to enthusiasts as the Seiko SKX series. The five-row bracelet is a new design also inspired by the original SKX series in which the middle rows are polished to create a contrast with the solid feel of the rows that bind them.

All the three Seiko 5 Sports GMT watches will be available at selected Seiko Boutiques and other retail stores worldwide in July 2022.
