From our About page

Limited edition Seiko 5 Sports GMT SSK043K1 featuring Seiko Caliber 4R34 automatic movement with approximately 41-hour power reserve, GMT function, 100m water resistance, and a Hardlex crystal. Limited to 1,300 pieces and exclusive to select Asian markets.

The Seiko 5 Sports GMT SSK043K1 “The Slam Dunk of Style” is a unique limited-edition timepiece inspired by the dynamic energy of basketball and exclusive to the Thong Sia Group (Malaysia, Brunei, Hong Kong, Macau, and Singapore). Limited to 1,300 pieces, this model blends everyday versatility with specialized features for frequent travelers and watch enthusiasts.

At its core is Seiko’s Caliber 4R34 automatic movement, a robust and reliable engine with manual winding capability and an approximate 41-hour power reserve. The GMT complication tracks a second time zone, making the watch functional for global lifestyles while preserving the classic Seiko 5 Sports ethos of durability and practicality.

The watch features a 42.5 mm stainless steel case with a unidirectional rotating bezel, finished with a Hardlex crystal and a comfortable stainless steel bracelet. The dial and overall design draw inspiration from the theme of dynamic motion and bold style. Lumibrite on hands and indices ensures excellent visibility in varied conditions, and the screw case back, marked with its serial number, highlights its limited edition status.

With 100 m water resistance, this GMT is suitable for everyday wear and aquatic activities, combining sportiness with collectible appeal.
