The Seiko SSK005 (Japan reference SSK005J1) is a Japan-made automatic GMT with a bright orange dial, dual-time capability, and 100 m water resistance. Powered by calibre 4R34, it pairs a 42.5 mm stainless steel sports case with a rotating 24-hour bezel so you can track a second time zone on the wrist.
This is the bold colourway in Seiko’s accessible GMT line: sunburst orange dial, gold-tone accents, LumiBrite hands and indices, and a five-row stainless bracelet. The “J1” suffix marks Japan production. It suits travellers, dual-timezone workdays, and anyone who wants a colourful Seiko 5 Sports GMT that still reads as a proper sports tool watch. In stock at Chronospride with Sydney dispatch.
Why the Seiko SSK005 / SSK005J1 stands out
- True GMT hand: independent 24-hour hand plus rotating 24-hour bezel for a second (or third) zone reference.
- Calibre 4R34: automatic GMT with manual-wind capability, 24 jewels, and about 41 hours power reserve.
- Sports case geometry: 42.5 mm diameter, about 13.6 mm thick, roughly 46 mm lug-to-lug; crown at 4 o’clock with guards in the familiar Seiko sports silhouette.
- 100 m water resistance: suitable for swimming and active daily wear (not scuba).
- Japan-made orange colourway: SSK005J1 is the vivid alternative to the black SSK001 on the same Seiko 5 Sports GMT platform.
