Seiko Watch - Seiko 5 GMT - SSK059

For the first time, the Seiko 5 Sports Field series introduces a new watch with GMT function. This watch is powered by the Seiko 4R34 movement, which hand winds and hacks, and provides a second independent time zone in 24 hour format. The GMT hand is stylish with a 5 sided arrow-head, done in red to contrast against the black dial.

Powered by the reliable Calibre 4R34 automatic movement, this watch offers both self-winding and manual winding capabilities, along with a 41-hour power reserve and 24 jewels for smooth, consistent performance. A dedicated 24-hour hand enables dual time tracking, while the stop-seconds function allows for precise time setting. The stainless steel case measures a versatile 39.4mm in diameter with a 13.6mm thickness and 47.9mm lug-to-lug, paired with a curved Hardlex crystal for added durability. LumiBrite on the hands and indices ensures strong visibility in low light, and the watch is secured with a three-fold clasp featuring a push-button release and secure lock. Additional features include a see-through screw case back, 100 meters of water resistance, magnetic resistance up to 4,800 A/m, and a total weight of 147 grams—making it a robust and practical choice for everyday wear.
