Released in the early 1970s, this model captures the golden age of Seiko’s tool watch innovation, combining form and function through its bold cushion case, vibrant red-and-blue 24-hour inner bezel, and dual-time GMT capability. Powered by Seiko’s in-house Cal. 6117 automatic movement with a quickset date and independently adjustable 24-hour hand, it remains a robust and reliable traveler’s companion. The case is unpolished and retains its original lines, paired with the correct Seiko bracelet.
