KINGSEIKO 5626-8001, believed to have been manufactured in February 1975. This is a manual-winding and automatic watch.
This model features a design typical of the 56KS and a screw-down case back.
As shown in the photos, the case is in excellent condition with no noticeable scratches. There are some scratches on the crystal, but the dial is in excellent condition with no discolouration.
While many 56 series watches no longer have the ability to fast-forward the date, this one can fast-forward the date and day of the week by pulling the crown out one notch.
The size, measured by an amateur, is 36.1mm wide (excluding the crown), 18mm lug width, and 10.0mm thick.
The included watch is the genuine Seiko stainless steel strap shown in the photo, believed to be from the time of release. It measures an unusually long wrist circumference of approximately 19cm at its maximum.
