Circa 1980, a desirable Porsche Design watch by IWC, structured with a double case and hidden compass and mirror. Featuring the moon phase indicator in cream yellow. IWC Cal. 37541 Movement, 22 jewels. Aluminum case measuring 39mm. With the original aluminum bracelet. The piece is in uncommonly nice condition, just with a small scratch to the bezel next to the four mark. Light on the wrist, with a timelessly cool design.
