Rare and very desired configuration. Rarely did Mark I dials turn cark and even less with such an even patina. A piece with a lot of travelling history. Original and mint dial and matching original hands. Original fat font ghost faded black bezel. Professionally polished case returning its original beveled edges. Very clean serial # (1,952,XXX). Equipped with a newer high quality leather strap and Rolex stainless steel tang buckle.
