Since its introduction the Explorer II reference 16550 with stepped 24-hour bezel and a large luminous arrow has certainly lived up to its name - it was part of the standard equipment of several highly challenging expeditions late in the 20th century, such as the GEOMAG North expedition.
The Explorer II models - particularly those with white dials from the three year pre-r series - have become favourites among collectors of Rolex sports watches. Due to a flaw in the colour used for the dials, they began to darken somewhat with time, many of them developing a striking patina; hues are ivory, pale beige or even cream such as this piece. Its Italian fans have lovingly named it the "panna dial".
