Starting from the Eighties, Rolex introduced a series of stone dials not listed in their catalogues. The materials were very fragile therefore the manufacturing process was truly complicated. However, the purpose was to render this collection ever more exclusive, granting the owners of these timepieces a privileged feeling impossible to duplicate or copy.This outstanding 18208 reference manufactured in 1999, with smooth bezel exhibits a magnificent black Ammonite dial which features day and date apertures, diamond hour indexes and the coronet logo.The timepiece shows an overall "as new" condition characterised by unpolished sharp bevels, warming the heart of any watch collector. Moreover, the original Japanese warranty paper further underscores the added value of this piece.
