This is a steel Patek Philippe Nautilus Ref. 3800/001, featuring an extremely rare slate grey sunburst dial with white Arabic numerals. Sometimes referred to as a “telephone dial” due to its resemblance to the rotary dial of old telephones, it is considered the rarest dial variant of the Patek Nautilus.

Making it even more collectible, this piece comes accompanied by its Certificate of Origin, confirming the original “ardoise” (slate grey) dial and noting its 1987 year of production. It also comes with its PP product literature, leather holder, hang tag and box. This watch is self-winding, and the case measures 37.5mm wide.
