Patek Philippe Nautilus 3900

Patek Philippe Patek Philippe Nautilus (Reference 3900). A stainless steel wristwatch with date, circa 1986

Description The Patek Philippe Nautilus Reference 3900, introduced in the mid-1980s, is a distinctive model within the Nautilus line. Designed as a versatile unisex watch, it features a 32.5mm case, earning it the nickname "mid-size" or "boy size" Nautilus. This model was produced between 1984 and 1995 in limited quantities, which has contributed to its growing appeal among collectors. During the 1980s, quartz technology was gaining popularity, and the reference 3900 is powered by Patek Philippe's Caliber E23 SC quartz movement, reflecting the brand's adaptation to market trends.  We are pleased to offer this watch accompanied by an Extract from the Archives confirming its year of manufacture in 1986 and subsequent date of sale in 1987.
