Patek Philippe 3900 Nautilus 1989

The Patek Philippe Nautilus Ref. 3900 encapsulates the spirit of the iconic Nautilus line in a refined, mid-size format. Introduced in the early 1980s, this reference delivers the same distinctive porthole design and sporty elegance of its larger siblings, all while offering a slimmer, more understated wrist presence. For collectors and enthusiasts who value classic proportions and timeless design, the 3900 is a hidden gem.

Signature of the Nautilus is the rounded octagonal bezel with the protruding ears and horizontally ribbed dial. Powered by the ultra-thin Quartz Caliber 23 SC, it delivers exceptional precision while maintaining a slim profile. The integrated stainless steel bracelet ensures a seamless, comfortable fit on the wrist.

The best part of this particular piece that comes with the original Patek Philippe certificate from the first purchase in Lugano Switzerland from 2nd October 1989.
