Patek Philippe Nautilus – Two-Tone Black Dial
📄 Brief of the Watch
The Patek Philippe Nautilus, Ref. 3800/1JA, is a classic reference representing the first "mid-size" or intermediate evolution of the original Genta design (Ref. 3700). This model is a striking Two-Tone blend of Stainless Steel and vibrant 18k Yellow Gold (used on the bezel, crown, and centerbracelet links). It features the iconic porthole-inspired case in a slightly more versatile 37.5mm size and the characteristic Black Gradient Dial with horizontal embossing. Powered by the reliable Calibre 330 SC movement, this reference offers a vintage aesthetic and is highly valued for its historical significance and rarity in this mid-size, two-tone configuration.
