The Patek Philippe Nautilus 3800/1JA is the second and mid-size version of this iconic Patek Philippe model. Introduced as a more compact alternative to the original 3700, this reference features a 37.5 mm case in a rare two-tone combination of stainless steel and 18k yellow gold, offering a perfect balance between sportiness and sophistication.

Signature of the Nautilus is the rounded octagonal bezel with the protruding ears and horizontally ribbed dial. Powered by the ultra-thin Caliber 335 SC automatic movement, it delivers exceptional precision while maintaining a slim profile. The integrated two-tone bracelet ensures a seamless, comfortable fit on the wrist.
