Patek Philippe Nautilus: Overview

The Nautilus by Patek Philippe represents the pinnacle of watchmaking. In-house calibers create a timepiece meant to outlast generations.

The Patek Philippe Nautilus is frequently counterfeited. Here is how to verify authenticity:

Hallmark: serial engraving must be present and professionally executed. Thin plating on fakes wears quickly.

Stones: Authentic Nautilus uses quality stones with precise setting. Check for gaps in the bezel setting.

Weight: Authentic pieces have substantial feel. Unusually light weight suggests gold plating.

Store in the original box when not wearing. Apply perfume and lotions first to preserve gold luster and stone brilliance.

Clean monthly using a soft brush and mild soap and water. Avoid ultrasonic cleaners as they may damage delicate stones.

Have prongs and settings checked annually to prevent stone loss. Proper storage will keep your Nautilus sparkling for decades.
