Overview

The Patek Philippe Nautilus 40th Anniversary Ref. 5976/1G-001 was created to celebrate four decades of the Nautilus — an icon of modern horology. Crafted in solid 18K white gold and featuring a deep blue sunburst dial engraved with the commemorative “40” anniversary inscription, this limited edition of only 1,300 pieces is a symbol of exclusivity, heritage, and technical excellence.

Design & Materials

• Case: 44 mm (measured diagonally from 10 to 4 o’clock) 18K white gold case — larger and more commanding than the classic Nautilus, combining satin brushing and high polish for dramatic effect.
• Bezel: Rounded octagonal bezel in polished white gold, retaining the distinctive porthole-inspired design conceived by Gérald Genta in 1976.
• Dial: Gradient blue sunburst dial with horizontal embossed pattern, featuring applied white gold hour markers with baguette-cut diamond accents and the commemorative inscription:
  
  “1976 – 40 – 2016”.
• Bracelet: Integrated 18K white gold bracelet with polished center links and satin-brushed outer links, secured by a fold-over clasp.
• Aesthetic: Powerful, radiant, and symbolic — the deep blue dial and white gold case perfectly encapsulate 40 years of Nautilus legacy and prestige.
