The **Patek Philippe Nautilus 40th Anniversary Chronograph Ref. 5976/1G-001** is a celebration of one of the most important designs in modern watchmaking. Housed in an **oversized 44 mm case** (49.25 mm lug-to-lug), the watch is sculpted from solid **18k white gold**, featuring the signature Nautilus porthole-inspired construction and alternating polished and satin finishes.

The **sunburst blue dial** radiates from the center with a deep metallic sheen, adorned with **baguette-cut diamond hour markers** and the engraved anniversary logo:
“**1976–40–2016**.”
The balanced layout integrates a **monocounter chronograph sub-dial at 6 o’clock**, displaying both 60-minute and 12-hour totalizers.

Inside beats the **Patek Philippe Calibre CH 28-520 C**, an automatic flyback chronograph movement with a **column-wheel and vertical clutch** mechanism, ensuring seamless start-stop operation. Running at 4 Hz with a **55-hour power reserve**, it combines robustness with the finest Geneva craftsmanship. The sapphire crystal caseback reveals its impeccable finishing — Geneva stripes, circular graining, and the **Patek Philippe Seal** of excellence.

The integrated **white gold bracelet** perfectly complements the case with a secure **fold-over clasp**, ensuring both comfort and luxury. Water-resistant to **120 meters**, the 5976/1G represents not only a technical achievement but also a milestone in Patek Philippe’s heritage — a tribute to 40 years of the Nautilus, blending artistry, rarity, and history.
