Royal Oak Offshore "Navy"

The Audemars Piguet Royal Oak Offshore Reference 26020ST.OO.D020IN.01—often nicknamed the “Navy” Offshore—is a bold 42 mm sports chronograph from 2000–2005 that beautifully balances ruggedness and refinement.

• Case & Bezel: Brushed stainless steel, octagonal bezel secured by eight hex screws; case measures about 42 mm in diameter and ~15 mm thick, water-resistant to ~100 m.
• Dial & Hands: White “Mega‑Tapisserie” waffle dial with contrasting navy blue subdials (chronograph from 12/9/6 o’clock), large Arabic numerals, and Royal Oak-style hands filled with luminescence.
• Strap & Crown: Navy leather or rubber strap (crocodile “horn‑back”), secured by a steel folding clasp; features a screw‑locked crown and rubber-clad chronograph pushers.
• Movement: Powered by AP’s automatic calibre 2226/2840 (some later noted calibre 3126/3840), offering ~40‑50 hr power reserve.
• Functions: Displays hours, minutes, small seconds, date (at 3 o’clock), chronograph, and tachymeter scale on the flange.

This reference is a signature Offshore iteration—combining the iconic Royal Oak DNA with oversized proportions, bold color contrast, and serious sports-watch engineering. It’s a standout for collectors drawn to the Offshore’s robust aesthetic and historical 2000s-era appeal.
