The Audemars Piguet Royal Oak Navy Blue Ballpoint Pen is an essential writing instrument for Royal Oak enthusiasts. Inspired by the iconic elements of the Royal Oak, the pen features an octagonal shape and is intricately engraved with a pattern resembling the legendary Tapisserie dial. Mirroring the craftsmanship of the timepiece, the pen showcases areas of brushed and high-polish finishes, with a sheen of silver-plated rhodium-coated metal. The twist-top cap and clip are elegantly engraved with “50 Royal Oak” and “Audemars Piguet,” celebrating 50 years of horological excellence. The Royal Oak pen uses Caran d’Ache refillable cartridges. Please note that the boxes may vary slightly depending on the year of production.
