The Royal Oak Perpetual Calendar Openworked  Cactus Jack  Limited Edition, restricted to 200 pieces, makes a bold statement with its pioneering brown ceramic case, a first for Audemars Piguet. This 41 mm watch showcases a sapphire dial with smoked external zones around the counters and brown applied hour-markers. The movement’s components are accentuated with distinctive green and blue luminescent coatings. The timepiece is complemented by a brown calfskin strap and a special pink gold folding clasp, embodying both innovative design and exclusivity.
