Catalogue Essay
Audemars Piguet's introduction of the Royal Oak marked the beginning of the luxury sports watch market we know today. Launched in 1972 at Basel Fair, it caused an immediate sensation as the watch industry had never seen anything comparable before. It was at the time the most expensive steel wristwatch available. It most notably housed the extra slim caliber 2121 based on the Jaeger-LeCoultre cal. 920, that would later be found in the Nautilus wristwatch. Today, the Royal Oak remains as iconic as ever, with early examples being exceedingly popular and collectible.
Known as the "A Series", the present watch is the original Royal Oak model produced in the 1970s. According to Audemars Piguet Archives, the movement 127082 was originally fitted in case number 67038, Royal Oak A38. It was changed to the current case sometimes before year 2000.
Preserved in excellent condition, it displays thick bevels, crisp finishes and even its original Gay Frères bracelet stamped for 1972.
