In 1972, amidst an era marked by the quartz crisis, which saw the watch industry grappling with the influx of affordable quartz timepieces from Asia, Audemars Piguet launched the ‘Royal Oak,’ revolutionizing the market. Faced with the need to introduce a groundbreaking product, the company commissioned Gerald Genta to design a luxury sports watch made from solid stainless steel, a bold move at the time. Drawing inspiration from the robust aesthetics of deep-sea diving helmets, Genta conceived an iconic design featuring an octagonal bezel secured by visible screws, a substantial 39mm case seamlessly integrated with the bracelet, and a futuristic appearance that was avant-garde for the 1970s.

The introduction of the Royal Oak marked the creation of an entirely new category within the watchmaking industry, solidifying the appeal and prestige of stainless steel luxury sports watches. Within just two to three years of its release, approximately 1000 units were sold, a testament to its groundbreaking design and desirability. The inaugural model, the reference 5402, today known as the “Royal Oak A series,” incorporated the slender automatic calibre 2121 movement, a mechanism that continues to be produced to this day.

Audemars Piguet’s approach to treating steel with the same meticulous care as gold resulted in an exceptional level of finishing. This attention to detail set the Royal Oak apart, positioning it at a price point significantly higher than its contemporaries, including similar sports watches by Rolex, which were nearly ten times less expensive.

In the present day, Audemars Piguet continues to expand the Royal Oak collection, offering a variety of sizes ranging from 33mm to 41mm, catering to both women and men. These timepieces are available in an array of materials including titanium, rose gold, yellow gold, and platinum. Additionally, the collection features a diverse selection of dial colors and various complications, ensuring there is a Royal Oak to suit every taste.

Among the collection stands the exceptionally rare and highly coveted extra-thin Royal Oak, a special edition crafted exclusively for the Singaporean retailer “Hour Glass.” This model, reference 15205BA.OO.1240BA.01, is distinguished by its striking 39mm yellow gold case and exquisite green “Grande Tapisserie” pattern dial. Limited to just 50 pieces, this exclusive edition exemplifies luxury and exclusivity, capturing the essence of innovation and craftsmanship that defines the Royal Oak legacy.



Audemars Piguet – bio

Audemars Piguet is a Swiss manufacturer of mechanical watches founded in 1875. They began in the Vallée de Joux. Jules Louis Audemars formed a partnership with Edward Auguste Piguet. Audemars created complicated blank watch movements for other manufactures to use. Piguet specialized in the final regulation of watches. They then split responsibilities when they began their own company. Audemars was in charge of production and technical aspects while Piguet focused on sales and management. One of their first achievements was creating the first repeater wristwatch in 1892 and in 1972 the iconic steel “Royal Oak”.
