The \u2018Royal Oak\u2019 overturned the prevailing codes in 1972 during a period of existential crisis for the watch industry due to the boom of the cheap Quartz watches made in Asia.
\nThe company had to come with a bold, solid stainless sports steel luxury watch, they gave the mission to Gerald Genta to design it.
\nHe got the inspiration from a deep-sea-diving helmet, the result was an octagonal bezel, visible mounting screws, a large case of 39mm with an integrated bracelet, a very futuristic design for the seventies.
\n<\/span>Within 2-3 years they sold about 1000 watches establishing a new segment within the industry and pioneered the popularity and desirability of the steel sports luxury watch.
\nThe first model released was the reference 5402 known today as the \u201cRoyal Oak A series\u201d, with a thin automatic calibre 2121 movement that is still made today.
\n<\/span>Since they treated steel as gold, the level of finishing was remarkable and so was the retail price, for comparison purpose a similar Rolex sport watch was 10x cheaper.
\nToday, Audemars Piguet still produces a range of Royal Oaks in different sizes (33 to 41mm) for ladies and men, from titanium, rose gold, yellow gold and platinum metals, various dial colours and with different complications.<\/p>\n


\n*<\/strong>Following the success of the \u201cJumbo\u201d steel Royal Oak, Audemars Piguet introduced in 1977 the very first 18k yellow gold version under reference 5402BA<\/strong>, production of these models lasted until the early 1980s.<\/p>\n

While the first 5402 steel models were divided into four alpha-numerical series from A to D, the yellow gold as well as the two-toned models were first launched in the late 1970s and were numbered simply from 1 (coincidently the very coveted number \u201c1\u201d serial in two-tone<\/a> is available with us) the current model has its serial in the late 400s therefore in the batches of Royal Oak Jumbos made in 1979 as it has been confirmed by the factory.<\/p>\n

This famous sporty chic models has its iconic case and octogonal bezel in excellent condition, the grey dial with “Tapisserie” pattern features a date at 3 o’clock, central gold hands with luminescent coating, gold hour markers with luminescent coating as well and the “AP” logo and inscription at 12 o’clock.
\nThe inscription “Automatic” at 6 o’clock on the dial refers to the self-winding calibre 2121 beating under this dial and protected by the solid yellow gold case-back also featuring an inscription : “Royal Oak”<\/p>\n

Audemars Piguet – bio<\/strong><\/p>\n

Audemars Piguet is a Swiss manufacturer of mechanical watches founded in 1875. They began in the Vall\u00e9e 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 \u201cRoyal Oak\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
