Introduced at the end of the decade, this reference marks a turning point in the history of the collection as the first Royal Oak to feature a central seconds hand and a more seamlessly integrated automatic movement.<\/p>\n<p data-start=\"456\" data-end=\"998\">The case, crafted in 18-carat yellow gold, displays harmonious proportions with a 35 mm diameter and a slim profile, offering a subtle yet elegant presence on the wrist. The octagonal bezel with its eight hexagonal screws, the sharp edges, and the perfect continuity of the integrated bracelet recall Genta\u2019s original vision, here elevated by the warmth of precious metal. The alternation of polished and satin-brushed surfaces demonstrates the precision and craftsmanship that define Audemars Piguet\u2019s finishing excellence.<\/p>\n<p data-start=\"1000\" data-end=\"1415\">The \u201cPetite Tapisserie\u201d dial, a true signature of the Royal Oak, reveals a fine guilloch\u00e9 pattern that plays beautifully with the light. Its gold baton hour markers and matching hands ensure balanced readability, while the discreet date window at 3 o\u2019clock is seamlessly integrated. The dial\u2019s tones shift between soft champagne and brushed silver depending on the light, harmonizing perfectly with the warmth of the case.<\/p>\n<p data-start=\"1417\" data-end=\"1798\">Inside beats the automatic calibre 2123, derived from the legendary Jaeger-LeCoultre 920 movement, reworked and finely finished by Audemars Piguet. This ultra-thin calibre, featuring a central seconds hand and an openworked rotor, offers remarkable reliability and a level of technical refinement rare for its time. It played a key role in establishing the Royal Oak as a pioneering luxury sports watch.<\/p>\n<p data-start=\"1417\" data-end=\"1798\">The Royal Oak 4100BA in yellow gold occupies a special place in the history of Audemars Piguet. Rarer than its steel counterparts, it combines the strength of the original design with the nobility of precious metal. It appeals to discerning collectors who seek the very essence of the Royal Oak: a watch that is simultaneously sporty, architectural, and profoundly elegant. A creation where Genta\u2019s hand meets the glow of gold, a testament to an era when Audemars Piguet redefined the concept of luxury with boldness and mastery.<\/p>\n<p data-start=\"1800\" data-end=\"2107\">This 1979 example stands out for its excellent vintage condition: well-preserved case, sharp edges, complete original bracelet, and untouched dial with a soft, even patina. The ensemble reflects the perfect balance between the charm of a vintage timepiece and the technical precision of a great manufacture.<\/p>\n<p data-start=\"2109\" data-end=\"2471\">\n<\/div>\n<\/div>\n<\/div>\n<div class=\"flex justify-between lg:block\">\n<div class=\"text-gray-400 flex self-end lg:self-center justify-center mt-2 gap-2 md:gap-3 lg:gap-1 lg:absolute lg:top-0 lg:translate-x-full lg:right-0 lg:mt-0 lg:pl-2 visible\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p><strong>La Premi\u00e8re Royal Oak Interm\u00e9diaire<\/strong><\/p>\n<p>Royal Oak 4100SA, mesurant 35,5 mm de diam\u00e8tre, ce mod\u00e8le de taille interm\u00e9diaire conserve toutes les qualit\u00e9s de l&rsquo;iconique Jumbo, mais dans un format plus petit et surtout plus adapt\u00e9 \u00e0 son \u00e9poque.
