The Royal Oak is one of the most important watches in the history of watchmaking. Gerald Genta's genius is fully expressed in this 36mm "mini-jumbo" version, which is often easier to wear because of its smaller size compared to the famous 39mm "Jumbo". However, the mini-jumbo has nothing to envy the jumbo, AP having done an excellent job of adapting the proportions and appearance that make up the very soul of the Royal Oak. 
The SA version, meaning that the watch combines two materials, yellow gold and steel, is probably one of the most beautiful two-tone watches ever produced (if not the most beautiful). It fully highlights the characteristic angles and revolutionary style of this timeless model, while giving it a very warm visual and wearing appeal thanks to the gold. 
This specific example has a mk1 dial, recognizable by the fact that the "Audemars Piguet" lettering is completely written in capital letters. The case, bracelet and dial are in fantastic condition. The latter is truly immaculate, with no signs of scratches or oxidation. Rarely seen on these references, and even more so on a mk1, the watch comes with its original box and papers, making it a true collector's item.
