There was a time when watchmakers would take their most popular models and rework them into uncommon shapes and sizes. This amazing and funky Royal Oak hybrid is the perfect example.

The Gerald Genta-designed Royal Oak is one of the most iconic watch designs. Its octagonal case and integrated bracelet have inspired countless designs from other brands. Yet, Audemars Piguet has produced some interesting Royal Oak branded spin offs as well.

This lovely ref. 6005BA takes the Royal Oak’s timeless octagonal shape and stretches it into a rectangular variety. The watch dates back to 1979 and features an 18k yellow gold ‘hinged’ case with a matching gold bezel complemented by Genta’s famous integrated Royal Oak bracelet. This ‘Jumbo’ variant measures 32 x 41 mm.

The 6005 is powered by Audemars Piguet’s caliber 2511, a unique quartz movement with an ingenious mechanism to set the time. The minute hand can be adjusted by pressing down on a hidden button in the center of the crown with a wooden toothpick. When the button is engaged, the minute hand sweeps forward until the button is released when the hand reaches the correct position. The hour hand can then be adjusted by pulling out the crown and twisting it to the approximate hour position. When the crown is pushed back in, the hour hand automatically jumps to the accurate position relative to the minute hand!

This rare and creative Royal Oak variant is in excellent condition, having just returned from a full service at our trusted Audemars Piguet service center. The watch is accompanied by the corresponding service papers and an extract from the Audemars Piguet archives.
