Here we have a beautifully designed Audemars Piguet Royal Oak but despite the bracelet and design language similarities, AP never called the 6009BA a Royal Oak, it went simply by the ‘Quartz Line’. 

Our particular Reference 6009 BA comes in a 28mm 18k solid yellow gold case with an unsigned crown and a yellow gold colored typical Royal Oak tapisserie dial with a yellow gold 'stick' handset. These version is for all those who prefer rectangular case shapes before the octagon shaped classic Royal Oak.
