Rare and increasingly desirable Audemars Piguet “Cobra” ref. 5403BA in impressive condition with the golden dial with diamond indexes ! It is no coincidence that the Cobra features a ref. Number only one number away from the holy grail of the brand ref. 5402 Royal Oak.. both are early to mid 1970’s classics sharing an idea as well as the movement.. though this being the artsy sibling with soft curves and beautifully finished angles unlike the industrial Royal oak! This model is in beautiful condition and appears to be unpolished with a very tight bracelet good for wrists up to 18,5ish centimetres. The dial is perfectly preserved and has no patina or discoloration as we often see it on those models..!
