This 40mm Jumbo Aquanaut couldn't be better! UK retailed in February 2019, this solid steel Jumbo is in brand new, factory condition. Following in the footsteps of the Nautilus, these Aquanaut models have been some of the fastest appreciating sports watches of recent years and the waiting lists have become so long that the Patek Salons world-wide have even closed their books on them. Complete with its original Patek box, warranty certificate, booklets and tags, this 51671A/001 is under 2 year international warranty with Patek Philippe themselves.
