The Aquanaut, together with the Nautilus, are the sportiest from the independent manufacture house Patek Philippe. Not directly designed by Gerald Genta, it draws a great influence from the Nautilus (which was designed by Genta), from which it copies the shape of its dial and bezel. The reference 5167 was first presented in 2007, and was the update of the original model, and raises the size of the case to 40 mm. It is an extremely comfortable and elegant watch, even more so with the steel bracelet. The watch is in an exceptional condition, barely worn, dated 2010 and it is offered full set.
