Patek Philippe Aquanaut 5650G, Advanced Research One of 500, White Gold

As the first of Patek Philippe’s ‘Advanced Research’ watches to innovate using a material other than silicon (forgoing the use of an annual or perpetual calendar complication), the reference 5650G represents something of a transition, introducing two innovations. Unlike earlier, classically-styled Advanced Research pieces from the series, both the open-worked dial and Aquanaut case of this 5650G, although polarising, match the ambitions of the reference - a limited-production of just 500 pieces, showcasing innovation in traditional watchmaking.
