Three innovations. One watch. The 5650G Advanced Research takes the Aquanaut Travel Time and transforms it into a showcase of next-generation mechanical engineering — a compliant GMT mechanism with no traditional moving parts, an optimised Spiromax hairspring, and a semi-openworked dial revealing it all. Fifth in the Advanced Research lineage, limited to 500 pieces, and widely regarded as one of the most technically important modern Patek Philippe references ever made. Unworn condition. Complete full set from 2017. This is what the cutting edge looks like.
