Aquanaut Travel Time 5650 Advanced Research

The 2017 Aquanaut Travel Time is the fourth watch in Patek Philippe's Advanced Research series, which serves as a showcase for the brand's most high-tech and cutting-edge technology. Housed in a Aquanaut case, the present watch features a high tech escapement as well as a novel mechanism to set the second time zone. It is sad to be adjusted to a mean rate of -1 to +2 seconds per 24 hours, which matches the rate accuracy of a Patek Philippe movement with a tourbillon.
