Description

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.

2017 Advanced Research execution of caliber 324 S C FUS; featuring a new Spiromax balance spring made of Silinvar; apart from the patented terminal curve (Patek Philippe boss at the outer end), its geometry now also features an inner boss near the integrated collet, and a ompliant (flexible) mechanism crafted from conventional horological steel that is used to set the second time zone in time-zone watches. . The new control mechanism for time-zone adjustments with flexible elements unites a number of advantages: simpler assembly (12 parts as opposed to 37), faster assembly (4 screws), flatter silhouette (1.24 mm versus 1.45 mm), no mechanical play, no friction, and no arbor wear, which assures completely lubricant-free functionality. On the other hand, these benefits impose greater requirements as regards conceptual complexity and production methods that call for more extensive know-how.
