The Patek Philippe Advanced Research Aquanaut Travel Time Ref. 5650G
Patek Philippe Advanced Research opens up a further chapter with the launch of two important innovations in the field of horological design. One of them is the 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.
The second one is a compliant (flexible) mechanism crafted from conventional horological steel that is used to set the second time zone in time-zone watches. To welcome these innovations, the manufacture is launching the sporty and elegant Aquanaut Travel Time Ref. 5650 Patek Philippe Advanced Research in a limited edition of 500 watches, the first ones to be endowed with both of the avant-garde developments.
