Patek Philippe Aquanaut Travel Time ‘Advanced Research’ 5650G
The Ref. 5650G Aquanaut is the recipient of two important innovations in the field of horology. At the beating heart of this watch is an optimized Spiromax balance spring made of Silinvar; with patented terminal curve and inner boss, an innovation that ensures greater precision within mechanical watches.
The second innovation is a compliant (flexible) mechanism crafted from conventional horological steel used to set the second time zone in time-zone watches. To showcase these innovations, the manufacture is launching the sporty and elegant limited edition Aquanaut Travel Time Ref. 5650 Patek Philippe Advanced Research, the first timepiece to be endowed with both of these avant-garde developments.
The Ref. 5650 Aquanaut Travel Time also contains the ingenious Patek Philippe time-zone function that apart from local time also displays the local date, a second time zone (usually home time) and a day/night indicator for both time zones. Its blue dial with the bright-dark gradation features the well-known embossed Aquanaut pattern and at 9 o'clock has an ample aperture through which the silvery steel flexible mechanism with the four crossed leaf springs, the meticulously finished surfaces, and the chamfered edges are clearly visible.
