In the early 2000s, Patek Philippe introduced their Advanced Research series, launching exclusive wristwatches featuring cutting-edge technologies. This present watch introduced in 2017 covers two pieces of advancement designs which are made to enhance the long-term functional integrity of the piece.
The first innovation is the use of an optimized Spiromax® balance spring made of Silinvar®, featuring a patented terminal curve that improves the accuracy of mechanical watches. The second innovation is the incorporation of a compliant mechanism made of traditional horological steel, which is utilized to set the second time zone in watches that display multiple time zones. Moreover, the distinguishing characteristics of this model include a noticeable aperture at the 9 o'clock position. This reveals the flexible mechanism with four crossed leaf springs. The 5650 also displays local time and date, a second time zone, and a day and night indicator for both time zones. This is truly one of Patek Philippe’s finest innovative pieces where advanced technology is emphasized in a modern wristwatch.
