The Ref 5930, introduced in 2016, incorporated the famous world time complication along with a sophisticated flyback chronograph, marking a historic first for Patek Philippe's watchmaking. This timepiece not only boasts an attractive design, but it also fulfills all the requirements for an elegant dress watch suitable for frequent travelers.

During its debut at Baselworld 2016, the reference featured a striking blue dial and held the distinction of being the thinnest world time chronograph movement ever produced by Patek Philippe. The redesign of the world time dial included the addition of a fifth-of-a-second division scale between the city and 24-hour rings. Additionally, the 30-minute counter was placed at 6 o'clock, enhancing both the legibility and overall balance of the dial.

With the growing popularity of the Ref 5930, Patek Philippe decided to release another eye-catching variant at the Singapore Grand Exhibition in 2019. Produced in a limited edition of 300 pieces, the current watch features a vibrant red dial reminiscent of Singapore's national flag while the smoky red guilloché added an extra layer of depth to the dial's aesthetics. Furthermore, the city between Bangkok and Tokyo was changed to Singapore and the caseback was written “Patek Philippe Singapore 2019” to align with the exhibition's theme.

Combining rarity and exceptional aesthetics, the current reference is highly sought-after and rarely available in the market. It is now making its debut in the auction market and is considered one of the most collectible world time chronographs available, especially when accompanied by its full set of accessories.
