The second watch on the list, the 5930 World Time Chronograph, has a hand-guilloched dial in a smoked red color with white and red markings for the minutes/seconds scale.

Reference 5930, a Baselworld 2016 novelty, combined Patek's expertise in flyback chronographs with their superior understanding of world time mechanisms.

Patek reproduced this timepiece for the 2019 Watch Art Grand Exhibition with Singapore (Rolex Daytona Replica) as GMT +8 in the city ring of the world time mechanism. The timepiece is otherwise unchanged, with the CH 28-520 HU caliber powering the mega-complications.

The timepiece is a 39.5mm white gold piece with a sapphire back with the inscription PATEK “PHILIPPE Singapore 2019”. It will be produced in a limited edition of 300 watches.

Calatrava Pilot Travel Time was launched in Baselworld 2015 as the white gold 42 mm reference 5524. Patek then released a smaller version of the watch, the 7234 in rose-gold, just ahead of Baselworld 2018.

Calatrava Pilot Travel Time, as its name implies,Oris Replica Watches has a dual-time zone mechanism that indicates local and hometime. The day/night indicator in the apertures helps to indicate local and home time. The subdial at 6 o’clock indicates the local date.

Patek created this variation of the model 7234 in stainless steel with a gray-blue dial for the 2019 Watch Art Grand Exhibition.

The watch has an embossed blue leather strap, and a sapphire back with the words "PATEK SINGAPORE 2019." This piece has a limit of 400.

Ref. 5167 - Aquanaut

It's pretty straight forward. The robust 40.8 mm Aquanaut in stainless steel with red minute marks and the central second hand. The composite strap for this special watch also uses red.

The watch is powered with a caliber 324 S C visible through the sapphire caseback inscribed "PATEK SINGAPORE 2019.
