To mark the Singapore Grand Exhibition, which is now into its second day, Patek Philippe has unveiled a special-edition World Time Chronograph ref. 5930G-011 for the Southeast Asian market.
Limited to 300 pieces, the watch has a white gold case paired with a smoked, red guilloche dial that darkens towards the edges. It features a dark grey city disc, on which “Singapore” replaces “Beijing” for the time zone of GMT+8.
The rest of the watch is identical to that of the standard version that was first unveiled in 2016 with a white gold case paired with a blue dial. It measures 39.5mm wide and 12.8mm in height, which is rather impressive considering it houses a full-rotor movement, with a vertical-clutch, column-wheel flyback chronograph as well as a world time module.
A corrector pusher at 10 o’clock advances the cities disc, hour hand and 24-hour scale in one-hour increments. All that needs to be done is to set the city corresponding to the local time zone to the 12 o’clock position. The local time will be indicated by the hands while the time in all other time zones can be read off the 24-hour scale.
The 30-minute counter for the chronograph is located at six o’clock, while the seconds scale for the chronograph is located between the cities and 24-hour discs.
Visible through the sapphire case back, the CH 28-520 HU movement is based on the CH 28-520 chronograph caliber, controlled by a vertical clutch, with the addition of a world time module based on the concept devised by Genevan watchmaker Louis Cottier in the 1930s.
The calibre CH 28-520 HU operates at a frequency of 4Hz and offers a 55-hour power reserve. It is equipped with a Gyromax balance wheel and Spiromax hairspring made of Silinvar, a patented silicon-based material. As with all special-edition watches with transparent case backs, it has a printed inscription that reads “Patek Philippe Singapore 2019”.
