The Lake Geneva note is reinforced here, quite logically, by the name of Geneva replacing that of Paris on the cities disc, equipped with cartridges ensuring excellent readability. The 24-hour disc in white gold is divided into day/night zones. The openworked white gold hour hand is distinguished by its original shape inspired by the constellation of the “Southern Cross”.
The caseband and the minute repeater lock are adorned with a hand-guilloché “Clous de Paris” motif, emblematic of Patek Philippe, which can be found in a good number of its creations, in particular one of its very latest Calatrava. The openwork ties reveal this continuous guillochage.
First minute repeater always striking the local time, i.e. that of the time zone selected at 12 o’clock and displayed by the central hands, this model houses the R 27 HU caliber (3Hz) equipped with a unique and patented construction ( power reserve of approximately 45 hours).
As such, the two gongs of the minute repeater are not attached to the movement plate, but directly to the caseband in order to optimize the sound. For added sophistication, the watch has an automatic winding system with a 22 ct gold mini-rotor integrated into the movement – which allows this timepiece to maintain, despite its complexity, a particularly slim profile.
The new reference 5531G-001 is fitted with a shiny blue-green alligator strap with a white gold folding clasp. It replaces reference 5531R-012 in pink gold.
