The Toric Rétrograde Hémisphère combines an iconic collection – the first created by Michel Parmigiani – with the world of travel. Its mechanical movement with automatic winding allows for the time in two different places to be read down to the minute, thanks to its two independent time indications.
The bezel with alternating gadroons and knurling is a distinctive feature of this Toric timepiece. To create this seminal element of the strength of the design inherent in this model, Michel Parmigiani was inspired by the structure of Doric columns. Knurling is a technique involving the manual fluting of material with a wheel that imprints notches into the metal. Each watch is therefore unique. It is made by a craftsman from the Horloger Division who has created the knurling of all Toric pieces since 1996.
Despite the complexity of its indications, the dial of the Toric Rétrograde Hémisphère is remarkably simple, elegant and readable. Its design remains perfectly balanced thanks to the symmetry between the day-night indication at 6 o'clock and that of the second hour at noon. Each dial’s texture is unique. It is obtained using a graining technique, which is an artisanal skill consisting of brushing the dial by hand with a mixture of silver powder.
The Toric Rétrograde Hémisphère has two independent time indications, each with down-to-the-minute accuracy, even for locations that have half-hour or quarter-hour offsets with the one-hour Greenwich meridian, which is the reference point. The crown at two o’clock enables the independent adjustment of the module regulating the second time indication. Once the adjustments are made and the crown pressed, the module reconnects to the movement resulting in the synchronised progression of the two times. Two day-night counters allow for the phase of the day to read for each time zone.
The Calibre PF317 with automatic winding allows for two time indications to be read, which can be independently adjusted down to the minute. Each time zone is associated with a day-night display. It is also fitted with an instant retrograde date indicated by the third central hand. Its two series-coupled barrels ensure 50 hours of autonomous and exceptionally regular operation. Its pendulum beats at a frequency of 28,800 vibrations per hour. Comprised of 316 components, this sophisticated calibre is decorated according to the highest Haute Horlogerie standards, with superbly angled, beaded and Côtes-de-Genève-decorated bridges and plate. Its oscillating weight is of 22 carat gold that is delicately engraved and stamped with the initials PF.
