At the 2012 Geneva Haute Horlogerie Show, Parmigiani will launch a new Tonda calendar watch, using the brand’s newly developed 17th homemade movement PF 339. This movement is based on the PF 331 automatic movement, and has added annual calendar function modules.
Parmigiani’s newly developed 17th self-made movement, PF 339, has an annual calendar function. Its rarity lies in its daily practicality. It has the advantages of automatically taking into account the change in the length of the month, whether it is running for 30 or 31 days Without error. You only need to perform manual adjustment once a year in February of a normal year. The leap year will display the date February 29, and automatically switch to March 1 the next day.
On the automatic Tonda calendar, the date is indicated by a retrograde hand from 1 to 31 on the dial outer ring. The week indication is set at 9:00 and the month indication is set at 3:00, which is displayed in the digits from 1 to 12. The precise moon phase indicator developed in the brand watchmaking workshop is the finishing touch of this calendar. It only needs to be adjusted once every 120 years to reduce the deviation between the traditional monthly transport cycle (29 days and 12 hours) and the actual monthly transport cycle (29 days, 12 hours, 44 minutes, 2.8 seconds). This model offers two moon phase indicators, one for the northern hemisphere and one for the southern hemisphere. The moon phases are made of rose gold. The dial of the Tonda Almanac is made in the dial production factory of Fleurier. It is available in silver and dark gray, with a fine grain or barley grain decoration in the center and a black or silver plated matt ring. . The case is made of rose gold or white gold, which is also homemade by the brand, with a Hermes crocodile leather strap.
