PF702 is similar to the PF701, though the rotor is no longer platinum but rather tungsten. It was first used in the stainless steel Tonda 1950.
At just 2.6 mm thick, the PF701 movement owes its slim profile to an off-centred micro-rotor directly integrated into the main plate. This component winds the movement, which has an autonomy of 42 hours. This calibre was developed to allow for the addition of multiple functions — such as a calendar or moon phase indication — without altering the slender proportions of the Tonda 1950 family. This serves as proof of the excellent design of the PF701 movement and its successive variations.
