Inspired by the golden ratio of architecture, Parmigiani Fleurier reintroduces the Tonda GT Chronograph in 2022 with two sporty new versions: An 18K rose gold chronograph with big date functions (as shown) and a cool steel chronograph with annual calendar functions (available here). For a pop of contrasting personality and color, both versions come with a choice of Quantum grey or Granata red counters and complementing athletic vulcanized rubber straps. 

Ref. PFC903-2020002-400181

The extremely accomplished Tonda GT chronograph with its sizeable 42mm diameter case features an integrated self-winding chronograph calibre that provides a 65 hour power reserve. Three counters are presented in Quantum grey or Granata, artfully displayed by 3, 6, and 9 o'clock axises, with the double date window set at 12 o'clock. Thanks to its high-frequency (36,000 vibrations per hour) this incredible timepiece and allows for short-time measurements up to 12 hours with 1/10th of a second precision. The exceptional mechanical movement is visible through the exhibition style case-back, protected with sapphire crystal.
