Parmigiani Fleurier Tonda GT Chronograph Rose Gold..Reference Number: PFC903-2020001-400181

The Tonda GT Chronograph returns to the forefront with functions and colours that lend it a sporty tone while remaining in the realm of complications. It appears in two versions: 18k rose gold with chronograph and big date functions; and steel with chronograph and annual calendar functions.

Just as in architecture, the golden ratio dictates the ideal proportions and requires watchmakers to constantly reinvent the volumes and positioning of the elements composing a timepiece. This is the condition that ensures that creations remain just as desirable over time as on the first day of their appearance. In both cases, the color choices for the chronograph counters in Quantum Grey or Granata lend them a discreet yet very distinctive presence on the generous dial offering exemplary balance in the display of the functions.

Structured Space

The Tonda GT Chronograph with its substantial 42 mm diameter case in 18ct rose gold houses an integrated self-winding chronograph calibre operating at a rate of 5 Hertz, i.e. 36,000 vibrations per hour, beneath the silver-toned guilloché dial with its "triangular hobnail" motif. Short-time measurements are read off on the "Quantum Grey" or "Granata" subdials, judiciously positioned to structure the space harmoniously arranged and nicely balanced by the big date display appearing in a twin aperture at 12 o'clock.

Visible through the transparent sapphire crystal caseback, this top-quality mechanical movement boasts a 65-hour power reserve, 331 components including a sandblasted 22ct gold oscillating weight and a column wheel. It is clearly finished to the highest standards of Haute Horlogerie. It also enables short-time measurements of up to 12 hours with 1/10th of a second precision thanks to the high frequency of its regulating organ.

This extremely accomplished chronograph, water-resistant to 100 metres and equipped with the distinctive finely knurled and polished bezel, is fitted with a deep red or grey rubber strap matching the colour of the subdials and secured by an 18ct rose gold folding clasp.

"Triangular Hobnail” Guilloché

The same "Quantum Grey" and "Granata" colour scheme between the counters and the rubber strap also applies to the Tonda GT Chronograph in stainless steel featuring an annual calendar, with a knurled bezel framing the silver-toned guilloché dial in a "triangular hobnail" pattern. This 42 mm diameter chronograph is water-resistant to 100 m and features modern lines with subdials in one or the other of the colours, classically arranged along the 3 o'clock to 9 o'clock axis and topped by the double date window at 12 o'clock. It is equipped with an in-house self-winding chronograph calibre operating at a frequency of 4 Hertz (28,800 vibrations per hour).

The movement is also endowed with an annual calendar, a useful additional complication that is easily adjustable. This sophisticated mechanism is comprised of 443 components, including a 22ct rose gold oscillating weight, and enables the wearer of the timepiece to no longer have to worry about the length of 30 or 31-day months. Once set, the integrated complication automatically handles monthly transitions until the 28th of February each year and on the first day of March, the calendar can be manually adjusted to change the date from February 29th to March 1st.
