The Tonda GT Chronograph returns to the forefront with functions and colors that lend it a sporty tone while remaining in the realm of complications. It appears in two versions: 18ct 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, provide a discreet yet very distinctive presence on the expansive dial while at the same time offering exemplary balance in the overall dial display.
