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.
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.
