de Grisogono presents the new Instrumento N° Uno Tourbillon, a watch that reveals to the eye, through its pink gold dial with sapphire details, the TB-31-00 calibre that animates it. The porthole on the caseback is also made of sapphire. A further touch of elegance and preciousness is offered by the black diamond set in the crown (0.10 carat). The strap is made of brown alligator leather and is fastened with a rose gold buckle. The watch is also available in a platinum version. Price: on request.
