In 2015, the Instrumento Uno has been optimized and enhanced by a number of aesthetical and technical improvements.

The strap - made of black or brown alligator leather and equipped with a triple blade folding clasp - is fully integrated with the case. The case middle now features a refined, minimalist design, as the fastening elements initially visible on the sides of the case middle have been concealed inside the case. The corrector has been redesigned and integrated within the dual-time module and enables correction via the crown stem, which is adorned with a black diamond. The dial is available in dial black or old silver.

The self-winding mechanical movement, calibre DF 11-89, powers the hours and minutes, the dual time,  and the date at 7 o ’clock. It has a 42-hour power reserve and beats at 28,800 vph. It features a new blackened oscillating weight, decorated with open-worked “volutes”.
