Haute Horlogerie brand de Grisogono introduces a new aesthetic to its flagship Instrumento collection, Instrumento N° Uno Annual Calendar. The dial of this annual calendar adopts a subtle asymmetry to display the calendar indications, with a large date at 12 o’clock and the month at 8 o’clock. Small seconds are shown at 5 o’clock. Instrumento N° Uno Annual Calendar delivers a practical function with infinite sophistication: the date should be corrected just once a year, at the end of February. This beautifully balanced timepiece features a new strap design which integrates seamlessly with the case, ensuring an even more commanding presence on the wrist.
