Visconti issued the Pontevecchio limited edition  in 1995 to celebrate the 650th anniversary of the Pontevecchio bridge in Florence, one of the most famous bridges of the world.

The colors chosen for the three pens  symbolize the different stones which were used to build the bridge: Adriatic stone ( light gray/azurite with black streaks), Granite (a mixture of burgundy and gray tones), Pompei (deep cobalt blue and orange).

The three pens are are converter fillers and are fitted with a 18 ct gold nib.

The outline of the Pontevecchio bridge is engraved on the cap band while the serial number is placed on the large band on top of the cap.

The Triset comes with a guarantee but no outer box.
