In 1780 a clock with four dials was installed, and in 1959 the tower was demolished and then rebuilt according to the design of engineer Alfonso Augello. The square-shaped shaft, crowned with Guelph battlements, rests on a broad base composed of four panels, the last of which houses the current clock, supplied by the Frassoni company of Rovato (BS).
At specific times of the day, the three bells play the whistle of the people of San Cataldo: “vacabunna va a travaglia” (“lazybones, go to work”), an invitation to idlers to get busy and live up to the reputation of the locals, known for being hardworking people. The idea is attributed to Maestro Gesualdo Valdino Lo Bianco (+1980), who proposed to create a dialogue between the civic tower clock and the one in the tower of the Church of the Rosary, in a sort of musical duet.
