With its 11-hour dial the Solothurn clock in an original design not only indicates "Solothurn time", but also plays the "Solothurn song" on 11 bells, usually at 11.00, 12.00, 17.00 and 18.00. A special characteristic of the clock is the harlequin which strikes the hours. This beautiful metal sculpture was designed by the artist Paul Gugelmann of Gretzenbach/SO. The project promoter is the family business Trigona AG, Lengnau. The "Solothurn clock" can be admired on the West wall of the UBS branch at Amthausplatz 1 (Schanzenstrasse side) in Solothurn.
