Wall or mantel clock, with digital flip display and calendar function with white Arabic numerals. Day of the week, day of the month, month, hour and minutes. Quartz electronic movement.

These examples are the Spanish version of a functional-looking clock manufactured by Solari in the early 1960s. They were wall clocks designed by brothers Nani and Gino Valle, who won a design award for this simple, clock with its straight lines, devoid of decoration but effective in keeping time, especially in workplaces and public spaces.

This clock is the forerunner of the rotating letter and number displays still used in stations and airports around the world.

There was also a mantel or desk version, which was rectangular.

Many of these clocks were manufactured and marketed by Unión Relojera Suiza.

La Unión Relojera Suiza S. A. was founded in Spain in 1923 as a representative to the best Swiss watch manufacturers. In 1932 the company was expanded and a timekeeping division was created to study, develop and maintain synchronised time systems. Most of its products were originally intended for industrial use. Its clocks were renowned for their precision and functionality and sold around the world.
