Electromechanical flip dial Calendar clock, made by Solari Udine (Italy). Housing designed by Gino Valle.
Year of manuf. mid to late 1960's
Needs minute countwheel adjustment, sometimes the hour change over happens at 59 minutes, other times at 00 minutes. Gears from this clock are like Meccano gear wheels and can be adjusted on the drive shaft. I will add an other video of the inner workings on YouTube.
