Vintage Fiat 4  Day Automobile Clock.  I would assume this is from the 1920s. This clock measures 9cm in diameter at the bezel and measures  4cm from to back. The clock case measures 8cm diameter. The flaky cream dial read "Fiat,  Metron,  4 Giorni,   SA Officine Piedmontesi,  Via Parma 29 Torino". The original glass look to be in good condition. It could do with a clean as could the clock generally. The bezel screws are missing. The movement reads "51". The clock winds, sets and works properly and keeps reasonable time, but the spring will slip when attempting to fully wind, so it needs a service.
