This is an interesting Lucite desk or table clock that measures 6-1/2” wide by 4-1/2” deep and is 5-1/2” in height. The assembly weighs 6 pounds. It consists of a large acrylic block with a slanted face, a clock mechanism that slips into the block, and a covering for the clock.

There isn’t a label on the clock but the simple black and white clock face says “MADE IN ITALY LIC. ATO 2 JEWELS”.
What initially caught my eye was the similarity of the face to the Cronotime clock by Pio Manzù for Ritz-Italora. The back of the clock confirms my suspicions and reads:
This is a Ritz-Italora model of the clock, but it is likely a later version as the back of this clock is in transparent plastic whereas the back of many of the early editions are metal.
