The Benrus Dial O Rama is an excellent example of 1950’s styling and is available in several different designs. The one you see bellow used calibre: FG25 based on FHF calibre 73.
Although the Dial-O-Rama features three rotating disks and a dial with windows, its basic construction is that of a conventional watch. Actually its minute disk and seconds star differ from an ordinary watch in shape only. In some variations regular hands are used. The biggest change from a standards model is the hour disk, jumps. This mechanism is closer related to a date mechanism that will activate every hour.
