Works out at about 5mA. Measure the resistance of the motor, and that should tell you what voltage to offer it. There wont be a lot of power there.
Does it appear to have brushes and a commutator as well as the field winding? If so, it will have been intended to run in one direction only (sensible for a timer). If the rotating bit is a magnet, then its an AC only motor, and will need some electronicery to drive it. This is very logical for a timer - such a motor will be locked to mains frequency and be relatively unaffected by voltage making timing accurate.
