Possibly a winding indicator on chronometers and some high class RR watches this indicated how much (mileage) was on the movement in hours since it was last wound and was used by the operator to keep tabs on the state of the wind, a small dial usually at twelve O clock high! 40 Hours was the usual type by Elgin, some other ones had a 32 Hour indicator.
