It depends entirely on the condition of the movement. If the movement was in good shape, it should be able to do better, but it depends on who did the service and how decisions were made about replacing parts.
Then again, if it is losing the exact same amount each day, it could already be well serviced and adjusted, and just need regulating - the information provided does not allow me to make any sort of definitive judgment about your watch and situation.
