PURPOSE: A rolling method of polished round rods for a push button of a watch is provided to reduce part and labor costs by removing the need of polishing the push button separately. CONSTITUTION: A rolling method of polished round rods for a push button of a watch comprises the steps of: passing a pulled round rod through a first ring and inserting it between a pair of rolling dies(S10), polishing the round rod surface with the rolling dies with central axes deviated at a certain angle(S20), and passing the round rod through a second ring(S30). The round rod is inserted and discharged in a straight position.
