You need to disassemble the auto-wind module, thoroughly clean the components, oil & reassemble. Common problem to which that is the solution.
And, for the umpteenth time (there are pinned articles about this in the watchmaking forums that should be read ) - the movements in most rep watches are used/unserviced. If this is a watch you plan to keep & rely on, you would do well to have it properly overhauled (fully disassembled, ultrasonically cleaned, oiled, reassembled & timed) by a professional watchmaker. That way, like all mechanicals, it should keep good time & run reliably for the next 5-7 years (the recommended time span between overhauls).
