Reply To: Pinion replacement

[Bob Tascione]

Hi Dave,
It would be possible but you would need to make sure the pinion is actually pressed onto the arbor. Most are either cut as part of the arbor or are safety pinions which are threaded onto a threaded seat on the arbor. This allows the pinion to unscrew itself from the arbor preventing pinion and or gear train damage in the event of a sudden reverse of power as a result of mainspring breakage etc.
What make of watch is it?
