The old version has two holes and the new version has one elongated hole.The elongated hole was a later improvement to the chrono mechanism so that the jumper could be adjusted. The old and new versions can be used interchangeably, but most times it boils down to preference, if you want to keep your movement “period looking”. Depending on when your movement was made it may have one or the other style used and most purists want to keep the same style of part so as to retain the collectible value(originality) of the movement. Ask questions before you buy. I will answer and help if possible.Thank you for looking
