JUMP! (JUMP!) You might as well jump! The jump hour has a long history, beginning in mid-nineteenth century France and stretching all the way to today with numerous brands putting their own spin on the “complication.”
Now, first things first, it can’t technically be called a complication since the accepted definition of complication is a mechanism that provides information other than the time. Therefore, retrograde hands, jump hours, constant force mechanisms, and the all-mighty tourbillon are all (technically) excluded.
That being said, anyone who gives a hoot will say in the same breath that there are many complications that don’t fit that definition, because to many a complication is something that goes above and beyond showing the time simply by the traditional, never-ceasing hands.
And I couldn’t agree more.
