Going Barrel (Fuseeless Mainspring Drive)
Needs researchThe shift from fusee to going barrel was a major enabler of thin, mass-producible watches, and the going barrel remains the standard mainspring architecture in mechanical watches today.
A going barrel drives the watch train directly from a mainspring barrel with a slipping bridle (or, in some designs, a stop-work-limited direct drive) rather than via a fusee's equalising chain and cone, trading some theoretical evenness of torque delivery for a much simpler, thinner and cheaper mechanism.
The going barrel's slipping mainspring attachment (rather than a fixed inner end) allows the spring to slip once fully wound, protecting against overwinding damage without the fusee's bulk, and became standard as lever-escapement watches proved tolerant of a going barrel's less uniform torque curve.
How to verify this yourself
As a trade-wide gradual transition rather than a single patented invention, there is no founding patent to search; verify claims about the timing and geography of the fusee-to-going-barrel transition against movement-survey literature and museum collection catalogues.
