Abstract
A fly-back chronograph provided with a stop-start control for the fly-back hand is provided. The control does not require careful and frequent adjustment and avoids premature wear of the fly-back wheel parts. The control device has fly-back pincer, a fly-back wheel disposed between the free extremities of the two branches of the said pincer, two fixed reaction members against which a connecting member between the two branches of the pincer bear and deformation means creating a force acting against the said reaction members on the said portion of the connecting member in order to deform it.
