Abstract

The invention relates to a fly-back hand chronograph equipped with a device for controlling stopping and starting of a fly-back hand. <??>The aim of the invention is to produce a control device which does not require precise and frequent adjustments and which prevents premature wear of the pieces of the fly-back hand runner. <??>This control device comprises a fly-back hand clamp (101), a fly-back hand runner (103) arranged between the free ends (133) of the two branches (109, 111) of the said clamp (101), two fixed reaction members (115, 117) against which bears the linking portion (113) between the two branches (109, 111) of the clamp and deformation means (135) creating a force acting against the said reaction members (115, 117) on the said linking portion (113) in order to deform the latter. <IMAGE>
