Abstract

The present invention concerns a chronograph watch fitted with a going train including: a permanent seconds wheel set secured to a permanent seconds display member, a chronograph seconds wheel set cooperating with a coupling in order to be secured to a chronograph seconds display member, and a third wheel set including a first third wheel fixedly mounted in rotation, meshed either with the permanent seconds wheel set, or with the chronograph seconds wheel set. The going train further includes a second third wheel mounted to move freely, meshed on the one hand, with the permanent seconds wheel set, and on the other hand, with the chronograph seconds wheel set.

Description

technical field [0001] The invention relates to the field of horology. More particularly, the invention relates to a chronograph equipped with a permanent seconds counter and a precision seconds counter. Background technique [0002] A chronograph of this type generally comprises a running wheel train forming the energy transmission chain from the energy accumulator element, the barrel to the energy distributor element, the escapement. This running train usually consists of a center wheel set, a third wheel set and a precision seconds wheel set mounted in series between the barrel and the escapement. The running train further comprises a fixed seconds wheel mounted in parallel with this third wheel set, fastened to the fixed seconds display element. Mounted in this way, the fixed second wheel set is positioned at the end of the gear train consisting of the center wheel set, the third wheel set and the fixed second wheel set. [0003] Because the fixed seconds wheel set is...
