Abstract
The invention relates to a chronograph mechanism comprising at least one minutes counter and one hours counter which are designed to be located both on the same side of the plate, first and second resetting members, each having a bearing surface and being able to pivot between a low position, in which each bearing surface cooperates with the periphery of a resetting cam of one of the counters, and a high position, in which each bearing surface is located at a distance from the corresponding cam. The mechanism comprises retaining means for keeping each of the resetting members in its high position, comprising a first retaining member acting directly on a first resetting member and able to be released in response to an action by a user, and a second retaining member acting directly on the second resetting member and able to be released in response to a pivoting of the first resetting member in the direction of its low position.
