A method for acquiring data on a sympathetic clock () for setting the time of a sympathetic watch () at request. The sympathetic watch forms with the clock () a sympathetic assembly (). The watch includes an hour display () and a minute display (), a reference position of which will be defined at a reference time, and the clock () performs the time setting of the watch (), either when the watch () is placed on the clock (), or alternatively at a predetermined time on the clock (), or at request by action of a user on a control means () included in the clock () or the watch (), or upon control of a horological movement () included in the clock ().

Sympathetic timepiece assembly

A timepiece mechanism for returning the seconds hand to zero, which includes a seconds arbor; a seconds hand; a cam forming a snail cam path which extends in a spiral around the seconds arbor from an inner end to an outer end connected to each other by a radial stop surface; a hammer carrying a cam follower, rotatably mounted about a hammer axis between a disengaged position wherein the cam follower is removed from the cam path and an engaged position wherein the cam follower presses on the cam path; a retaining ratchet system including a toothed wheel and a click which engages with the toothed wheel.

A marine chronometer includes a clock mounted on a support, for example mounted so that it can be inclined with respect to the support using a gimbal mounting, the clock including, inside a case, a mechanical clock movement driven by a barrel, and the clock also including a rewinding control member engaged with a rewinding geartrain for rewinding the barrel. The rewinding control member includes a rewinding control geartrain positioned on the outside of the clock, secured to a spindle passing through a wall of the case via a bearing, the through-spindle being engaged with the rewinding geartrain.

Device for rewinding and/or immobilizing a marine chronometer

A marine chronometer including a watch tiltably mounted on a support with a gimbal suspension, the chronometer support also includes a cradle movable in translation between a rest position wherein the watch is free to move on the gimbal suspension, and a holding position wherein the watch is resting on the cradle.

An attachment device is provided for two elements of a watch band to allow the two elements to be hooked into place or unhooked. The first element includes at least one bar on one of its ends. The second element includes two grooves, each including a longitudinal opening respectively opposite one another, and one of the two elements can move from an unhooked position. One of the elements is oriented in a predetermined angular position in relation to the other element, to a hooked position, in which the two elements are coplanar after a rotation of a predetermined angle of one of the two elements in relation to the other so that each groove is articulated on the bar to hold the two elements hooked to one another.
