The invention relates to a tool for actuating a push-button corrector equipping a portable object of small dimensions, said actuating tool comprising a body that extends between a rear end defining an area for grasping the actuating tool and a front end defining an area for actuating the actuating tool, the actuating tool further comprising an actuating rod arranged such that it slides in a coaxial manner inside the body, the actuating rod being capable of moving from back to front and from front to back between a retracted rest position wherein it is retracted in a stable manner inside the body of the actuating tool, and a protruding working position wherein it protrudes outside of the cap, the actuating rod remaining in the protruding working position thereof as long as an axial pushing force is exerted thereon, and returns to the retracted rest position thereof as soon as the axial pushing force is released.

A watch corrector (100) including at least one case (110) and at least one mobile element (120). In order to avoid a movement according to a degree of freedom, the at least one mobile element (120) is inserted by force, preferably, the at least one mobile element (120) includes at least one second immobilisation member (125) configured to immobilise the at least one mobile element (120) in the at least one case (110), and the at least one case (110) is inserted by force, preferably, the at least one case (110) includes at least one first immobilisation member (115) being configured to immobilise the at least one case (110) in the watch middle (200).

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.

The invention provides a timing apparatus that can generate timing information regarding a plurality of regions without performing a complex calculation that uses software and without causing a significant increase in electric current consumption. The timing apparatus includes: a lower counter that generates a count value that indicates a time in seconds; a first group of upper counters that generates a first group of count values that indicate a time in minutes, hours, days, months and years by performing a count operation in synchronization with the count operation performed by the lower counter; and a second group of upper counters that generates a second group of count values that indicate a time in minutes, hours, days, months and years by performing a count operation in synchronization with the count operation performed by the lower counter.

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.
