One aspect of the invention relates to a device (100) for maintaining or limiting the shake, in at least one direction, of a timepiece component (30), said device comprising a stationary structure (20) arranged to abuttingly receive at least one surface of said component (30), and a rotary bolt (10), cooperating with said stationary structure (20), the rotary bolt (10) being rotatable about an axial direction (A) between a first angular position, referred to as the unlocking position, allowing said component (30) freedom of movement and a second angular position, referred to as the locking position, limiting the travel of said component (30) relative to the stationary structure (20) in said at least one direction, characterised in that said second angular position, referred to as the locking position, of the rotary bolt (10) is secured by resilient return means (3).

The invention relates to a marine chronometer comprising a clock mounted on a support, for example mounted so that it can be inclined with respect to the support by means of a gimbal mounting, the clock comprising, inside a case, a mechanical clock movement driven by a barrel, the clock also comprising a rewinding control member engaged with a rewinding geartrain for rewinding the barrel.

The chronometer according to the invention is wherein the rewinding control member comprises 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 said through-spindle being engaged with the barrel rewinding geartrain.

This invention relates to a locking gimbal (10). More specifically, the invention relates to a locking gimbal (10) for automatically locking a gimballed object against motion arising from an external force (F.sub.E) applied thereto; and automatically releasing the gimballed object on removal of the external force (F.sub.E). The locking gimbal (10) includes a first object (12) pivotable about a first pivot axis (P.sub.F), a second object (14) movable along an arc cantered substantially at a second axis, a locking member (16) and a locking formation (18). The first object (12) defines a first reference axis (A.sub.RF) passing through the first pivot axis (P.sub.F) and a center of gravity (CG.sub.F) of the first object (12), whereas the second object (14) defines a second reference axis (A.sub.RS) passing through the second axis and a center of gravity (CG.sub.S) of the second object (14). The first and second objects (12, 14) are movable relative to one other between a first aligned condition, wherein the first and second reference axes (A.sub.RF, A.sub.RS) are substantially aligned, and a second displaced condition, wherein the first and second reference axes (A.sub.RF, A.sub.RS) are angularly displaced relative to one other. The locking formation (18), actuated by displacement between the first and second objects (12,14) is radially movable relative to the first pivot axis (P.sub.F) between engaged and disengaged position, wherein: (i) in the first aligned condition, the locking formation (18) is in a disengaged position and spaced from the locking member (16), permitting rotation of the first object (12) about the first pivot axis (P.sub.F); and (ii) in the second displaced condition, the locking formation (18) is in an engaged position and in contact with the locking member (16) thereby preventing rotation of the first object (12) about the first pivot axis (P.sub.F).
