Touch probe comprising a fixed member; a feeler held by one or several elastic elements in a resting position relative to said fixed member, said feeler being capable of moving from said resting position in response to a deflection force; a detection system comprising a light source driven by the displacements of the feeler relative to said fixed member; an optical image sensor receiving the light emitted by said light source; an optical mask interposed on the light path between said light source and said optical image sensor.

A watch case includes a middle (), one opening of which is closed by a bezel () and/or a crystal (), or by a back (). An element for closing the opening is connected to the middle by a resilient metal member () having a recessed cross-section defined by the profile of a non-rectilinear wall having a constant thickness, whose ends () are connected to the periphery of the closing element (), respectively. The profile of the non-rectilinear wall defines at least one annular fold having an orientation parallel to the plane of the opening, the fold being formed by a curvature whose arc defines an angle of between &#x3e;90&#xb0; and 180&#xb0;, so as to impart to the closing member () a freedom of movement relative to the plane of the opening.
