A display device (10) for a watch movement, including: a display (11) intended to be mounted movable relative to a structure (12) of the watch movement and provided with a member (110) for indexing relative to said structure (12), and with a driven wheel (111) whose rotation causes movement of the display (11); a drive mechanism (20) including a driving wheel (21) intended to drive the driven wheel (111) in rotation; and a coupling mechanism (30) including a transmission wheel (31) meshing with the driving wheel (21) and the driven wheel (111), the coupling mechanism (30) being configured so that the centre of rotation of the transmission wheel (31) has a degree of mobility relative to the driving (21) and driven (111) wheels.

An electromechanical horological movement (2) including an electromechanical motor (54), a display wheel set (30) arranged to be rotated by the electromechanical motor and including an arbor (36) intended to carry a display hand (48), and a braking device associated with the display wheel set and including a braking spring (10) and a washer (8) arranged between the braking spring and the arbor of the display wheel set, the braking spring being arranged so as to be able to generate, via the washer against which this braking spring presses, a braking torque on the display wheel set, as soon as this display wheel set is subjected to a rotary drive torque. The washer and the braking spring are arranged so that the washer remains stationary and non-rotating in normal operation.

A modular watch (1) including at least a middle (10), a back (11), a display module (12) having a dial, time display, a crystal and a first magnetic gear, a horological module (13) including a horological movement with a second magnetic gear arranged to cooperate with the magnetic gear of the display module (12), and first and second bracelet strands integral with the middle (10) at a pair of horns (20, 30). The display module (12) and the horological module (13) are mounted one on top of the other, the display module (12) being mounted such that it is fixed against the middle (10), and the horological module (13) being mounted such that it can rotate between the back (11) and the display module (12) in order to set the time.

A sympathique watch (10) including a horological movement including a going train (20), a display train (30) connected to at least one display of a time value, a sympathique hand-setting mechanism and a crown (13) operated hand-setting mechanism. The sympathique hand-setting mechanism includes a coupling device (40) interposed between the going (20) and display (30) trains, the coupling device (40) being configured to adopt an uncoupled state in which it disengages the going train (20) from the display train (30) so as to allow the hands to be set on the display by means of the sympathique hand-setting mechanism, and a coupled state in which it establishes a kinematic link between the gear trains, the link allowing for sliding enabling the hands to be set on the display by means of the crown (13) operated hand-setting mechanism.

A mechanical watch or measurement instrument including metallic parts, wherein each part of the mechanical watch mechanism has a relative magnetic permeability of less than 1.01.
