A smart watch and a method of replacing components of the same are disclosed. In one aspect, the smart watch includes a display panel including a body portion having a polygonal shaped planar structure and a corner portion extending from one side of the body portion and being bent away from the surface of, and at the side of, the body portion. The smart watch also includes a housing disposed under the display panel and having an area that is smaller than the combined area of the body portion and the corner portion. The corner portion is defined by the one side of the body portion and two adjacent sides.

A platform for displaying several mutually different horometric items of information, includes as many crowns as the horometric items of information to be displayed on the platform. Each of the crowns is arranged to receive an associated information support and is movable in rotation at a speed selected according to a horometric item of information displayed on the associated information support.

A centralized control unit for controlling an arm moving in a clockwise direction and in a counter-clockwise direction includes an arbor about which the centralized control unit pivots. The arm is integrally mounted on a toothed actuating wheel as an assembly, and the assembly is mounted to freely rotate about the arbor. The centralized control unit also includes a wheel to control the arm in the clockwise direction, a wheel to control the arm in the counter-clockwise direction, and a power wheel kinematically connected to an independent barrel to drive the arm.

A timepiece sub-assembly includes, irreversibly fixed to a main plate and each irreversibly pre-adjusted by the irreversible securing of adjustment and/or assembly components, after the particular timepiece function thereof has been adjusted and function checked on the test bench, functional modules including a gear train module, a display module, and a time-setting module. Other mechanical sub-assemblies, each irreversibly fixed to the preceding lower order mechanical sub-assembly, include various modules including motor module, frame-mounted self-winding device module, escapement holder regulating module, motion work train, date module, and self-winding module. A mechanical movement including at least one mechanical sub-assembly of this type and a watch including a mechanical movement of this type are also disclosed. A method of assembling mechanical sub-assemblies of this type by the irreversible securing of mechanical sub-assemblies and irreversibly pre-adjusted modules is also disclosed.
