Abstract: Embodiments are directed to a smartwatch including a housing that at least partially defines an internal volume, and a touch-sensitive display positioned at least partially within the internal volume. A front cover can be positioned over the touch-sensitive display and can define a front exterior surface. A seal can be positioned between the housing and the front cover and configured to transition between an uncompressed state and a compressed state in response to an increase from a first external pressure on the front cover to a second external pressure. In the uncompressed state, the seal has a first density and is air-permeable allowing an internal pressure of the internal volume to equalize with external air at the first pressure.

Abstract: A timepiece movement includes a magnetic escapement formed of a magnetic escape wheel with an annular magnetized structure and a pallet fork whose shaft is formed by a ferromagnetic material. The pallet shaft exerts on the escape wheel a magnetic disturbance torque due to the fact that the annular magnetized structure exhibits an angular variation of at least one defining physical parameter thereof, such that the magnetic attraction varies as a function of the angular position of the escape wheel and has a tangential component. A magnetic compensation pin is incorporated in the timepiece movement, this magnetic compensation pin being arranged such that the second magnetic disturbance torque that it exerts on the escape wheel exhibits an angular phase shift relative to the first magnetic disturbance torque generated by the pallet shaft, so as to compensate largely for this first magnetic disturbance torque.
