A timepiece display device comprises a timepiece body, a support plate, a timepiece driving module, a rotating optical disc, a magnetic element, a top plate, and a rotating shaft of the timepiece driving module passes through the support plate and connects to the center of the rotating optical disc to drive the rotating optical disc to rotate; a display comprises an annular base mounted in the upper chamber of the timepiece body, a dial mounted inside the annular base, an indicator element placed on the dial and corresponding to the time identifier on the dial, and a crystal covering the upper end of the annular base. The indicator element and the magnetic element are positioned by the magnetic attraction of the magnetic element, and the indicator element moves synchronously with the magnetic element to indicate the time.

A timepiece is equipped with a case that includes a case middle, a pusher, and a locking device for this pusher. The pusher is arranged movably in a translational manner in an actuation axis. The locking device contains a blocker that is movable in a translational manner along the actuation axis and with the ability to be displaced between a locking position and an unlocking position, in which positions the pusher is respectively to the locking and unlocking positions blocked and free in translation. The locking device contains in addition a control rotatably mounted in a general plane of the case between a first position and a second position corresponding respectively to the locking and unlocking positions for the blocker, this control containing structure for driving the blocker between its locking and unlocking positions.

A liquid powered device, including a housing assembly configured to be worn on the wrist of a user. The housing assembly includes a front portion and a back portion. A liquid tank assembly is secured within the housing assembly. The liquid tank assembly has a fluid inlet. A power assembly is secured within the liquid tank assembly. An electronic module assembly is secured within the liquid tank assembly. The power assembly is in fluid communication with the fluid inlet to provide filling of the power assembly. The power assembly and the electronic module assembly are each separately liquid sealed. A pressure relief assembly is positioned within the liquid tank assembly for relief of undesired pressure therein.
