An indication device is provided which has an electrically conductive fluid driven by an MHD pump. The fluid has an indicator surface driven adjacent indices of an indicator so as to indicate a quantity. A position of the indicator surface is sensed and controlled to ensure accurate indication of the quantity. Optionally, the quantity indicated is time.

Disclosed herein is a clock. The clock includes: a first belt; an hour axis unit comprising first and second rotation axis spaced apart from each other by a predetermined distance and being rotable; and an hour hand configured to point a position of the hour axis unit, wherein the first belt makes revolutions by being engaged with the first and second rotation axis.

A watch including: a first drive mechanism including a hand having a rotational axis along a first direction, a wheel train, and a drive power source; and a second drive mechanism including a hand having a rotational axis along a second direction different from the first direction, a wheel train, and a drive power source, wherein the first drive mechanism and the second drive mechanism are mounted separately. Each of the first direction and the second direction is defined along a normal direction to dial at a position of a rotational axis of the hand.

A watch including a watch case, the watch case containing a watch movement and two dials. The watch further includes a casing ring arranged inside the watch case, the watch movement being mounted in the casing ring so as to be suspended in a cantilever arrangement inside the watch case, the casing ring supporting the two dials.

A decorative element for watches, comprising: a framework comprising arms (12) delimiting a plurality of decorative areas (Zi) and forming support elements, and a plurality of decorative components (20) fixed to the arms of the skeleton, each decorative component occupying a decorative area.

A method for fabricating metal decorations on a domed dial made of insulating material, wherein the method includes the steps of forming a photosensitive resin mould by a UV LIGA type process, and electrodepositing a layer of at least one metal starting from the conductive layer to form a block, which substantially reaches the upper surface of the photosensitive resin.

A case including a device case, and an exterior member which is attached covering an outer circumferential surface of an upper part of the device case, in which the device case has a catching portion formed in an outer circumferential portion thereof, the exterior member has an engaging portion which is formed on an inner side portion thereof, engages with the catching portion when the exterior member is attached to the device case, and prevents the exterior member from being detached from the device case, and a support area which supports the engaging portion of the exterior member is formed of a material whose hardness is lower than hardness of a material of an area adjacent to the support area.

A wrist-worn device includes a main body having one of a retention recess and a retention projection and a bezel configured to cover at least a portion of the main body. The bezel has one other of the retention recess and the retention projection. The at least one retention projection engages with the at least one retention recess to removably attach the bezel to the main body.

In embodiments, a timepiece includes a case, a dial in the case, and a reflector underneath the dial. The dial has a plurality of holes through its thickness, wherein the dial is shaped to allow ambient light to enter a region behind the dial. The reflector is configured to direct the ambient light from the region behind the dial to exit through the plurality of holes.

A musical timepiece includes a gong fastened to a structure or a resonator of a watch case, the resonator rigidly assembled to the structure around a chamber, by lugs allowing vibration of the resonator within a determined frequency range, the chamber enclosing a sealing element forming with the lugs the only mechanical connection between the structure and the resonator. The structure or the resonator includes a groove receiving a gasket in contact with the structure and the resonator The structure structure or the resonator or the sealing element includes a rigid protruding relief portion compressing a gasket in its groove, with a hardness less than 20 Shore A, for minimum damping of the vibration of the resonator.
