A watchcase has a turning ring provided on one case surface and enclosing one case section. The turning ring is secured by at least one holding element engaging a peripheral groove of the case section and securing the turning ring to t case section.

Watch case, in particular for a wristwatch, with a turning ring provided turnably on one case surface and for this purpose enclosing one case section, the turning ring being secured by at least one holding element engaging in one peripheral groove of the case section and securing the turning ring on the case section.

A device comprising an annular seal having an annular projection engaged into a groove in the edge of the watch glass is disclosed. The lower part of the seal, said lower part having a bulge, engages onto a surface of the housing and is compressed radially by the bezel. The inner lateral surface of the bezel, said surface being fitted around this seal, comprises two concentric cylindrical surfaces of different cross sections, the surface of larger cross section being that which is adjacent to th...

The timepiece includes a case formed of a back cover and a middle part closed by a glass arranged above a dial with an analogue or digital display, delimiting the housing of a watch movement, said glass being surrounded by two external rotating top and bottom bezels, superposed on a shoulder of the middle part. It is characterized in that the two bezels and the shoulder have identical or similar non-circular or non-symmetrical contours in relation to the center of the dial in the superposed posi...

The invention relates to a wrist device, particularly to a fastening mechanism of a cover part and a plastic body part of the wrist device. The fastening mechanism comprises a fastening structure, which in turn comprises a projecting grip structure extending at least partly into the body part, setting against a positioning surface of the body part, and blocked in relation to the mounting direction of the cover part to prevent the fastening structure from moving in a direction opposite to the mou...

A portable timepiece has a bezel rotatably disposed on a case body, and an elastically deformable gasket interposed between the case body and the bezel in an elastically deformed state to exert a frictional force on the case body and the bezel sufficient to maintain the bezel in a stationary rotational position though permitting the bezel to be manually rotated to any desired position by overcoming the frictional force. One or more lock members are movably disposed on the bezel and contact a sli...

The invention relates to a watch case comprising a case middle (16), a bezel (18) mounted so that it can turn on the middle and defining between them an annular chamber (36) and a gap (40) open towards the outside of the case, a glass (22) mounted in sealed fashion on the bezel, a seal (42) inserted between the bezel and the middle and arranged in said chamber (36). According to the invention said seal comprises a ring (44) of annular shape made of a material of the highly elastically deformable...

A timepiece has an annular case band having a front side end part that protrudes radially inwardly toward the inside of a case band and defines a front opening of the case band. A case back is detachably attached to a back side end part of the case band. An annular edge member seats on a front surface of the front side end part and has a tubular part removably inserted into the front opening of the case and, the tubular part having an annular attaching groove that opens to an outer periphery of ...

A timepiece has a case band having a front side end part that projects inwardly toward the hollow interior of the case band and terminates in a front opening. A case back is detachably attached to a back side end part of the case band. A glass is fixed to an annular edge member that seats on a front face of the front side end part. The edge member has a tubular part slidably inserted into the front opening and threadedly engaged with an annular attaching member in the interior of the case whereb...

A rotating-type bezel apparatus has a case body and a bezel rotatably mounted on the case body and having alternately spaced recesses and projections. A first member is mounted on the case body and has an end portion elastically engageable with surface portions of the recesses and projections of the bezel to impart a click feel to the bezel during rotational movement thereof. A second member is movably mounted on the case body for movement between a first position and a second position. In the f...
