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 slip-preventing part provided on the case body. A manually rotatable holding ring engages with the lock members and is rotatable in one direction to increase the contact pressure between the lock members and the slip-preventing part to thereby prevent unintended rotation of the bezel, and is rotatable in the other direction to decrease the contact pressure to thereby permit manual rotation of the bezel by overcoming the frictional force exerted by the elastically deformed gasket. In this manner, inadvertent rotation of the bezel is prevented by structure other than the gasket thereby preventing undue wear of the gasket.
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 position, and in that the bezels can occupy a first rest position in which concealed parts of the shoulder and/or concealed parts of the bottom bezel are made visible after rotation of at least one bezel.
The watchcase includes a middle part (3) closed by a back cover (5) delimiting a housing (7) provided for receiving a watch movement (9) including at least one off-centre display (10, 12). The external surface is entirely covered by a cover-bezel (1) rotatably mounted in the plane of the case on an axis (15) located at the centre of the case and it includes at least one aperture (20) having the same contour as the display (10, 12) and able to occupy a first position in which said display (10, 12) is visible, and another position in which said display (10, 12) is concealed.
The present invention relates to an analog wristwatch including a watch body and at least two bezels. The watch body further includes a face, along with an hour hand and a minute hand for telling time. The at least two bezels surround the circumference of the face and are rotatably mounted to the watch body. The bezels are used to measure elapsed time.
To provide a timepiece having a bezel which is easy to set in position, and which is not inadvertently rotatable after it has been set in position. A bezel is rotatably mounted on the bezel mounting portion of a case band. A click member is held vertically movably in the stepped hole of the case band and is urged toward the engaging portion of the bezel composed of a plurality of serrations. An operating member which has a depression having an oblique push-up surface and a closing surface contiguous to its push-up surface is held movably in a accommodating portion formed in the case band and crossing the lower end of the stepped hole at right angles thereto. The operating member is urged to its position in which its closing surface closes the lower end of the stepped hole. A stopper member capable of entering and leaving the depression along its push-up surface is positioned between the click member and the operating member. The member is movable to restrict the movement of the click member by the stopper member supported on its closing surface, while releasing the click member from such restriction and permitting its vertical movement by allowing the member to drop into the depression.
