The present application discloses an electronic wristwatch with an easily adjustable rotating crown, comprising a watch case, and one side of the watch case is provided with a bezel, the other side is provided with a bottom cover, and the watch case is provided with a movement, the external side of the watch case is provided with a circular operation hole, and an adjusting gear is provided in the circular operation hole, the adjusting gear comprises a circular disk, and the side edge of the circular disk, which is close to the movement, is provided with a tapered row of teeth 1 along the circumferential direction, the side of the circular disk, which is away from the movement, is provided with a connecting post, and the free end of the connecting post is provided with a threaded post, the connecting post is externally sleeved with a crown tube.

A control device (1) for a timepiece has: - a body (4) intended to be mounted to be able to rotate about an axis of rotation (X) in a case middle (2) of a timepiece in order to drive a mechanism of the timepiece, and: - a crown head (5) movable in translation with respect to the body, parallel to the axis of rotation, between a first position and a second position. The body has a first coupling means (46) and the crown head has a second coupling means (53), arranged so that when the crown head is in its first position, the body and the crown head are uncoupled, and when the crown head is in its second position, the body and the crown head are coupled, the control device further comprising a locking element (6), a first formation (47A) and a second formation (47B), the locking element being able to cooperate with the first formation to stabilize the crown head in its first position, and with the second formation to stabilize the crown head in its second position, the locking element being integral with or fixed to the crown head and the first and second formations being integral with or fixed to the body, or the locking element being integral with or fixed to the body and the first and second formations being integral with or fixed to the crown head.

A case for a timepiece having a middle, a rotating bezel, and a device for blocking the rotating bezel, the device including an end-link, mounted mobile relative to the middle between a first position capable of preventing the rotation of the rotating bezel and a second position capable of allowing the rotation of the rotating bezel, the end-link including an action and/or gripping portion arranged so as to allow the wearer of the timepiece to move the end-link relative to the middle, while wearing the timepiece.

A sub-assembly of external parts including, a bolt interposed between a first component and a second component compressing together a joint, securing them together by axially blocking the first component, and which cooperates with the second component to enclose a ball occupying a well of depth greater than its diameter, that an orientation housing in the second component or the bolt includes, framed by channels of depth less than its diameter, limited by stops, which ball can occupy, when subjected to the gravity field and/or a magnetic field, both an orientation housing and a complementary housing of depth less than its diameter, that the bolt or respectively the second component includes, for their relative drive by the ball when it is simultaneously braced on a channel and a complementary housing.

A bezel assembly for a watch wherein a plurality of resilient devices, such as springs or balls, are positioned within a plurality of ramps within the case. A plurality of rod end screws are also inserted through a plurality of corresponding apertures of the bezel and into the case in order to prevent the bezel from rising up from the case when the balls are pushed up the ramps by the resilient devices. As the bezel is turned in a clockwise direction, the resilient devices exert pressure upon the balls in an upward direction toward and against the bezel so that the bezel is prevented from moving in the clockwise direction.

A method for assembling at least a first element and a second element to form, once assembled, an external component for a portable device, including the steps of: a) making the first element; b) making the second element; c) arranging at least a first groove in the first element and at least a second groove in the second element; d) placing and holding the first and second element end-to-end with at least a third connecting element which is inserted and locked in the first and second grooves.

Frame comprising a case body (3) and a glass (13) rotatably mounted on said case body, in which at least one interior annular channel (26) is arranged between the glass and the case body and comprising at least one holding means (32) of the glass on the case body and, between the glass an d the case body, a non-return means (35, 38) said means being arranged at least partially in said interior annular channel (26), in which frame the g lass h as at least one through passage (39), left free, for access to said interior annular channel (26), providing permanent communication of said channel with the exterior.
