A sub-assembly of external parts including, coaxially with a first component and a second component compressing together a sealing and friction joint, and interposed therebetween, a bolt securing them together by axially blocking the first component, and a lower surface of which lies, in the assembled position, in the vicinity of an upper surface of the second component, which bolt includes a lower relief protruding axially from this lower surface towards the second component, arranged to either complementarily cooperate with an oblong groove which is partially of revolution that the upper surface includes, and interrupted by a stopper limiting the angular travel between the second component and the bolt within a turn, or else to constitute an angular stopper to an upper relief protruding from the upper surface of the second component and extending axially towards the bolt.

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.

A watch case (6) including a rotating bezel (1), a middle (3) and a connecting spring (2) between the rotating bezel (1) and the middle (3), the connecting spring (2) being accommodated within a first groove (7) formed in an external wall (3a) of the middle (3) and within a second groove (8) formed in an internal wall (1 a) of the rotating bezel (1), the first and second grooves (7,8) being preferably arranged opposite one another. The connecting spring (2) is made of an alloy with memory of shape.

A movement for a timepiece comprises a plate (1) and an annular module (2) circumferentially surrounding the plate (1). The module (2) comprises a mobile ring (2″) mounted so as to be made to rotate about its axis by a rolling means, the mobile ring (2″) carrying a rotary indicator (3). The rotary indicator (3) is an attachment, of which a first part (3A) fixed to a crown (5) arranged on the mobile ring (2″) is flat and parallel to a plane defined by the crown (5) and a second part (3B) is a protruding curved part. The second part (3B), in the shape of a tip, is oriented towards the centre of the crown (5), the crown (5) comprising a housing for receiving one end of the first part (3A) of the rotary indicator (3). The movement further comprises a drive train (4) for driving the mobile ring (2″) in rotation at a speed of rotation imparted by the timepiece movement, such that, when it is driven around the periphery of the plate (1), the rotary indicator (3) displays time information indicating hours, minutes or seconds.

An annular rotating bezel system intended to be rotatably mounted on a middle part of a watch case inside which is housed a timepiece movement which extends in a plane, including a rotating bezel, an annular holding ring, a toothed ring, and at least one elastic arm of which a free end is elastically and radially meshed with the toothed ring, said toothed ring and said at least one elastic arm being held in an axial direction perpendicular to the plane of the movement in the bezel by the annular holding ring, either the toothed ring or the elastic arm being arranged to be angularly joined to the rotating bezel, and other being arranged to be angularly joined to the case middle; wherein the elastic arm is formed of a flat strip-spring mounted in a cantilever arrangement in the system.

A wearable device is described herein. The wearable device includes a display. The display can be a digital display with analog components. The wearable device also includes an input device. The input device is to control the digital display and the analog components correspond to the digital display. In some cases, the input device is a bezel.
