Abstract: A wristwatch is described, including a middle having a side wall, defining a median plane and further having attachment members for securing respective first and second ends of a strap to the middle, and a cover capable of pivoting, relative to the middle, between a first closed position in which the ends of the strap are locked onto the middle, and a second open position in which the ends of the strap are free to be separated from the middle. The cover is arranged so as pivot about a rotational axis parallel to the median plane, each attachment member including a hole provided in the side wall and intended for receiving the corresponding end of the strap by insertion in a direction substantially parallel to the median plane.

Abstract: A case for a timepiece, of the wristwatch type, comprises a middle, a back and attachment members for attachment to a bracelet. The back is attached to the middle to pivot between open and closed positions, to use the timepiece as a table clock when it is in the open position. A first attachment member allows the attachment of a chain to use the timepiece as a pocket watch, and a second attachment member comprises at least one recess arranged so that one bracelet end can be inserted therein, in the open position of the back, and locked by the back when it is closed. The invention also relates to the corresponding timepiece and to an assembly comprising such a timepiece associated with adapted bracelet and chain. Advantageously, the transition from any configuration of the timepiece to another configuration can be carried out without using a tool.
