Abstract: A plastic case for an electronic device such as a wrist or pocket watch, has a bottom (1), a cover glass (2) and a support body (3), as well as a dial (6). The support body (3) serves as a base for the dial (6). The bottom (1) and cover glass (2) are fixed to the support body (3) by means of irreversible connections (7, 8). The irreversible connections have first self-locating structures (7) for irreversibly attaching the bottom (1) to a lower portion of the support body (3), and second self-locating structures (8) for irreversibly attaching the cover glass (2) to an upper portion of the support body (3) so that the support body (3) lies between the cover glass (2) and the bottom (1). The support body (3) can have attachments (12) for fitting holders such as a bracelet or chain or holders can be formed on the support body (3).

Abstract: The wrist watch according to the invention has a strap or bracelet (8) and a case, formed from three case parts (upper part or cover glass 5, middle part or dial, lower part or bottom 3) and in which is placed a clockwork with time indicating means, particularly hands, and has standardized connecting areas (9) in which the bracelet (8) and at least two of the case parts are interconnected or interconnectable. The connecting areas (9) are e.g. constructed as hinges and during assembly serve as orientation aids for the orientation of the individual parts with one another and as application and orientation points for the orientation and assembly tools, as well as as definitive or temporary connections between the case parts and the bracelet. Shape-differing watch models having the same, standardized connecting areas, can be assembled using a substantially identical assembly procedure and tools, which leads to a faster model change procedure.
