Abstract
In an electronic watch containing an electric battery assembly of large size, particularly a battery assembly including several batteries or accumulators (), the diameter of a removable cover () closing a large bottom opening of the back cover () of the watchcase is limited by the fact that the cover is provided with a bayonet fitting device having locking members () radially directed towards the interior. These locking members catch on a fixed support () having one or more housings for the battery assembly. They are arranged at the top of a substantially cylindrical annular portion () of the cover. A sealing gasket () is placed around this annular portion and compressed radially against a cylindrical surface () of the periphery of the opening in the back cover, which ensures water-resistance even if the bayonet fitting is not screwed all the way in. According to a variant, the cover can form the entire back cover of the case.
