Device for fixing a battery in a watch

摘要

The battery strap member comprises a ring (2) which is applied to the battery (4) and two fixing lugs (6). Each lug comprises notches (8, 10, 12) which co-operate with a slot 24 in the insulating substrate (20a). The notches form three bayonet-type closure systems which define three battery heights. The device thus makes it possible to use a single strap member for a watch which accepts batteries of three different thicknesses, while all being of the same diameter.
