ABSTRACT:
An expansion bracelet, particularly for wrist-watches, has a row of connected links. Each of these links has a plate member, a pair of solid outer members connected to said plate member at opposite lateral sides thereof, as seen with respect to the elongation of the row, and a solid inner member which is located between the outer members and partly projects beyond them in longitudinal direction of the row. The inner member has an underside which faces towards the plate member and is provided with a pair of transversely extending channels. A pair of substantially C-shaped brackets are provided, each having a bight portion pivotably received in one of the channels, and a pair of leg portions. The leg portions of one of the brackets are pivotably connected to the plate member so that this one bracket can be tilted longitudinally of the row out from between the outer members of the link. A pair of biassing springs are provided, each surrounding one of the bight portions. The biassing spring associated with the one bracket permanently opposes the tilting of the latter. The other bracket is connected in the same manner with a plate member of adjacent link, and its associated biassing spring also opposes its tilting.
