ABSTRACT:
An extensible watch strap is made up from tubular links which extend transverse to the length of the strap. The links are arranged in two rows with the links in one row offset from the links in the other row. Each link is connected to the two adjacent links in the other row by U-shaped connectors which have limbs projecting into respective links. The limbs are received between pairs of leaf springs which act in the longitudinal direction of the strap and tend to push both of the limbs which are received in each link against each other.
