From the 1920s onwards, Cartier encouraged watchmakers to develop very small movements for its precious watches. This enables the watch case to blend into the jewellery design and sometimes even be concealed altogether. The smallest mechanical movements ever produced were soon used by Cartier in its "baguette watches". They were highly admired as decisively contemporary ornaments in the period between the wars.
