Abstract (en)
[origin: US4815054A] In order to enable a watch movement to be mounted in a case having a back cover integral with its case band, the manual control device of this movement comprises a shaft having a terminal pair of resilient claws. Notches are disposed in the claws and grip a pin disposed diametrically in the central housing of the crown. The body of the crown is manufactured in one piece with a sleeve engaging in a bore of the case band. The movement is inserted with the shaft by presenting in slantwise, then the crown is put into place by forcing the pin between the claws to introduce it into the notches.
