Radio-controlled timepiece movement and method of assembly

摘要

A radio controlled timepiece movement includes a carrier structure and a wheel train mounted thereon. The wheel train includes a plurality of rotatable wheels each having a wheel aperture formed therein. The apertures are alignable with one another. A printed circuit board is mounted on the carrier structure and has a board aperture formed therethrough. An end of the board aperture disposed farthest from the wheels is covered by a portion of a conductor of the circuit board. A light beam transmitter is mounted on that conductor and disposed in the board aperture. A wire extends from the element to the second conductor. The transmitter and wire are embedded within a radiation-permeable material which fills the board aperture.
