ABSTRACT:
A hatch cover is positioned in the hatch opening in the watch back over a battery receptacle in the watch module. The hatch cover is mechanically retained in the hatch opening by means of a snap-in friction fit. It has a rim on the watch back. A groove in the back adjacent the rim permits insertion of a tool to snap out the hatch cover. The watch back can remain on the case during battery change to hold the module in the case.
