Abstract
Abstract Electronic watch module comprises spacer block which has openings therein for batteries, crystal can, etc. and has locating pins thereon. The watch electronic substrate is located on the pins and carries most of the watch electronics including chips, printed circuitry and LED displays on the front. A cover is located on the pins, extends over many of the electronic components and resiliently engages in the watch case. The spacer block, substrate with its electronics and cover comprise the watch module which is resiliently mounted in the watch case by the resilient engagement.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
An electronic watch module for use in a watch case having a downwardly facing stop surface comprising: a spacer block having an opening therein for the containment of a battery; a substrate having a front and back and having its back positioned toward said spacer block for contact with a battery in the battery opening and having electronic components on the front of said substrate; a cover positioned over at least part of said substrate for protection of at least part of the electronic components on the front of said substrate, a resilient web on said cover having a finger on said web for engagement with the stop surface in the watch case for positioning of said module within the watch case, said web being resilient so that said module is resiliently mounted in the watch case in a direction causing web deflection.
Claim 2
Dependent Claim
143 words
An electronic watch module for use in a watch case having a downwardly facing stop surface comprising: a spacer block having an opening therein for the containment of a battery; a substrate having a front and back and having its back positioned toward said spacer block for contact with a battery in the battery opening and having electronic components on the front of said substrate; a cover positioned over at least part of said substrate for protection of at least part of the electronic components on the front of said substrate, a resilient web on said cover having a finger on said web for engagement with the stop surface in the watch case for positioning of said module within the watch case, said web being resilient so that said module is resiliently mounted in the watch case in a direction causing web deflection.
Claim 3
Dependent Claim
18 words
The electronic watch module of claim 1 wherein said cover is formed of resilient synthetic polymer composition material.
Claim 4
Dependent Claim
41 words
The electronic watch module of claim 2 wherein at least one of said electronic components on the front of said substrate is an optical display and said cover is transparent over said optical display for permitting viewing of said optical display.
Claim 5
Dependent Claim
66 words
The electronic watch module of claim 3 wherein at least two locating pins are positioned on said spacer block and extend upward from the top surface of said spacer block, said substrate engaging said locating pins to locate said substrate with respect to said spacer block and said cover engaging said locating pins to locate said cover with respect to said substrate and said spacer block.
Claim 6
Dependent Claim
15 words
The combination wherein said watch module of claim 1 is positioned within a watch case.
Claim 7
Dependent Claim
63 words
The combination of claim 5 wherein said watch case has a battery contact spring positioned adjacent said battery opening in said spacer block so that when a battery is placed in said battery opening the battery is resiliently urged toward said substrate and into contact with said substrate to resiliently urge said finger into engagement with the stop surface in said watch case.
