Abstract
Abstract Digital display is retained in upper spacer of watch module by means of screws and a spring having resiliently deflected fingers engaging the upper spacer. Resilient deflection at both the screw attached end and the spring finger end resiliently restrains the display and ensures contact of the display with an elastomeric type connector.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
A digital watch module comprising: a top spacer having a pocket therein for receipt of a digital display device and electrical contacts in said pocket for making contact with a display device in said pocket, said pocket having a bottom to serve as a limiting position of a display device in said pocket; a digital display device sized to fit within said pocket and being positioned within said pocket and resting on said bottom; a spring frame engaging over said display device and engaging in said top spacer for resiliently restraining said display device and retaining it in said pocket, said spring frame having first and second spring fingers thereon respectively engaging in first and second spring-finger recesses in said top spacer, said spring fingers being resiliently deflected to urge said spring frame downwardly on the said display device, said spring frame further having first and second tangs thereon and a screw through each of said tangs and into said top spacer for retaining said spring frame with a respect to said top spacer.
Claim 2
Dependent Claim
174 words
A digital watch module comprising: a top spacer having a pocket therein for receipt of a digital display device and electrical contacts in said pocket for making contact with a display device in said pocket, said pocket having a bottom to serve as a limiting position of a display device in said pocket; a digital display device sized to fit within said pocket and being positioned within said pocket and resting on said bottom; a spring frame engaging over said display device and engaging in said top spacer for resiliently restraining said display device and retaining it in said pocket, said spring frame having first and second spring fingers thereon respectively engaging in first and second spring-finger recesses in said top spacer, said spring fingers being resiliently deflected to urge said spring frame downwardly on the said display device, said spring frame further having first and second tangs thereon and a screw through each of said tangs and into said top spacer for retaining said spring frame with a respect to said top spacer.
Claim 3
Dependent Claim
51 words
The digital watch module of claim 1 wherein said tangs on said spring frame have tang ends thereon, said top spacer having shoulders positioned under said tang ends, said tang being unsupported under said screws through said tangs so that said screws urge said spring frame down against said display device.
Claim 4
Dependent Claim
58 words
The digital watch module of claim 2 wherein said display device is a liquid crystal display device and a resilient connector is positioned underneath one edge of said display device for a connection between said display device and connections to the watch electronics, said tangs being positioned along the edges said resilient spring frame over said resilient connector.
Claim 5
Dependent Claim
23 words
The digital watch module of claim 3 wherein said spring fingers are positioned on said spring frame adjacent corners away from said tangs.
