Forrest Maddix displayed three Warren Telechron clocks during show & tell. He remembered having a refrigerator clock like the one displayed when growing up. Don Dawes explained Telechron comes from "time synchronized at a distance".

Don Dawes presented "Henry Warren's Battery Clocks" made in the early 1900s. Their performance was comparable with contemporary mechanical shelf clocks at the time except they ran about a year and a half with one winding (battery change).
