Telechron probably made the clock itself but I wouldn't swear to it
without a closer inspection. Nutone sold many, different integrated
doorbell clocks and this was one of them. Is it me or does that minute
hand look like it got too much vitamin B-1 as a child?
This children's clock was made by Irmi but carried a Telechron movement.
Guild Crest clock
Guild Crest sold a bunch of these. All seem to be gold and in the Art Nouveau style. I don't care for these even a little.
