Glo-Dial Clock Company

horizontal rule

The GloDial company made several of the classic styles of clocks. Based in L.A., they also produced clocks in New York City and Danville, Ill.

 The main styles they produced were clocks with a back-painted glass cover, a black face, with white numbers. They typically had green neon. However, this style did vary significantly. They also produced table top clocks, clocks with external neon tubes (rings or words), and produced more basic clocks within larger neon signs.

Note that several companies purchased clock bodies from Glo-Dial and customized them and labeled them as a different company. For example, the Barnett Film company customized Glo Dial clocks for movie and drive-in theaters. Also, the Neon Action company also sold Glo Dial clocks (and also related to Barnett), and even have the same New York address (580 Fifth Avenue).

Here's the standard style.  There's a lot of variety here, neon colors, face styles, advertising styles, and even optical illusion spinners.

This is a very similar style to the previous category, except there are multiple neon rings behind the glass. They even had external switches so different rings of neon could be lit. The overall clock body is larger, to accommodate more rings of neon.

Glo-Dial also produced table top clocks. There's at least two different models where the the base of the clock differs, and at least two different finishes.

Other styles - This is an example of the external neon lettering on a Glo-Dial. There's also a style thatis part of a larger sign. 

There's a lot of different photos of Glo-Dial clocks in my photo album. I've attempted to display only one of each style on the pages that are linked above.  Here's a gallery of the other Glo-Dial photos I have. 
Some of the  Glo-Dial clocks carry patent number 1994950 (click on the image or number to see the patent document). This patent was applied for by C.W. Hoffritz on March 24, 1934, and the patent was granted March 19, 1935. It is interesting that the patent describes not only the use of hidden neon to light the face, but also the design of the hands to reflect the light as well.
